Currently my home layout is DC operated and utilizes Peco code 55 Electrofrog switches .. which I purchased to ensure operation of short wheel based steam loco's (e.g., 0-4-0's). However, I would like to be able to operate my layout as either DC or DCC; and while I do know what to do to switch operation from DC to DCC, what I am NOT sure of is how DCC will impact operation of Peco Electrofrog switches. Why? And what must be done to ensure proper operation in either mode (DC/DCC)?
I don't know the ins and outs, but here: http://www.wiringfordcc.com/switches.htm and here: http://www.wiringfordcc.com/switches_peco.htm should tell you more than you ever wanted to know! Jeff
If they work with DC, they will work with DCC. The 'wiring for DCC" links previously posted have tons of info to prevent or solve problems. The biggest problem with DCC is that a short circuit is detected and the breaker cuts out immediately. That same short occurs with DC power as except the protection is slow enough that many short circuits will clear before the DC equipment has time to react. My own experience is that properly installed electrofrogs will work more reliably than insulfrogs on DCC. This is due to the fact that the frogs need to be gapped on electrofrogs. This removes one of the common short circuit problems because both frog rails are the same polarity (phase in DCC). Best advice is to hook up the DCC, make sure the wheels are guaged properly and try it out. If a problem spot is found, then look for ways to make adjustments. Martin Myers
