When the pair arrive, Smoke explains that the Vagos and San Fierro Rifa are "cutting some kind of deal," and intends to crash the meeting. However, it is actually an ambush and the Vagos attempt to escape by train. Carl and Smoke use a Sanchez parked nearby, to chase down the train to kill all four Vagos thugs, whilst avoiding obstacles such as; oncoming car blocks and incoming trains going the opposite direction. If successful, Carl and Smoke will have eliminated all Vagos before the train reaches the Frederick Bridge, connecting Los Santos and Las Venturas. The two then clear the scene, and CJ takes Big Smoke back to his house.
In order to complete the mission the player must:
Drive to Unity Station.
Get on the motorbike with Big Smoke, chase down the Vagos gang members and take them out.
Keep up with the front carriage of the train so Big Smoke can shoot the Vagos gang members.
San Fierro? I thought Northern Mexicans don't mix with Los Santos esses.
Shit, you got me.
*They notice some Vagos members above the tunnel* That look like them!
*Vagos jump on the roof of the train* Motherfuckers clocked us! We got to get those fools!
CJ and Big Smoke jump on nearby Sanchez and chase the train.
Follow that train! Get me close, CJ. I'm about to pop these fools. Roll up on them CJ, so I can get a shot! Oh fuck! An on-coming train! Take the high road on the right, CJ! Look the fuck out, CJ! The train! Move this shit, man I'm gonna ice these fools, man.
Big Smoke kills all Vagos members on the top of the train.
Hey, let's get outta here before cops show, man.
Was it always like this?
Was what always like this?
Always fucked up around here. Or is it because of the drugs?
What you think, man?
I don't know. That's why I'm asking you.
Yo, eh eh, don't ask a wise man, friend. Ask a fool.
That's what I was doing.
Well, if you're going to make this thing personal, I ain't speaking on it no more.
CJ drives Big Smoke back to his house.
Hey, you better clear out, CJ. I don't want those C.R.A.S.H. fools trying to pull you into some shit!
Alright, homie. You be careful with those cats. I'm gonna see you later.
Do not waste bullets trying to shoot the gang members, as the train is too high for the player to inflict any damage against them.
The best location to chase the train from is the far-right of the adjacent track, because if the bike is too close to the train, Smoke will shoot at the train and if it is too far away, his aim will be poor.
Just above the storm drain that the train passes, there is a ramp that is level with the train, and can be used to drive the bike on top of it. Not only does this give Smoke an easy shot at the Vagos, the player can also shoot at the gang members, assuming that they have a drive-by weapon such as a TEC-9.
Do not attempt to dismount the motorbike and shoot at the Vagos on foot, as the train is travelling too fast and the mission will fail if the player falls too far away from the train.
An easy way to complete this mission is to get a sniper rifle with at least 20 rounds, go far enough ahead of the train, get off the bike and kill the engineer so the train will stop and kill the Vagos. Note: Once you kill the train driver, don't get too close to the train or it will start driving by itself.
Another way to complete the mission, is to follow the road that runs parallel to the railway line. Turn the corner and keep going until you get to the Well Stacked Pizza Co, turn left and head down the road until you see an apartment block on your right. Stop near the wall and get off your bike, then jump up onto the platform next to the railway tracks. Get the fastest weapon you have and shoot the Vagos as the train rounds the curve. This also convenient when the mission ends and you have to take Big Smoke home again.

If the player fails the mission, Big Smoke will shout "All we had to do, was follow the damn train, CJ!". This line has become very famous among fans of the Grand Theft Auto series, to the point of becoming an internet meme.
In the open-world sandbox game Minecraft, there is a splash which reads "Follow the train, CJ!".
In the beta version, another objective would have been to retrieve a package from the dead Vagos.
This is one of the first missions to take Carl out of Los Santos and into Red County.
If the player abandons the Sanchez after killing the Vagos, it will still appear in the mission's final cutscene.
Strangely, if the player fails the mission just as the Vagos crosses the bridge and looks closely, the player will see that the train will pass through a barrier as if it weren't there.
There is a scene in Rockstar's Manhunt with the same title.
This mission is referenced in the Gold-medal objectives for the Grand Theft Auto V mission Derailed, where the player has to follow a train on a dirt bike. If they manage to land on top of the train on their first attempt, they will achieve the "Better Than CJ" objective.
If the player fails the mission within close proximity of the moving train, all of the Vagos on top of it will become invisible. Their weapons will remain visible. The first three Vagos will be explosion-proof. The fourth Vago is fully-immune, and cannot be killed.
If the player manages to kill all the Vagos before the train hits the broken down Glendale, the car will not explode when the train hits it as scripted and will simply be pushed away by the train.
