Not Sure, Is This Something New???

[Super]

The trailing car may be a luggage car.

It could be as it is an Airport train. It just looks weird because we are use to seeing the front and rear as the same engines. I couldn't see the rear car in the pictures of the real train that I saw. Now it would be interesting to see what it really is, eh? Hmmm, maybe all the cars are powered and it doesn't have to turn around...inquiring minds want to know.
