Fantastic Knock-Off Bridge

[Super]

I wondered the same thing. The track bows up in the middle because the electricals and battery compartment are under there. I like this idea better than making the whole thing thick, big and bulkier and the need to use some type of short riser to get on to it.. Keep in mind that this is not a "Thomas item" but copy cat. This did come in a set and I will see if I can find a link showing it.
