I would like to know if this train set is any good.
I believe the locomotive has the older Blue Box style motor, so no DCC, but the shells are good and it should run fine. As for the passenger cars, they should be just fine too.
Isn’t Athearn still using the old “blue box” F7 shell/body as well as the older style motor? It’s 1950’s tooling still for sale 50+ years later. If you don’t mind the looks of the older cruder shell on the F units then it may be fine for you. Keep in mind it still beats most traditional train sets.
