I will chime in because I have recent experience with a PS1 purchase. I bought a Canadian Pacific GP30 #8202 from '95, because I like that road and it was a good deal. I run a Cab-1/Command set with a TPC 400.
Following advice, I installed a new battery. Didn't matter, I couldn't consistently get it out of neutral. I read some more and learned that these early PS1 engines are fussier than those from '97-up. Not running TMCC or DCS, I installed a Dallee reverse unit, which works perfectly.
Some points to keep in mind:
- The factory headlights run off the PS1 board. I like my engines to NOT have constant-brightness lighting. The factory light bulbs can't handle full voltage direct from the third rail, so be prepared to install new ones if you go this route.
- This engine is surprisingly fast and sensitive to small variations in track grade and voltage drop. I think I've gotten spoiled by "cruise control," but honestly, even my old MPC/LTI engines are less twitchy. I intend to rewire the motors in series rather than parallel.
- All in all, I'm not in a hurry to buy another PS1 unit...unless I find #8200 or 01 for $100 or less, because a pair would look awesome.
My $.02,
Alan
