In-universe, the one on the train is a print based on the long-lost original.

In reality, the team at DHX are saving money by reusing bits of background art. Heck, they're even reusing animation! That bit with the Shadow Pony at the end of the episode had cut-and-paste bits from Zecora's introduction in Bridle Gossip.
