Original subtitles

They're saying it's left the station with some passengers still on board,

but without the driver.

We appear to have been hijacked.

Hack-jacked. There's phone jammers on board.

They have requested to scan the comms from above.

This is satellite. That phone is used to converse only with us.

So, who have you been speaking to?

The National Cyber Security Centre.

What are you doing?

I'm a journalist.

The CCTV footage...

Shows the guy who snatched the bag at Glasgow Central, meeting

the woman he snatched it from.

The woman with the pram goes into a hotel near the station.

See if they can get footage from inside.

But if not, get it yourself.

C'est un problem britann... TRANSLATION: This is a UK issue.

Not a French one.

Get into Voya Rapide Systems.

Do whatever you need to do.

I'll do my best for you if you'll do your best for me, OK?

Can't choose a criminal over a Member of Parliament.

I'm not a criminal.

If you don't take care of this, things may get very messy.

What's that, Pev?

It's a goods train.

You need to move everybody out of the front carriages

and prepare for impact.

There's a train on the line in front of you.

Get in!

Come on!

METAL SCRAPES

PASSENGERS SCREAM

JOE!

Joe?

ON HANDSET: Joe?

RTV showing train still moving.

RAGGED BREATHS

Then why aren't they responding?

We all heard the collision.

Abby?

The comms planes reported back.

I'm not sure the person who installed that device

is in the waiting room at Motherwell.

What?

BEEP

BLOWS ON HANDSET

Joe?

Yeah.

Yeah, I'm here.

SHE GASPS

Oh, my God.

Ha.

Ha.

You all right?

HE GROANS

BREATHES RAPIDLY

Am I OK?

The comms plane is showing that there are two phone jammers

down there blocking up the whole train, and the single board

computer's receiving external messages via the satellite system.

So, the driver is driving in real time?

There has to be a large element of pre-programming or AI,

but they're obviously directing it.

I don't understand. How does that suggest the person who installed

the SPC isn't at Motherwell?

It doesn't.

BEEP ON TABLET

This does.

That new signal represents an unaccounted-for satellite phone.

I mean, this suggests that someone involved is still on board.

You all right?

Let me find something for that.

Hey, sit down. Sit down here.

Sit down. Oh! I got it, I got it.

Thanks. I got it.

What just happened?

A goods train was blocking the line.

They moved it. Do you think they could move it earlier next time?

They know what they're doing.

And they do want me to help them.

Well, I'm not sure those two things go together.

I spoke to them. He's telling the truth, OK?

We're never getting off, are we?

I'm bloody getting off!

No, no, no, listen, listen.

Hey, we're all definitely getting off.

We just need to stick together, all right?

All right, does anyone still have any objection to me taking the lead?

Is everyone OK, Joe?

HE SIGHS

Everyone's alive.

A bit battered, but alive.

OK.

All right, listen, um, I, I think we have a problem.

We definitely have a problem.

We have a plane over five miles above you, scanning

the communications and signals on board

and giving us on-the-scene Intel.

It has picked up a second satellite phone on there

attempting to make a phone call in the last 15 minutes.

They were using an encrypted line, and the call didn't last long enough

for the team to break it. But if they try again, so will we.

What are they saying?

One of the passengers may be working with the hackers.

Hey, she's talking to you!

What are they saying?

They just said we need to stay calm.

Everything's going to be OK.

HE LAUGHS HYSTERICALLY

Abby, I found a firearm.

What?!

We were looking for the jammers.

Did you move it?

The important bit.

What are you going to do?

Watch.

Look...

..whoever's behind this has hacked into the station information boards,

requested a ransom and calling themselves the driver.

The US are pointing the finger at a group based out of Tehran.

So has someone on there been recruited by them or...

..is it someone else entirely?

Why would anyone stay on board?

I don't know any more than you, but I'm worried

we're about to find out.

Don't trust anyone.

I'll forward the names through to Uniform

as soon as they come through.

Yeah? Yeah. Should I try and get the thumbnail profiles

of the open source?

