I've had this issue with two parks now. in one park i built a go kart track with two station units and could only fit one kart, then when I rebuilt the track to extend the station, it still only allowed me to have one kart no matter what i did. I started a new game in another park and built a custom wooden coaster, when i went to test it, the train was 2 cars long and only had one train despite the fact that I made it a block sectioned coaster to fit more trains. Anyone else having this issue or know of a fix? Ive been trying different settings but nothing has worked so far.
