There is an achievement for sending XP on your international trains - it's under the PF4 train - you get the tail car for the maglev train for sending out 150,000 XP.

The electric locomotives give te XP cars a boost, the diesel and steam locomotives do not. The XP you get from each car only applies to that car, along with its boost - it does not apply to the whole train.
