Numb3rs

Tim,it's milepost 112-9.

Roger that. MP 112-9.

Dispatch,this is Desert Pacific Rail. Just passing MP 112-9.

We will be at the switch in five minutes.

Got you,Desert Pacific Rail. What's your speed?

We are highballing at 20.

What are you pulling?

10,000 tons of American ingenuity.

: All right.

I'll keep an eye on her.

Do you mind?

You have an audience.

Sorry. We're cool.

Thank you.

-Pretty soon,that'll be you with a pretty girl like that. -No way.

William,what's wrong?

Hey,can I ride up front with you?

Well,maybe on the return trip,okay?

You know you're not supposed to call me unless it's an emergency.

Okay,Dad.

The flag's not up.

-He didn't make the switch. -I know.

Dispatch,this is Desert Pacific Rail. Do you read me? Over.

We're not going to make it.

I can't get it stopped.

Dispatch,this is Desert Pacific Rail.Do you read me?

Jump,Tim.

-Dispatch... -Tim,jump!

Dispatch,San Jose Limited,coming your way.

Dispatch?

Young man...

I'm going to go see my dad.

You know you can't go up there when the train is moving.

-He said I could... -William.

I may be old,but I ain't stupid.

What's going on up there? What's on my track?

Stay in your seats! Hold on!

Come on!

Mom! William!

I got him!

I mean,when I started at the FBI,I figure,you know,I'm doing something good.

I'm fighting the fight.

It just sounds so...

old-fashioned. It just sounds so naive now.

No,no. It doesn't.

It's all just one big compromise.

I'm telling you. One big personality clash with redundant paperwork.

The boss is second-guessing every move,second-guessing their bosses, everyone just trying to keep their job.

Nobody's got any guts.

Yeah,well,you got guts.

I feel lost.

I feel like...

I don't know why I'm in it anymore.

Who's winning?

Actually,uh,I got to get out of here.

Yeah. Eppes.

I'm so tired,I could sleep standing up.

The stakeout was worth it.

I loved the look on that guy's face when we sashayed in there instead of that teenage girl.

We got two days away from the creeps. You goany plans?

Whatever sport is on TV.

Got a train crash.

-Call NTSB. -They called us.

Possible hazardous materials. High threat,urban area.

By hazardous materials,you mean old computer batteries?

No rest for the weary.

I want to know what was on every one of those trains, so e-mail me that waybill,ASAP.

Send it to my phone.

-You think we're dealing with anything toxic here? -Still checking.

We might have to evacuate the entire area. The press is going to be all over this.

LAPD's got 'em blocked off a mile away.

-Where do you guys need us? -What do you think?

-I could use the manpower. -You got it.

Why don't you go see if you can find the NTSB,and you go with him,all right?

Hey,I got her.

I got her. Let's go.

Easy,easy... easy.

-We're setting triage up over there. -Okay.I'll bring more over.

Anybody in there? Oh...

David!

-Anybody in here? -David!Get out of here!

-There are people inside... -We've got a toxic leak!

There's a toxic leak!

Everyone,get away from the train!

I have a press conference to do in ten minutes.

All right. So what do you need?

We've still got dozens more people to pl out.

We're going to have to go for the numbers.

Got to save as many lives as possible.

Listen,there are still passengers here in this car underneath the leaking tanker.

By t time we get to them,they'll be dead.

Look,let me just see what my guys can do,all right?

Over here! A problem!

Okay,so who knows what? Talk to me!

Sheriff's Department is evacuating a five-mile radius around the site.

Then you guys should go help FD with extractions on that tanker.

What's the chemical? What do we need to know?

Methyl isocyanate.

It's used in the manufacture of polyurethane foam,pesticides and plastics.

That's the same chemical that killed over 3,000 people in Bhopal,India.

It's basically a weapon. So how bad's the leak?

Well,if it's bad,we're all dead. Yeah.

Hazmat measured two parts per million-- not fatal.

If you start tearing up,or start to smell something sweet,

that indicates four parts per million,in which case,run.

But even small amounts could be lethal to the wounded people,right?

It's transported in liquid form.

When it hits the air,it vaporizes but,

with water,it overheats and combusts,releasing a toxic cloud.

We need to get those people out of here before this thing explodes.

