I have the Play Gauge Polar Express and agree with you.
Sized a bit smaller than 1/32 & will run on gauge 1 track(or the floor if it derails). Extra track can be located and i've adapted other varieties of gauge 1 plastic track to meet up with the Lionel track.  If adding other manufacturers  large scale train cars to your consist, you will find the little wire ties off of bread bags work as a connector since the couplers will probably not fit together.
l have seen hacks where folks have adapted the loco to track power and/or adapted 9 volt rechargable pacs.
Happy Rails!
