yep you can but it's tricky. the station in the middle of the three must be 2 or 3 squares longer than the other 2... and stick out the back end. the entrance and exit must be on the last squares of that station on opposite sides... and the 2 coasters on each side must dive down 2 levels under the middle stations entrance and exit... then shoot up to their respective stations.
sorry that was confusing.