-All right.Let's go. -You guys be careful.

So the black box is basically destroyed. It's not going to help us.

Trains are monitored by computer-- I'll get the electronic records from the company's hard drive.

See if you can find out who knew that cargo was toxic.

And dog the bomb squad until we know what set it off,right?

I need a list of all National Security events in the last 24 hours.

Are you thinking terrorism?

Go. Go.

Yeah,I'll hold.

Excuse me. Are you in charge?

We're not quite at the level of rogue,shape-shifting nanobots as described in science fiction.

However,we have made progress in the real world-- swarmbots.

Alone,unsophisticated machines.

But,working together,with something like... like intelligence emerging.

These are crash investigators.

Here. Check it out.

So I program a task for the swarm,right?

Let's say I'm mapping this room,and they try to accomplish the goal of that task.

Right now,they're self-organizing. They've chosen a leader.

See,some jobs need centralized control. Others require swarm activity.

Hey,Charlie,what happens if I shoot the leader?

They figure out who the next best leader is.

See that?

Look. They just keep going.

It's much more robust and cooperative in a hostile environment than people.

You're familiar with eusocial insects like bees and ants and termites.

Well,they communicate through pheromones-- scent clues.

Like,"I'm a larva. Take care of me.

Or,"Food's this way. " Or,"Danger! Attack!

" Following smells is called chemotaxis.

My bots employ infotaxis,which is a spatial search algorithm

in which agents repeatedly update guesses of an object's location.

Each bot creates a model of its local environment,

it networks it,and we get a collective picture.

-These things could map my crash? -That's what I'm saying.

I can reprogram them,I can add lipstick cameras and chemical sensors.

The switch wasn't right.

-We couldn't stop in time. -Why not?

It's a redundant system,but everything seemed to fail at once.

Cutty exerted the right amount of brake pressure for the tonnage, but the train just kept going.

Tell me about your engineer-- Cutty Nagim.

He wouldn't abandon the train,even though we were sitting on 2,000 tons of diesel.

-Did you recover the body? -Not yet.

What kind of name is Nagim?

Syrian,I think.

Did he have ties to Syria? Was he political?

I'm going to find all this out. You might as well just say what you know.

Cutty was born and raised in America.

You know what,Tim?

Maybe all the parts in your redundant system just happened to fail at the same time,

but that passenger train missed piercing a tanker carrying a lethal chemical by about ten feet.

Oh,that's just a matter of time,Agent.

Scary hazardous materials roll through L.A. every single day on 100-year-old tracks with rusty,unguarded switches.

It's a miracle it hasn't happened up to this point-- a miracle.

Stay put.

Hey,thanks for coming.

-Yeah,uh,so where should I set up? -In here.

-I'm downloading the railroad's electronic records. -Okay.

This is much worse than I thought. I don't knowf my bots can make a difference.

Charlie,the people we're going for are the lost causes.

Anything we can do for them is better than nothing.

Hey,what's the chemical count?

It's the same-- two parts per million,but they haven't located the leak yet.

How many we got in here?

Six remain that are still giving off body heat,but they're buried deep inside.

-Can I set up over here? -Yeah,sure,Charlie.

-Are these the,um... -The six still alive.

That's,uh,Estella,William Ramirez. They're the wife and son of the engineer.

Probably died in the initial fireball.

Frannie Driscoll,her daughter was rescued earlier.

And that's Doug Abbott,21. He's,uh,traveling with Susan Lang,19.

Jeffrey Knight,railroad steward. He has a radio,but it's dying.

Hey,Mr.Knight,this is Agent Granger again.How're you doing in ther

William and I are hanging in.

-I can't see the others. -My leg hurts!

You're a tough guy,right?

Where's my dad? Is he okay?

Hey,buddy,you dad wants you to be brave,okay?

You can do that,right?

-Radio's dead. -So can we get them out of there?

We're worried about destabilizing the wreckage,or worse,the tanker.

-Well,my bots should help with that. -How?

They're going to explore the debris.

They'll radio back information on toxicity,temperature,topography.

I'll add that to your infrared layout.

We'll get a detailed map,and we're going to get these people out of there safely.

All right,I think I can get to this one right here.

-Yeah? -I'm gonna go for it.

All right,Charlie.

What did the bomb squad say?
