Original subtitles

2 Joe?

[Abby] Joe?

[Paul] RTV's showing trains still moving.

[Saj] Then why aren't they responding?

[Miller] We all heard the collision.

Abby.

The comms plane's reported back.

I'm not sure the person who installed that device

is in the waiting room at Motherwell.

What?

[electric crackling]

[blowing heard through phone]

Joe?

Yeah.

Yeah, I'm here.

[gasps]

Oh, my God.

[Joe] You all right?

[grunting and groaning]

Am I okay?

The comms plane is showing that there are two phone jammers down there

blocking out 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 SBC isn't at Motherwell?

It doesn't.

This does.

[tense music plays]

[glass crunching]

You all right?

Let me find something for that.

[woman] Hey, hey, sit down, sit down here.

- Whoa! - I've got it, I've got it.

- Take this. - Thanks. I got it.

What just happened?

Goods train was blocking the line. They moved it.

You think they could move it earlier next time?

They know what they're doing,

and they do want me to help 'em.

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

I spoke to them.

He's telling the truth, okay?

We're never getting off. Are we?

I'm bloody getting off!

No, 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?

[Abby] Is everyone okay, Joe?

Everyone's alive.

A bit battered, but alive.

[sighs] Okay.

All right. Listen, erm,

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 over-scene intel.

But it's 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?

[Abby] One of the passengers

maybe working with the hackers.

Hey! She's talking to you.

What are they saying?

They just said we need to stay calm.

Everything's gonna be okay.

[laughs]

Right?

Abby.

I found a firearm.

What?

When we were looking for the jammers.

[Abby] Shit.

Did you move it?

The important bit.

What are you gonna do?

Watch.

Look.

Whoever's behind this

has hacked into the station information boards

requested a ransom, and calling themselves "The Driver".

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

So, has someone on there been recruited by them, or by someone else entirely?

[Joe] Why would anyone stay on board?

[Abby] I don't know any more than you.

But I'm worried we're about to find out.

Don't trust anyone.

[theme music playing]

I'll forward the names through to uniform as soon

- as they come through, yeah? - [Abby] Yeah.

[Saj] Should I try and get the thumbnail profiles

from the open source?

I could chase the CCTV up

from the hotel in Glasgow too.

- Yep, listening. - [Saj] And what about

digging into the Tehran group, looking for connections?

[screen chimes]

[dialogue inaudible]

- [Saj] You're on mute, sir. - [Zed] BBC News on the line.

They're asking if reports of a train derailment

and explosion at Gretna

are connected to the cyber-attack 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.

- [Leon] Abby. - Abby?

[Leon] Police helicopter?

- Abigail. - [Zed] Ma'am, press?

The answer is no!

[Hud] Message from the Home Office.

"Prove France wrong. "

Show that there isn't any risk out there

that our cyber security team can't deal with.

[Miller] Tell me that's true, Abby.

Because I have to give COBRA

an update in 12 minutes and...

It's not working.

I wouldn't worry about it.

[Billy] What's that?

Er, I got this on my my first day.

I was a guard back then, you know.

And then a few years later they says,

"No, it's wristwatches, you've gotta give them back," you know. But I didn't.

Never dropped a second.

I'm Chrissy.

Yas.

Thank you.

Hey, you helped me, didn't you? When everyone else ran.

Unlike you, eh?

All this... therapy,

fresh start, qualifications.

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

Fraser, I'm only gonna say this once.

- Oh, here we go. - Shut up.

- I can see it coming a mile off. - [Sophie] Shut up, shut up!

- [Fraser] Here we go. - [yelling] Shut up!

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

Like my dad.

[phone beeping]

[banging on door]

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...

My wife is in labour.

At the UCH in London.

And the thing is, she has preeclampsia,

and this liver thing.

Which means it's been really difficult.

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

Ah, 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?

There isn't one.

There isn't one.

Look, 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.

Boy.

