For what it’s worth, I just tried to use the 022 voltage from binding post to power a train. At 15v, It was able to power a small dc can motor in a 4-4-2 8206 steamer. It did not have enough power to turn the motor of a 2026 postwar steam engine.
Better off using an actual relay. Right tool for the right job. My apologies for taking the thread down an incorrect path.
