Can you read what is on those black devices to the right and foreground in your picture?

Two of them have this printed on them: 2N 3904 - 006. The third to the left appears to have this: 7 MPS A14. That one is in the space marked on the board as Q3; the others are are in spaces Q1 and Q2.

I assume that this is some kind of constant voltage board. Possibly dumb question but what happens if I connect this to track power?

P.S. Motor is a Mabuchi but no serial number or other ID on it:
