Yes that is correct, but still the best outcome for the player are to send that XP train to 8 of his own contract, that way hw will get arund 60K XP.

And back to the question, if you don't have the needed XP wagons in storage they must be on a train at your station, maybe on the Macro Machines, or another train.
