- "There's a train that's gonna make an unscheduled stop down the way. It's got a, how do you say, little somethin' somethin' onboard for you boys."
- ― Frank Tenpenny
Carl pays another visit to Ryder, who is making his own "water" (marijuana dipped in embalming fluid and then laced with PCP) after he couldn't find it in his backyard. While Carl and Ryder are talking, Tenpenny and his accomplices drop by to inform the two that there will be an army munitions train passing through town shortly, and that enemy gangs such as the Ballas will attempt to raid the train.
The two immediately depart, arriving at the train only to find the Vagos have ambushed the train first and are attempting to offload munitions, while fighting the Grove Street boys. Once the Vagos are eliminated, the Ballas show up and attempt to take the train. Not wanting to lose the munitions, Carl jumps onto the train. Ryder promptly jumps into the back of his Picador, who waits with a GSF member driving behind the train, with Carl throwing some boxes to him. After acquiring a sufficient amount of munitions, the two are pursued by the police. They go to the nearby Pay 'n' Spray to lose the cops, and drive back to Ryder's home.
In order to complete the mission the player must:
- Drive Ryder's truck to the ammo train.
- Shoot the Vagos robbing the train.
- Protect the train from the Ballas.
- Climb onto the back of the train.
- Toss the munitions boxes to Ryder.
- Use the nearby pay 'n' spray to lose the cops.
- Take the crates back to Grove Street.
- Tenpenny jokes that his "wife loves" the type of drugs Ryder is making, but as CJ will see later in the Body Harvest mission, Tenpenny is the one using drugs.
- The song heard in the pre-mission cutscene is Fantastic Voyage by Lakeside. This song can also be heard on Bounce FM.
- When Tenpenny and Pulaski enter the kitchen, no one is behind them, then the next second, Hernandez is suddenly behind them.
- Also, during the cutscene, CJ disappears for a few seconds and reappears again when Tenpenny informs him and Ryder of the ammo train.
