Reply to "Tmc fan on smoke unit not working"

Ron, another reason for the reading below 5v is the fan is stuck. That can happen if its hitting the case. Then the motor will draw its stall current which is likely more than the 100ma rating of the regulator. BTW LM78L05s are dirt cheap on Amazon and eBay. Much less than just the shipping from Lionel.
