Reply to "steam whistles"

I an using an MRC 130 watt transformer. (Bought it from a retired model railroader, so I don't know its age.) Tried various powers from 1/4 through to full. Barely any motor spin at low voltages with increasing, but not adequate whistling, at full. It's as if I need more voltage. Maybe I do need to bypass the gray resistor. It is labelled R31. It is soldered into the board. No idea how to bypass. Can you tell he how?

Thanks to all, Bob
