Thanks everyone.
Just so you know: I am familiar with trains. I have a few Flyer and a lot of Lionel postwar and MPC.
Yes. The transformer is a Lionel TW. I never got to ask Dad why that was. . .
Also, the caboose had a (blue?) man that moved in with track power and back out when off. It was brown. Does that help identify the year?
The engine was stored in a brown, corrugated roll. The chug chug and smoke were awesome.
The rocket launcher car was a blast. Broke many rockets, and a few knick knacks trying to catch it!
We had a re-railer section of track.
I remember both yellow/blue and red/white boxes in Dad's storage box every Christmas.
