How to make working train with multiple bogeys in unreal?

What I have done until now is made a tracks using spline and then made a train pawn which moves along the spline on player input. what I have not figured out is that how to make multiple bogeys that could follow the train along the track.
Any help would be appreciated
Thanks in advance!
