Our grandkids loved playing with this set, but they have grown and we don't expect any more. Besides, I'm getting too old to crawl around on the floor helping with setup. This is all that's left of our collection. We have retired and downsized, so this and a lot of other things must go to new homes.
Most of the items are made by Mattel. A few were other brands. I tested the engines and I only found one that didn't work. If you've worked with these before, you know you have to finesse the batteries to make sure they all run perfectly. I did that testing about a year ago, so you may have to spend a little time as I did cleaning them up and making sure there was no oxidation. I think there are 12 engines with motors for running on the track. There are three smaller engines for display. They don't fit the track. Every kind of track and track length are included. You can see from the stack that there is enough for a large layout.Included are switches, elevated track, and a trestle. We didn't take the time to carefully inspect everything. All the track pieces look good.