Chase the CCTV up from the hotel in Glasgow, too?

Hmm. Yeah. Listening. And what about digging into the Tehran group,

looking at connections? OK.

You're on mute, sir.

BBC News on the line.

They're asking if reports of a train derailment and explosion at Gretna

are connected to the cyberattack on the rail network.

France have declared war.

The cheeky bastards are briefing that

what they're referring to as "the long, underfunded British infrastructure"

has made a cyber attack on our railway network

a bloody inevitability.

They're pinning this on us before anyone pins it on them.

Do we want an NPAS helicopter?

There's one on standby in Newcastle.

Abby? Abby?

The police helicopter.

Abigail.

Ma'am. Press.

The answer is no!

Message from the Home Office - prove France wrong.

Show that there isn't any risk out there that our cybersecurity team

can't deal with.

Tell me that's true, Abby.

Because I have to give Cobra an update in 12 minutes.

And...

If you're filming with that phone, darling,

then it's going straight out of the window.

You threaten anybody else and you're going out the window.

You need to stop drinking.

Free bar, you said.

It's not working.

I wouldn't worry about it.

What's that?

Uh... I got this on my first day.

I was a guard back then, you know?

And then a few years later, they says, oh, these wrist watches,

you've got to gie them back, you know?

But I didn't.

Never dropped a second.

Never, ever had.

I'm Chrissy.

Yas.

Thank you.

Hey, you helped me, didn't you?

When everyone else ran.

I'm like you, yeah?

All this therapy...

..fresh start.

Qualifications.

Well, I didn't see you turn round to help me!

Please, sir. I'm only gonna say this once.

Oh, here we go.

Shut up! I can see it coming a mile off.

Shut up!

Here we go! SHUT UP!

So, Miss Draycott, have you handed in your resignation yet?

Like my dad.

So, why did you?

What?

Come back?

How could I no'?

SHE EXHALES SHARPLY

I've never seen so many before.

Have you?

What?

I don't think I have.

No.

You know, if you're standing on Phobos - do you know Phobos?

It's one of Mars's moons.

And if you were standing on it and you jumped,

jumped up in the air, you'd never come back down again.

You'd just keep on going up and up forever.

I like the sound of that.

I spent enough time going the other way.

Oh, God.

I need to make a call.

Now.

The Cyber Security Centre's got me on hold.

Told me to stay there.

Do you want the train to stop more?

Can I have that, as soon as it's free, please?

It's not a payphone.

I know - it's MY phone.

Should I keep searching for the phone jammers,

or is there anything else...?

My wife is in labour.

At the UCH, in London.

And the thing is, she has pre-eclampsia

and this liver thing, which means it's been really difficult.

She's at risk of bleeding, and the baby...

Oh, mate.

I'm not after a hug, pal.

I just don't want you to think I'm some teenager

struggling without TikTok for an hour.

I am going out of my fucking mind waiting on a message.

Yeah?

HANDSET BEEPS

There isn't one.

There isn't one.

How about I ask the centre?

I'm sure your wife's pretty busy at the moment.

If we call the hospital, we'll be waiting forever.

If I ask them, they will be able to find out what's going on.

And as soon as I know, I'll tell you.

Have you got any?

Kids?

One. A boy.

And were you there...

..when he was born?

He'll know you, you know.

Already.

He'll know your voice and they'll bloody love you.

Don't worry about that.

Starting the bonds...

is the easiest thing in the world.

It's keeping it going that's the hard bit.

Now, can you help with the jammers?

Good man.

Come on.

It's not weakness.

The way you feel.

You have to be psychotic not to feel it.

I'm fine.

You look like shite.

My feelings are a little chemically skewed right now, but I do remember

the feeling and it was never in response to anything

like this actually happening.

It was just the fear of it by people thinking,

as people always do, something never having happened

or just never happened to them means that it never will.

Oh, God, I could do without my body collapsing!

Just adrenaline.

It's fine.

