I did look at it; I don't see a small slot, but an open space that looks like it could accommodate the tender. I'll give it a shot, thank you!

There's nothing on the back of the locomotive to even attach a bread tie to.

I received the Norman Rockwell Christmas train set as a gift a few years ago and now have space to put it around tree. The locomotive has no way to attach other cars and none of the other cars attach to each other easily. Right now the locomotive is traveling around by itself and the other cars are looking like they are in an abandoned train yard. Can this be fixed?
