Yeah, I wondered about that - the main hall design doesn't match the plan and is much closer to the Dutton Drive turnaround than would be possible if the track configuration was like that.
I've spent many nights looking at Google Maps satellite views of train maintenance facilities all over the world (but mostly Japan).
A lot of them do incorporate a way to run a train in a complete loop almost as a mini "test track". My favourite one (and I've been there several times, to tour the facilities and go for rides) is the Morgantown PRT In Morgantown, West Virginia. It's the wackiest system you can imagine.
