From a design standpoint both wires could be black, or red or green, or polka dotted because the circuit polarity changes.
In fact, other non-train designers I know of would use two of the same color and stripe one just so the end to end continuity can be tested in one try..
I think red & black were only chosen to throw some clue towards the novice owner that those would be motor power going in..after all the motors are often marked this way too; but that is for directional orientation to poles more than reversing or non reversing applications.
Your train of course, but I why fret over colors without any real technical meaning.
Hopefully you get the last laugh and an increase in value pays for the effort and higher risks involved. But I would take the low risk easy route because the chance at increased value from this being "correct" are sooooo slim.
No grading guide exists on electronics the last I looked through TCA either.
Those solutions given ARE the answers, good luck deciding.