Hey, I haven't ever forgotten what your dad said to me, you know?

When I came round that night, I was sitting in your kitchen

telling him what we would do for you, what we could do

if you could cope with it all.

"Don't doubt her," he said.

"Don't ever doubt that girl."

Ah!

OK.

I was sorry to hear about him.

I...

No.

HE CLEARS HIS THROAT

HE SIGHS

It doesn't matter who you are.

There's a before and after, isn't there?

When they're there and when they're not.

SIREN WAILS IN THE DISTANCE

Why would anyone with any amount of involvement

stay on that train, Pev?

From Glasgow, OK - but Motherwell?

Can't answer that one.

Let's just say there's...

It is this BBG - this Iranian hacking group.

I'd rather not. How do they think it ends?

The operating company hands them a million.

They hit the brakes and then that's it?

We don't look any closer at who was actually involved

on the ground?

I'm not sure we can get into their heads, but we can get

into their code and we WILL stop that train.

Hmm?

What if we don't?

Almost our entire focus has been on stopping the train.

Yeah.

What if we don't stop it at all?

FROM HANDSET: Abby?

Abby.

Yeah. The oil rigger has a situation with his wife.

Could someone there contact a hospital for me?

Yeah. Tobe.

Why are some of the lines dotted?

They're...they're freight only.

Yeah.

I need the direct line back

to the signalling control desk at Manchester.

And, ma'am, I'd appreciate it if you would speak

to the UK Rail's Gold command.

Why?

I want assurance from them and you,

that they'll do whatever I say.

Yeah, UCH.

Thanks.

WIND BLOWS AND TRAIN CLATTERS OVER TRACKS

SHE SIGHS

SHE EXHALES SLOWLY

WIND BLUSTERS

Got it. Yep.

UK Royal Gold command signalling control.

Hi. This is Abby Aysgarth again.

Yes. I need you to take the 9-Alpha 272 Heart of Britain

off the West Coast mainline at Carlisle, and put

it on the line to Settle.

That's not possible at Carlisle, I'm afraid.

Train's almost there.

Maybe 30 minutes?

Abby, what are you doing?

Carnforth before it can switch.

Do it now, please.

Just clear the WCM of traffic.

It has to be now.

It's going too fast.

Do it now. Look, even if I wanted to,

I don't have the authority. Ma'am?

What are you doing?

I can't breathe in here.

Here.

No.

What the fuck is going on?

Are you sure about this?

Yes. Do it now.

SCREAMING

BEEPING

What have you done?

BEEPING CONTINUES

Is everyone all right?

Did we hit something again?

Dear God!

I think the pantograph...

..just smashed into the top of the tunnel.

The what?

The thing that connects us to the overhead wires.

Is everyone all right?

Mouse?

My screen's cracked. Come here, mate.

Sit down.

I warned you about that bloody thing.

People need to know.

Come here.

This isn't the West Coast mainline.

What is it, then?

RAPID BEEPING

Yes. Yes. I'm here, I'm here.

Where are we?

You...

You're taking the tourist route?

Yeah, I'm not sure there's currently an appetite for sightseeing.

You are on the line to Settle.

And the train, what happened? - the lights, the noise.

Yeah, this one isn't electrified.

So how are we still moving?

The diesel backup's kicked in.

So if we take you on to the freight line further south, we'll be able

to put you on a loop.

Till the diesel runs out.

Yes, till the diesel runs out!

I didn't have enough time to stop the train, so I thought

I'd stop the clock.

You...

You're literally going nowhere now.

But what if the driver does something?

If they're still holding out for a ransom,

that, that's a bad idea.

And so what if someone else is controlling the train?

We've got the points, the signals, the network.

You...

Well, you're just going round and round and round now.

To wait until the diesel runs out to remove the acting.

Or are you going to do it now?

Get Gold command to remove all passengers and goods trains

on a new route. Yep.

Abby, I've had a glass of wine, half a champs and a serious

surge of hormones.

I think I love you!