Were you there?

When he was born?

They'll know you, you know, already.

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

Don't worry about that.

Now, can you help me with the jammers?

Aye.

Good man.

Come on.

It's not a weakness. The way you feel.

You'd have to be psychotic not to feel it.

I'm fine.

Well, you look like shite.

[scoffs]

I know it's been a while, 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.

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 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."

[sighs, laughs]

Okay.

[sniffles]

I was sorry to hear about him.

[sighs]

[sirens blaring]

Why would anyone with any amount of involvement

stay on that train, Pev?

From Glasgow, okay. But Motherwell?

Can't answer that one.

Let's just say that it'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?

[Joe] Abby.

- Abby. - Yeah?

The oil rigger has a situation with his wife.

Can someone there contact the hospital for me?

Yeah. Tobe.

[tense music plays]

Why are some of the lines dotted?

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

Okay.

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.

[Miller] Why?

Well, I want assurance from them, and you,

that they'll do whatever I say.

Yeah, UCH. Thanks.

[phone beeps]

[sighing heavily]

[music intensifies]

Got it, yeah.

UK Rail Gold Command, signalling control.

- Hi, this is Abby Aysgarth again. - [signalling controller] Yes.

I need you to take the nine 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,

the train's almost there.

Maybe 30 minutes.

[Miller] Abby, what are you doing?

[signalling controller] Carnforth, before it can switch.

Do it now, please.

Just cleared the WCM of traffic.

It has to be now.

It's going too fast.

- [Abby] Do it now. - [signalling controller] Look,

even if I wanted to,

I don't have the authority.

[Abby] Ma'am.

- What are you doing? - I...

I can't breathe in here.

Here.

No.

[tense music plays]

[machine beeping]

What the fuck is going on?

Are you sure about this?

[Abby] Yes. Do it now.

[train brakes screeching]

[passengers screaming]

[computer beeping]

What have you done?

[passengers grunting]

[Joe] Is everyone all right?

Did we hit something again?

Dear God.

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? - [Joe] Mouse?

My screen's cracked.

[Joe] Come here, mate.

This isn't the West Coast Mainline.

What is it then?

[train powers up]

[hopeful music playing]

- Okay. - [phone beeping]

[gasps] Yes.

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

Where are we?

You... [chuckling]

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.

[Joe] And the train? What happened?

The lights, the noise.

Yeah, this one isn't electrified.

So, how are we still moving?

The diesel back-ups kicked in.

So, if we take you onto the freight line further south,

we'll be able to put you on a loop.

- 'Til the diesel runs out. - Yes, 'til 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.

And so what if someone else is controlling the train?

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

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

Do you wait until the diesel runs out to remove the "acting",

or are you gonna do it now?

Get Gold Command to remove all passengers

and goods trains on any route.

Yeah.

Abby, I've had a glass of wine,

after champs and a serious surge of hormones

but I think I love you.

[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 TIC...

TOC. Train Operating Company.

[Leon] And FOC and ROSCOs.

Basic error on the firmware on the PLC.

They couldn't patch it with the software

because the scheme was physically burnt

onto a dedicated crypto authentication chip.

[Hud] Please, please use the English bloody language.

[Paul] 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?

[knocking on desk]

Uniform are currently kicking doors down

of everyone still on board.

But we only use the backdoors.

And we don't kick in, we log in.

Get North York's police out to the line

and track the train as closely as possible.

And get armed forces to reassess

an aerial landing once it's crossed

- the viaduct and is on the loop. - What did I just s...

- Nice one, Abby. - Thank you, ma'am.

[Tobi] Erm...

The oil rigger.

- Abby. - [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 could try.

- Did she give a reason? - No.

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

Yeah?

Sky Geoghan, the oil rigger's wife?

She's in emergency surgery.

The hospital say that the situation for mother

and child is critical.

Sorry.

But they're gonna update us within the hour,

should be clearer then.

