I was thinking recently about some ideas for the roller coaster track that TLG does. I do not own any of the track, but I have a feeling that TLG could make a new airport shuttle set using the Roller coaster track. The trains could be four studs with and be what’s called AGT, or Automated Guideway Transit, which is common in many airports. Although the Automated Guideway Transit set does not have to be specifically for an airport as the Miami Metromover in Miami, Florida, is an Automated Guideway Transit system. The ability to take tight curves could also benefit the sets as being easier to implement into existing LEGO cities since the roller coaster track is not as wide as regular track. the system could also be an elevated cable car like the one they have in Las Vegas at one of the hotel areas using the chains to pull the vehicles along level straight track. This provides some interesting possibilities for a series of transit based sets that I would like to see, and maybe even buy.
