I do, and now my kids play with it.
As for my 1st electric train set, I still have it too. Here is the locomotive.
It's an old MARX that my grandpa fixed up and gave me. The tender and freight cars were all plastic, and over the years playing with it, most of them got all broken up. I still have them, but they are in a box. Just the locomotive is on display. I did find some tin cars on eBay a few years ago, and put them with it as you can see. It still runs, for a bit until it gets hot, then it slows down and stops. Once it cools down, it'll run again. So I don't run it often as it only takes it like 5 minutes to get to hot to run. That and the reverser sticks, mostly in reverse. I've had it looked at by a couple people and none have been able to keep the reverser from sticking. It's pretty old, and I did run it into the ground as a kid. I'll keep it until the day I die.
