Corrected entry: Several times during the train sequences, and on the schematics, we see there is only one track between the Mansion and the Hive. So on the return journey, the train should be travelling backwards, yet it is going forwards with Kaplan in the cab on both occasions. From the interior and exterior shots, you can see that it does not have a cab at both ends.

Correction: We never get to see EVERYTHING inside the Mansion and the Hive. Maybe there's a sort of extra part to the station(s) where the train can turn around.
