I was gonna mark a time, but actually the first thing you see in the episode is the train. Though an interesting thing to note is that the train is being "towed" by horses as opposed to being self driven... so the argument about steam power could still be made I suppose.
Um... there was a train in the first season...
Over a Barrel they were delivering a tree to Applossa
