It will be interesting to see how close your project sound will come to this. A variable resistor or pot on the PS-1 motor may better help find the sweet spot then a fixed resistance.
Right. I'm not going to be terribly worried about the sync because PS1 was never really capable of perfect sync anyway. Plus, with this being an articulated loco, it's too hard to watch the wheels and smoke and see if the "beats" match, which was one reason why I never used to mind PS1 articulated locos. There's so much happening at once - it blends better.
One thing I do see as a potential nightmare is altering the chuff rate without a loco to watch going around the track - but I'll have to trial and error on that one until I get it close. Guessing, more than likely I'll have to adjust the chuff start voltage upwards (around 8-9v) as PS2 engines don't get moving steadily usually until about 9-10v.
First I need to find an old Yellow UP Premier water tender with proto-coupler because doing this to a boxcar is making me cringe more and more. If anyone knows of one or wants to sell a UP aux tender, email me. Thanks.
