Its Here

Leaving DC locos sitting on a DCC layout is a bad idea and running them for extended periods of time could hypothetically cause problems, but I have never had a problem, however a by product is that humming noise and there isn't anything you can do to get rid of it short of converting your DC locos to DCC. Basically whatever you do, do not leave DC locos on live track for more than a minute or you could ruin them.

So far the only side effect has been that hum Converting the non DCC ready cheaper locos is probably not practical for me.  Instead I plan on buying a second DCC equipped Geep (and a small DCC Switcher for my staging yard).  Then I'll retire the DC Locos to the Christmas tree in 2011.  We will not be putting up a Christmas/Hanukkah layout this year, as our wedding date is 1/8/11 and its just too close to fuss with decorating.

Anyway I do not leave the DC locos on the track idling I take them off.
