|

I've seen the DCC mod some people have made to motors, and read about the overheating problem. Does DCC provide smooth DC to the motor or PWM? If it's PWM, the motor will heat up twice as much as usual. I once tried a 9V train motor with a 12V (...) (21 years ago, 2-Sep-03, to lugnet.trains)

Awesome looking crossing. I like the small size of the motors. What do you use to control this? I was in a hobby store last week looking at DCC stuff and they had crossing sensors for this sort of thing. Also, what happens with the gate is down? Do (...)

Thanks for the positive feedback. I think I like the red one better. I think it's the minimalist in me. But black seems to be a more traditional color. Now, who wants to trade me 10 black 2 x 2 radar dishes? I only have 2, so I had to swap them (...) (21 years ago, 2-Sep-03, to lugnet.org.us.indylug, lugnet.trains)

(...) I agree, very spiffy. Crossings get gates at various points in history, based on local grousing, the railroad's capital budget, the actual traffic observed at the crossing, federal or state highway funding etc etc so there's certainly lots of (...)
