what's in *this* box? (that says "TRAIN" on it...)

Here is a *very pleasant* find today!! I haven't had time to really research it yet, but there's a LIONEL #318E "SUPER MOTOR" FOR STANDARD TRACK, a JEFFERSON ELECTRIC train transformer, a signal light pole, and a rheostat thingie for something -- all seemingly *very old* as such things go -- the transformer has a "light socket" screw-in 'plug' on it for heaven's sake, so for that alone I'm guessing 1920's or so...???

I'll update this when I get time to really find out about it, but in the meantime *anybody/everybody* is welcomed to leave a comment if you can give me a clue, or point me towards one, or ?? :-) :-) :-)
