What is the Airport Shuttle logo meant to symbolize? The Airport Shuttle set features what is apparently supposed to be a logo of the Airport Shuttle monorail system, both on the train itself and prominently on top of the city stop (and possibly in more places). It looks like a capital letter T in front of a circle.



Is there any information available as to what this was meant to signify? I.e. is it meant to symbolize anything about the set (a cross-section of the airport stop?), or is it modeled after a real-world symbol of a comparable transportation system?
First of all, here's a slightly enhanced, upclose image of the logo.

My best guess is that it's meant to represent a railway T-Intersection as seen below.


I believe this is especially possible, considering how the T tapers down to the bottom, similar to a railway T-Intersection.
