It appears Kmart is transitioning away from "Trackmaster" branded Thomas & Friends train sets to "Fisher Price" branded sets
The tracks I believe are compatible between both brands.
This puppy was $29 normal price, and has been replaced by a Fisher Price branded version @ $39

It is on clearance and is an instore item only.
Kmart's web site has stock availability but it is pretty flakey IMHO.
I don't know of a web site that shows all stores with stock but one of the geniuses here has probably made one - if there is such a thing please put a link in the comments as it would be super helpful.
60+ pieces. Assembling it in the pictured configuration will test your patience and engineering skills, but you can make simpler tracks.
no stock.
