Locomotion was started as a successor to Transport Tycoon, but then Chris got distracted with the Roller Coaster Tycoon series.
He later went back to Locomotion and used the RCT2 engine for it.
It wasn’t very well received, apparently reviews thought it was too old-looking and old-playing for its time.
Chris did almost all the work on the game. The graphics are by Simon Foster who did the art in the earlier TT and RCT games too. Music was mostly by Allister Brimble who has game music credits a mile long.