ABBY LAUGHS

Yeah, one step at a time.

Tell everyone what's going on.

Abby?

The French homework you gave me.

We uncovered a chain between the Tick... TOC!

Train Operating Company.

..and FOC and ROSCOs - basic error on the firmware in the PLC.

They couldn't patch it with the software because the scheme

was physically burned onto a dedicated

crypto authentication chip.

Please, please, use the English bloody language.

Every company involved with the Heart of Britain's

operation knew it was vulnerable to a hack, but did nothing

because it was cheaper to live with the risk.

And that means if you could get your hands on this,

so could potentially anyone?

I'm sorry, but how did you get hold of that?

KNOCK ON DOOR

Passenger social media profiles are ready upstairs.

Leave the investigating to us.

Uniform are currently kicking doors down of everyone still on board.

But we only use the back doors and we don't kick in.

We log in.

Get North Yorks Police out to the line

and track the train as closely as possible,

and get Armed Forces to reassess an area landing

once it's crossed the viaduct and is on the loose.

What did I just say?

Nice one, Abby.

Thank you, Ma'am.

Um...

What's wrong?

The oil rigger.

How long is it going to take.

For the fuel to run out?

Well, I wouldn't put your coat on right away.

There's enough backup diesel to take us all the way to Paris.

What?! For God's sake!

Take my word for it. This is a really, really positive development.

Oh, please! Can I have that phone now?

This is a bloody nightmare.

Abby? Yeah.

There's a girl on board.

Early 20s.

Right? She threw her bag out the window just before Carlisle.

Why?

I was hoping you might be able to find it and tell me.

We can try.

Did she give a reason? No.

She's going to have to do in a minute.

ABBY: Oh, Saj, I need you to get on to Cumbria Police.

You OK?

Yeah, we're on it.

All right, Abby, I'll let you go.

Joe?

Yeah.

Skye Geoghan, the oil rigger's wife.

She's in emergency surgery.

The hospital say that the situation for mother and child is critical.

I'm sorry.

Said they're going to update us within the hour.

Should be clearer then.

What happened?

Yeah, thank you.

Uh, they brought us off the main line away from the electrics.

Put us onto a loop.

Uh.

Eventually the diesel will run out and we'll stop.

So we're just going to go round and round for hours!

Have you heard anything?

Have they...?

Have they managed to speak to the hospital?

Not yet, mate.

I'm sure they will, sir.

Have you seen that girl, yeah, the one with the headphones?

So, we have Daniel Geoghan. He's an oil rigger

at Finis Brae.

Twice fined for affray.

He's used to being suspended from a rope above the North Sea,

so doesn't scare easy.

Obviously, the minister we know, and I'm assuming

we can count her out.

Let's hope.

LAUGHS WRYLY

But then there's a staff - William 'Billy' McCloud -

he's worked on there for nine years.

No social media, no profile, no digital footprint at all.

And Yasmin Brown.

Got coming up two interesting things on her profile -

an emotional post a few weeks back, saying that their staff of three

was being cut to two and that they were having to reapply

for their jobs.

Oh, that'll be about right!

Possible financial motive? Yes.

Which may also be true of Sophie Warren.

Now, she's currently studying for a PG Cert in Counselling.

Seems she's been selling off everything she owns over the last

few months, travelling with her father-in-law,

who used to drive that very service.

His son was left at Motherwell, says he's suffering from heart failure.

Well, if he wasn't before...

And that leaves?

11-year-old boy, who we've discounted.

So, Rachel Li, Digital Lifestyle Trends reporter

Arran Moy, who's a senior accountant at McCann's firm

that's been accused of sanction busting in the Middle East.

Christina Doolan, she's a solicitor.

Human rights focused, sues the government about once a month.

And Erin Connolly, she's a student at South Central University

in London.

She'd been working at the Station Hotel back home in Glasgow

over the holidays.

The hotel where Erin Connolly works...

..it's not the same hotel that the woman with the baby

at Glasgow Central was last seen heading into, is it?

