Michael opens the case to reveal an ancient artifact. Michael goes to leave with the loot but Trevor wants to see it before it goes. Once out to sea, the heat has died down and the pair drive the dinghy to a nearby beach. Now more Merryweather guards are pursuing them on boats, Michael drives them away while Trevor takes out as many of the guards as he can.
When there's a window to escape, Trevor makes it over to the dinghy and the pair drive down the rapids. While Michael is unloading the take onto the dinghy, Trevor, who has made it to shore, defends him from ongoing heat from Merryweather. Michael puts sticky bombs on the doors and blows them open. Trevor tells Michael which container the take is in. As he gets to Raton Canyon Bridge, he sees the train Trevor is driving crash head-on into a train coming from the other direction, causing the cargo and train cars to fall into the river below and Trevor to jump to safety. Play them switches to Michael, who is driving a dinghy to the bridge from the Alamo Sea. Trevor drives the train straight past Paleto Bay Station, making Merryweather aware the train has been stolen. He drives to the front of the train, takes out the conductor and takes control. Trevor rides alongside the train and eventually uses a jump to drive the Sanchez on top of the train. The train is on the tracks to the east of Sandy Shores. Trevor heads towards to train on a Sanchez and tells Michael to meet him underneath Raton Canyon Bridge on a boat. Trevor tells Michael that the train, owned by Merryweather, holds enough gold to keep Ron in trailers, Michael in therapy and enough to pay off Madrazo to get the pair out of exile. As Michael is querying this, Trevor arrives home with Patricia. The pair talk for a bit before Ron tells Michael to tell Trevor about "the monthly train. A short while later, Ron appears, asking for Trevor's whereabouts. Michael heads to Trevor's trailer and relaxes. You don't need to obtain them all in one single playthrough.
