The engine has 6 large drive wheels and 4 small ones in front. the track measures 45mm between the rails. The coal car has a battery powered searchlight on it. It is in a box marked QVC. It looks like the original packaging, there are foam cutouts that the cars fit into. I would really like to get some CMSTP&P cars for this set, my Dad was a dispatcher.

I just purchased a fantastic train set but it has no instruction book and i don't know what gauge it is. The steam engine is approx 18" inches long from the cow catcher to the rear overhang of the cab roof, it has a number 12 on it. The coal car, box car, log carrier and caboose are all marked union pacific. The engine has a tag on it, says something about how to use smoke oil. Any help you can give me would be appreciated! Do you sell any box cars or other stuff that is marked Milwaukee Road?