What happened?

Yeah, thank you.

Er, they brought us off the mainline

away from the electrics.

Put us onto a loop.

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

So, we're just gonna go round and round? For hours?

Have you heard anything?

Have they managed to speak to the hospital?

Not yet, mate.

I'm sure they will soon.

Have you seen that girl yet? The one with the headphones?

[bangs the wall]

[Saj] So, we have Daniel Geoghan.

He's an oil rigger at Finnis Brae.

Twice fined for affray

and 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. - [Paul laughs]

[Saj] And then there's the staff.

William Billy McLeod. He's worked on there for nine years.

No social media. No profile.

No digital footprint. At all.

And Yasmin Brown,

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.

[chuckles] That'll be about right.

Possible financial motive?

Yes, er, which may also be true of Sophie Warren.

Now, she's currently studying for a PGCert in counselling.

It 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.

[clock ticking]

His son was left at Motherwell.

Says he's suffering from heart failure.

Well, if he wasn't before...

Er, and that leaves...

[Saj] Eleven-year-old boy, who we've discounted.

So Rachel Li.

Digital lifestyle trends reporter.

Arran Moy. He's a senior accountant

at Leagram-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.

[music intensifies]

Can I have a word?

About?

Just about why exactly you threw your bag out of that window.

[sighs] Hello?

[Tobi] Come on...

Ah, hello.

Huh.

Ha! Got her! I...

I don't know what you're talking about. Weirdo.

[Joe] I just saw you.

Are you okay? - No, no. I'm not.

[Tobi] The woman with the baby, she's with the passenger.

All right.

Now, watch.

Hey. Wait. Wait.

- Get off me. - What are you doing?

[Saj] What's she doing?

[Abby] Wait, wait. There's someone else there.

Get the footage from that camera.

[music intensifies]

- [Billy] What're you doing? - What's going on?

- [Abby] Joe. - [Erin] Let go, 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 with each other for about ten minutes,

and they took something from them.

Yeah, it's okay. I'm with her now.

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

- [clamour] - Joe?

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

You don't understand.

Someone on here is part of this.

- [Abby] Joe? - [breathing heavily]

Joe?

[heavy breathing over phone]

Joe?

Joe, did you...

[line disconnects]

- 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.

Open up!

[helicopter whirring]

We have optics.

This is November-Charlie One. Over.

[NPAS control] November-Charlie One, this is Alpha-Lima Seven. Over.

How close can your team get? Over.

It's gonna vary a lot.

They need to stay clear of tunnels, bridges, trees,

and it's currently accelerating significantly. Over.

It is?

[music intensifies]

[Mouse] Joe.

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

She's talking to you.

Hey!

The points 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.

Well, what is it for them?

Depends how curvy the track is. Not much above 100.

Hit a crack in 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.

I can only be certain if the train crosses it.

[tense music plays]

Hey, don't ignore...

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

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

What are you talking about? If it wasn't for him...

- [Sophie] What is that for? - What are you doing?

Oh, my God.

Oh, my God.

[Abby] 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 on board

and we're growing increasingly concerned,

and it would really help if we could get eyes into the carriages. Over.

[tense music plays]

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

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

Move.

Right, listen up.

Is that an axe?

Okay?

[Danny] Okay.

[train brakes screeching]

[passengers screaming]

What's happening?

Why have we stopped?

It's the north. Delays are inevitable.

No, no, this'll be us.

This'll be us. It's over.

Shit.

It doesn't look over.

You hurt, mate?

I'm all right, but the lady isn't.

- Which lady? - The lady in the wheelchair.

- Show me. - [Mouse] She's bleeding.

[beeping]

How do you open the door?

Have you seen where we are?

If you ever shout at me again...

Unless the driver releases it, it needs a key.

There. The staff will have one.

[door creaking]

[NAPS control] November-Charlie One, this is Alpha-Lima Seven.