Hey, Tobi?

Yeah.

Trawl the hotel CCTV for Erin Connolly.

Can I have a word?

About?

It's about why exactly you threw your bag out of that window.

HE SIGHS

Hello.

Go on.

Ah, hello!

Ha!

Ha! Got her!

I...

I don't know what you're talking about, weirdo.

I just saw you.

Are you OK? No, no, I'm not.

The woman with the baby.

She's with the passenger. All right?

Now, watch...

You know, I don't think my confidence in the police could get

any lower, but he is...

I saw you.

HE GROANS

Hey, wait, wait!

Get off me! What are you doing?

This is it.

What's she doing?

Wait! Wait! There's someone else there.

Get the footage from that camera.

What are you doing? What's going on?

Joe? Let go!

Move!

Someone on board met with one of the people who deliberately

delayed the train beforehand.

It wasn't some chance encounter.

They were waiting her for about ten minutes

and they took something from them. Yeah. It's OK. I'm with her now.

No, no, Joe, it's not the student.

Joe?

Hey, hey, hey. You don't put your hands on anyone.

You don't understand.

Someone on here is part of this.

Joe?

Joe?

RAGGED BREATHING ON HANDSET

Joe?

Joe, do you...?

DISENGAGED TONE

HELICOPTER BLADES BEAT

RING TONE

It's engaged.

What are we doing relying on him?

I'm used to relying on unreliable people.

Abby, we're encountering some, uh, difficulties in our support

of UK Rail's Gold command.

Difficulties?

We're trying to unpick the virus in the antivirus, but we appear

to be under attack ourselves from an outside source.

Tehran? Attempting to geo locate.

Magpies.

Well, that's... That's how I knew this was going to happen, you know?

You want to sum up how broken the whole thing is,

you can do it in one word.

Magpies.

You see?

HE GROANS

Oh, it's terrible!

If a train hits a small bird and it's delayed,

and that's the operating company's fault.

Large bird.

That's UK Rail's fault.

Your fault, mine.

But how does a magpie fit into all that?

Is it small or large?

Well, I'll tell - you when you're waiting on the platform

and your train hasn't come, when you've been on the line

for hours and it still isn't moving, you need to know that somewhere out

there, there are hundreds of people, delay attributors,

and they're not talking about you.

They're not even talking about your train.

They're just arguing about magpies.

The Germans, the Italians, the Dutch and the Japanese are now suspending

all their rail services in this country until further notice,

citing conversations with our friends at Voya Rapide.

Our train is now at the centre of an international incident.

Hey! Open up!

Part of it. Part of it - how?

You thought I could have something to do with this?

Well, what did you throw out?

Just stuff I'd rather the police didn't see.

Not... What?

Ket, some benzos.

Fucking hell!

I'm just working my way through uni like everyone else.

JOE SIGHS

Open up!

Why hasn't anyone else arrived?

I said. Well, send taxis - get drivers to buzz till they answer

and drag them here!

I don't care if they're in their PJs, their nighties,

their birthday suits.

Incident room, now.

Tell Hud about the reporter and find me anything you can.

SHE SIGHS

We have optics.

Do we have contact with their control room?

Alpha-Lima-seven.

This is November-Charlie-one, over.

November-Charlie-one, this is Alpha-Lima-seven, over.

How close can your team get, over?

Can vary a lot. They need to stay clear of tunnels, bridges, trees.

And it's currently accelerating significantly, over.

It is?

Joe?

If everything's under control, why are we going so fast?

She's talking to you.

Hey!

The point and the signals are under control.

The engine isn't.

And these points aren't made for a locomotive going at this speed.

Pev, what's the train's maximum speed?

Well, it's not the train's maximum speed we need to worry about.

Well, what is it? It's the lines.

What is it for them?

It depends how curvy the track is.

Not much above 100.

They are cracking the rail at that speed.

And... How much is not much?

I thought it was safe now.

Difficult to be certain.

Well, you need to be certain.

