Here is a cool little article from Wired on how one starts a train by first backing it up so all the coupling are loose. The TL:DR version is that the static friction is greater than the kinetic friction. Thus, there needs to be slack between each carriage so that the engine only breaks the static friction one carriage at a time. Otherwise it cannot get the training moving.