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

[Miller] Alpha-Lima Seven,

this is November-Charlie one. Why? Over.

North York's Police look like they're gonna be late to the party.

We've been instructed to set down

two of our team as close

to the viaduct as we can.

I'd say we can have them on board

in seven to eight minutes. Over.

[Miller] Thank you, Alpha-Lima Seven. Out.

[helicopter whirring]

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

[Joe] What?

Have there been any messages for me?

Do you really trust the government

to tell the truth about what's happening here?

[Liz] 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 wanna 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?

- [phone rings] - 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 gonna be on the train in five minutes.

This is almost over.

Anything?

No.

I served you.

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?

[Abby] Joe?

[tense music plays]

Yes.

I knew it! I knew it!

[overlapping chatter]

Abs.

Three minutes, Joe.

- [Arran shouts] - [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.

Or seemed to be.

Continue.

I was contacted anonymously a week ago.

She said there was going to be an incident.

Incident?

On the Heart of Britain,

travelling form 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 wanna aggregate news,

write shit puff pieces

and copy and paste promotions.

I wanna 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 gonna happen.

- Not exactly. - You knew something was.

Something but...

You risked our lives for a career boost!

If I'd known anything like this was gonna happen,

I'd have hardly got on board myself, would I?

In my experience of your profession,

almost certainly.

Oh, my profession?

Yes.

Did you know there's been a ransom demand?

Did you know and didn't tell us?

- A what? - A ransom demand from who?

But 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 clamouring]

And you've been sitting on this the whole time?

- Get off! - She's in on it.

Everybody get off!

Joe, one minute.

- One minute. - [train jerks]

[sinister music plays]

It's going backwards.

- [arguing continues] - Abby?

- Abby? - It's all right. It's all right, Joe.

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 okay, it's okay.

It doesn't matter which way we go.

- Hey. - We are not going backwards.

This ends now.

Move! Move! Fuck off, get out the way!

What is going on?

[Joe] Wait.

- [Danny] Stay away from me. - [Joe] Wait. 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.

But she's in surgery.

Listen, I know how much you wanna be there, all right? I do.

I know how you feel.

I think I do.

The only reason I'm on here is 'cause of my kid too.

Ugh!

[Mouse] Joe!

No! Wait, wait.

Jesus!

Oh.

[footsteps]

He's going to the locomotive! He's gonna try and stop it, Joe!

- [Abby] Joe? - Abby, the rigger's on the roof.

He's trying to get to the engine.

No. It won't work.

The 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.

[grunting]

[wind whistling]

[electrical crackling]

Shit.

The key!

[grunting]

[train brakes screeching]

[shouting]

[grunting and groaning]

Ah. Fuck.

[groaning]

[Billy] I can't see it. I can't see it!

[groaning]

Ahh!

Ugh!

[breathing heavily]

- [computer beeping] - [Miller] What's happening?

[Saj] The points. They're... they're changing.

- [computer beeping] - [phone ringing]

[Saj] Yes?

North of England Signalling, they need to speak to you.

Abby Aysgarth.

[woman on phone] 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 anymore.

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

Everything.

[metal clanging]

[tense music plays]

[Tobi] It's UK Rail's Gold Command.

[computer beeping]

Is what's happening up north happening everywhere?

[man on phone] Yes.

[groaning, screaming]

[machine beeping]

[train engine starting]

[phone ringing]

- Meg? - Abs.

[male announcer] We regret to inform you that the...

[female announcer] 23:45...

[male announcer] Heart of Britain overnight service from...

[female announcer] Glasgow Central ...

[male announcer] is no longer arriving at London Euston.

[grunting and yelling]

- [yelling] - [squelching]

[announcer] We regret to inform you that the 23:45

Heart of Britain overnight service ...

From Glasgow Central is no longer arriving at...

[Saj] It's come off the loop.

[Miller] Where's it going, then?

Anywhere.

[theme music playing]