You can only be certain if the train crosses it.

Hey, don't igno...

There's no way we should be relying on that man.

You know, I never thought I'd agree with anything that you said.

What are you talking about?

If it wasn't for him... What is that for?

Oh, my God. What?

Alpha-Lima-seven, this is Abby Aysgarth.

Is there any chance that your team can get alongside it, even briefly?

We've currently lost connection with our man onboard,

and we're growing increasingly concerned.

And it would really help if we could get eyes

into the carriages, over.

Alpha-Lima-seven?

They can try, over.

You need to tell us exactly what's going on.

It's not me you need to be worried about.

It's her. Move.

All right, listen up.

Is that an axe?

OK?

OK.

SCREAMING

What's happening?

Why have we stopped?

It's the north.

Delays are inevitable.

No.

No, this will be us.

This will be us.

It's over.

Shit!

It doesn't look over.

Excuse me.

Are you hurt, mate?

No, I'm all right. But the lady isnae.

Which lady? The lady in the wheelchair.

Come on, show me. She's bleeding.

BUTTONS BEEP

How do you open the door?

Have you seen where we are?

If you ever shout at me again?

Unless a driver releases it, it needs a key.

There, the staff will have one.

LOCK CLICKS

COMMS: November-Charlie-one, this is Alpha-Lima-seven.

You're going to lose visuals from the EC135 now, over.

Alpha-Lima-seven, this is November-Charlie-one.

Why, over?

North Yorks Police look like they're going to be late

to the party. We've been instructed to set down two of our team as close

to the viaduct as we can, over.

How long will it take them?

How close can you get, over?

Pretty close. I'd say we can have them on board

in seven to eigh minutes, over.

Thank you, Alpha-Lima-seven. Out.

I'm sorry I had to get this out there.

What? Have there been any messages for me?

Do you really trust the government to tell the truth about what's

happening here? We're doing everything we can.

From what I could see,

no-one even knows there's been a hack-jacking yet.

No! They're only talking about a cyber attack on the network.

Nothing else.

It's not the job of government to alarm people.

Insert joke here.

I've tweeted out as much info as I can.

Trust me, it's better for us if everyone knows.

All I want to know is why you met one of the people who delayed us

at Glasgow before they did?

I didn't.

Don't just stand there.

I need your help to get Chrissy off.

How can we possibly get anyone off?

Answer it.

Abby, can you please tell me what's going on?

Joe, Listen to me. The police are boarding in five, six minutes.

The police are here. They're going to be on the train in five minutes.

This is almost over.

Anything?

No.

I served you.

Are yous listening?

We need to get everyone off whilst we can.

Look, look!

You are going nowhere.

See, this is what she's like.

Do you or do you not know anything

about what has happened here tonight?

Come on! No-one moves...

..until the police come.

Well, do you?

ABBY: Joe?

Yes. I knew it.

I knew it!

Joe, are you there?

PASSENGERS TALK OVER EACH OTHER

It's difficult to talk right now.

Where are your people, Alfa-Lima-seven?

Are they on the viaduct?

Repeat - are they on the viaduct?

Abs?

Three minutes, Joe.

Three minutes.

Just three minutes.

All right, I did...

meet someone.

I'm not involved.

I swear I'm not.

But I guess she is, the woman whose bag was stolen.

Seemed to be.

Continue.

I was contacted anonymously a week ago.

She said there was going to be an incident.

Incident?

In the Heart of Britain, travelling from Glasgow

to London.

Tonight.

And they wanted me there to report it.

Why you?

I didn't know the answer to that myself until...

Until? It became apparent what that incident was,

that the train had actually been hacked.

Why?

I've been working on a piece for months

about the hacking community.

I don't just want to aggregate news, write shit puff pieces and copy

and paste promotions.

I want to write something that means something.

Something about where we are.

About the gods of today.

Gods?! Holding governments and companies to account

from their bedrooms.

Terrorising people from their bedrooms.

I went to Europe's largest hacking convention.

