Hi, newbie to the forum here. Like many, I have recently expreienced a rebirth in model railroading. I've acquired a newTuscan red Pennsy GG1 that is waaaaay too fast, even on the slowest transformer setting. I have several other engines/brands that all work very well on my basic 4x8 oval layout. The transformer used is the 'ol standard Tyco gold box. At about 3 throttle clicks she gets power, about 6 clicks we have movement, and 8 clicks + we have derailment at the first turn! Even a big string of weighted cars won't hold it back much at all. This baby just flat out steps 'n fetches! Anyone else have this kind of trouble with (an engine)? I suppose a resistor could be put in the engine, but i'm no electrical engineer. Thoughts anyone? Thanks in advance, Pete
im not familiar with the IHC GG1 gearing but it may need running in, sometimes a good running in session will 'loosen' things up a bit and give you a slower working loco at low controller settings paul
MotoArts Welcome to TrainBoard! I would solder pairs of diodes to the motor leads. With DCC you can easy set the max speed via CV. Wolfgang
Probably would! The thing flies - literally. Anything past approx. 1/3rd throttle and it pitches off of an 18" radius curve. Unfortunately I don't have DCC, only the standard DC (so far). What diodes will I need? They'll work with DC?
lets call it the mad engeneer jr as i have the first a model power F7 Santa Fe and the mad steamer it takes off when it wants however it wants (model power quality for ya)
You can use simple diodes from Radio Shack (?) or so. They sell for cents, one type is !N4001 which can hold 1A. You need at least 8, 4 in line and the other 4 antiparallel in line to the first ones. Wolfgang
