For those who wanted a bit more info
These are Goldlok trains (I have seen identical sets under the Fast Lane brand name). I own two different set:
-Western Express (Spirit of Steam)
-Passenger Express
The locos in my sets are a little different from each other (so I can confirm there is a bit of variety between those two sets at least).
Both come with an engine and 5 cars and enough track to build a 41" x 29" oval. Neither box has a product code or ID number. The bar code on both boxes is identical, so that's no help.
There were several other versions of this set that I know of, including:
-Continental Express (engine and 3 cars)
-Patriot Express (engine and 5 cars)
-Western Express (Christmas Express) (engine and 4 cars)
There are definitely other configurations. I have seen the same set (Western Express) packaged in several different ways (the types of cars changes, but there are usually only an engine plus 3 cars in these smaller sets). One version of the set comes with the standard engine plus 5 cars, but includes additional track (the oval mentioned above, plus two switches and some extra curves so you can make a circle inside the end of the oval.
So DO NOT just search for a set that says Western Express and think you are getting the "right" one. You may pay more and get less than you bargained for. Before you buy, make sure you see a photo of the set so you know if it's a small 3 car set or a larger 5 car set.
They are "not" 28mm trains. They are brightly colored (not painted, the plastic parts are molded in different colors) engines and cars, with black plastic track. The track is not bad actually. The wooden ties have a wood grain to them which a quick drybrushing would bring out, and the "rails" are shown spiked to the ties, a nice little detail). No scale is specified anywhere. The idea is you snap together the track, put a couple of batteries in the loco, switch it on and your train chug around the oval track. The loco makes train sounds, and the light on the front works. Apparently the various Christmas versions play tunes.
I found both of mine on ebay. Every now and then somebody will post that they saw a set at WalGreens, but one store may have them, others not.
I just checked, and here are a few on ebay:
You might get this one for cheap, but the shipping is on the steep side:

This is the exact Spirit of Steam set I have. The nice thing about the "larger" sets is that instead of just an oval, there are two switches and some extra curved track:

And if you want a brand new one from TrU here you go:

Yes, you can find them cheaper (or free, apparently) if you are willing to be patient and search high and low.
I found the above by entering "western express train" as the search term. I had no luck with "passenger express" or "patriot express". But next month, one of those might get a hit. They come and go.
Hope that helped.