Interviewed as many people as I could.

I'm guessing that one of those behind this is amongst them.

You knew it was going to happen?

Not exactly.

You knew something was. Something.

You risked our lives for a career boost.

If I'd known anything like this was going to happen, I'd have hardly got

on board myself, would I?

In my experience, of your profession.

Almost certainly.

My profession? Yes.

Did you know there'd been a ransom demand?

Did you know and didn't tell us?

A what? There's been a ransom demand from who?

I bet he knows, too.

Is that true?

And they're taunting the authorities from every fucking information board

in the country. What?!

You don't have any idea who this driver is?

I didn't say that.

The woman in the hotel...

..she gave me this.

PASSENGERS TALK OVER EACH OTHER

You've been sitting on this the whole time?

Get off! I'm telling you this.

Everybody get off!

Joe, one minute.

One minute.

Oh!

TRAIN SQUEAKS ON RAILS

It's going backwards.

Abby?

Abby? It's all right.

It's all right, Joe. It's...

It doesn't matter if it goes back and forth as much as it can.

They're like a rat in a sack thrashing around now.

It's OK, it's OK.

It doesn't matter which way we go. HE GROANS

Hey, hey. I'm not going backwards.

This ends now!

Fuck off! Get out the way!

Hey, what's going on?

Wait!

Stay away from me!

Wait! I need to get to that hospital.

There's nothing you can do.

There's nothing you can do.

Do you know something?

I don't know.

I don't know what the problem is.

They didn't say. She's in surgery.

Listen, I know how much you want to be there.

All right, I do.

I know how you feel.

I think I do.

Only reason I'm here is because of my kid, too.

Joe! Oh!

No! Wait, wait!

Oh, Jesus.

Oh!

FOOTSTEPS ON TOP OF TRAIN

Come on.

He's gonna try and stop it, Joe.

Joe? Abby.

The rigger's on the roof. He's trying to get to the engine.

No, no, it won't work.

Dead man's switch won't work.

The brakes won't work.

That's the whole point.

The train is no longer being driven from in there.

The single board computer in the manager's office -

THAT is the locomotive now.

It has a driver.

We just don't know who they are.

WIND HOWLS

ELECTRICITY CRACKLES

The key!

BRAKES SQUEAL

HE CRIES OUT

Ah!

Ah!

MOTOR RUNS

DANNY GROANS IN PAIN

Ah!

HE GROANS

HE STRAINS

I can't see it.

I can't see it.

Ah!

Ah!

Ah! Ah!

Ah!

SEVERAL RAPID BEEPS

What's happening?

The points, they're changing.

DIFFERENT PHONES RING AT ONCE

Yes.

North of England Signalling. They need to speak to you.

Abby Aysgarth.

We've lost control.

Sorry? We're now entirely locked out of everything.

It's not glitches.

It's...

It's gone.

Whatever it was they were trying to do, they've done it.

It isn't just the train any more.

It's the points, signals, all track-side comms - everything.

DANNY GROANS

Oh.

It's UK Rail's Gold command.

Is what's happening up north happening everywhere?

Yes.

DANNY GROANS

Ah!

BEEPING

Meg? Abs? DISTORTED: We regret that the 2345...

Part of...overnight.

Service from... Glasgow Central.

Is no longer arriving at London Euston.

DANNY GROANS

HE STRAINS FIERCELY

DANNY GROANS

WET SLICING

ANNOUNCER: We regret to inform you that the 2345 Heart of Britain

overnight service...

From Glasgow Central is no longer arriving at...

It's come off the loop.

Where's it going then?

Anywhere.

The entire UK rail network is now just a model railway

in someone's attic.

And now I know whose.

If you're the one with a phone that's still working,

can you speak up now, please?

Oh.

I think we should hack Miller.

Well, there'd be no way back.

If we don't try everything, we don't deserve one.

How are you going to deal with this?

Same as everyone else - not well.

GUNSHOT RINGS OUT WOMAN: Let me talk! Let me talk!
