Saw this in the flesh at Salute and was very impressed...will take very little work/filling to take it up a notch as a model...couldn't figure out what "scale" they are...they just looked good...and right...the pieces,to my eye at least,are smaller than O gauge but make up an impressive length unit when all latched together with the carriage roofs all being detachable making them effective gaming pieces as opposed to just eye candy...and with the points/switches also available a good looking track section can be accomplished...
....just wish I'd snapped a photo of a figure next to them
