Wrong Side of the Tracks

"All we had to do, was follow the damn train, CJ!"

- Big Smoke to Carl Johnson if player fails in this mission, perhaps one of the most memorable lines throughout the entire GTA series.

Wrong Side of the Tracks is a mission in Grand Theft Auto: San Andreas, given to Carl Johnson by Big Smoke from his house in Idlewood.

Mission
Tenpenny and Pulaski are seen leaving Big Smoke's house by the garage. Carl arrives and Smoke tells him that they have to go to the train at Unity Station.

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 yellow 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.

Mission Objectives
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 .
 * You left Big Smoke behind go get him! (if Big Smoke falls off the Sanchez.)
 * Take Big Smoke back to his  house .

Trivia

 * If the player fails the mission by losing the train, Big Smoke will shout "All we had to do, was follow the damn train, CJ!". Due to the difficulty of the mission, leading to many players failing it multiple times, this line became very famous among fans of the Grand Theft Auto series, to the point of becoming an internet meme.
 * In the open-world sandbox game, there is a splash which reads "Follow the train, CJ!", which is a reference to this mission.
 * Even if the player kills the train driver before entering the red marker on Unity Station, the train will still depart from the station during the cutscene.
 * It is possible to use Big Smoke's Glendale to chase the Vagos, however this is not recommended as the Glendale can barely handle off/road well as the Sanchez and it is too big and it could be prone to being hit by a train if in a wrong area.
 * In the beta version, when chasing the train, CJ would complain that the bike wasn't built to take so much weight, and claimed that people don't call Big Smoke BIG Smoke for nothing, to which he angrily replies that he was born big, as seen in this video.
 * Also in the beta version, another objective would have been to retrieve a package from the dead Vagos, as seen in this video.
 * 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, Wrong Side of the Tracks.
 * 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.
 * The name of the mission may be based on the phrase "the wrong side of the tracks", meaning a poor area of a city.
 * 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 can't 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.
 * It is possible for the second and fourth Vagos from the front of the train to mysteriously die, leaving only the first and third to kill. If driving correctly, they can be killed before meeting the oncoming train in the tunnel. The player can see their guns land on the tracks if looking back quick enough (tested in PS4 version).
 * In , next to the dead body of JC and Little Smoke, the player can find dialogue that refers to dialogue in this mission.
 * During the chase segment after CJ and Big Smoke pass the red rail bridge, there is a Glendale driven by a driver which has the appearance of a Vagos member attempting to cross the rail tracks.
