does it have a white motor?

No idea about the 1977 era.

I suspect below is what you might have. Many of the 4-8-4 design had the pancake motor which is not very good, over time. I believe all where three pole motors. They were essentially toyish type locos. Some included a smoke generator.
There was also a line of Bachmann 4-8-4 that had a can type motor and smoke unit.

There are a few more diagrams at the HO Seeker site for the Bachmann locos.
