The gang will need to seek the use of a handcar to keep up with the very fast Iron Horse number 3 for the heist. The handcar is locked in a metal cage. Unfortunately, Murray's strength won't be enough to break it. Get two bear cubs to fight inside the cage so the mother will break it for them.
- Throw the cubs inside of the cage
Pick up each cub like any other object and carry them to the fence, marked by a waypoint. Avoid going near guards as the bear cub will make noise that alerts them. Throw both of them into the cage. Once both are inside, a cutscene will play. After it finishes the job is complete.
