A group of robbers in the Old West (of America) are planning a daring heist. They intend to rob a newly commissioned train on its maiden trip across the country. This train will have an upper-class crowd celebrating the trip, along with a great deal of private security.
The plan is to pose as waiters in one of the dining cars until the train leaves populated areas, then rob as many wealthy patrons as possible and bail with the loot.
The issue is the speed of the train, and the likely death involved in jumping off it.
How can these robbers survive jumping off a train moving at 60mph?
Assume:
- The robbers are limited to what resources they can stow aboard the car(s) that they will be working.
- The loot will be cash and jewelry from the patrons, and will likely not add a great deal of weight/bulk.
- The method of bailing should be as independent as possible of the state of the train (except passing over water of course) so that the robbers can escape whenever they need to.
- Technology is limited to what is readily available in the eastern United States in the 1870s
