Reply to "Smoking Cabooses"

I have a k-line virginian caboose that has a switch in it to regulate the incoming voltage depending on whether you have command or conventional power. One day after setting the switch to "command" the electronics gave out and the roof and wall of the caboose melted.  From then on I don't run smoke in any car or engine.  Too much of a risk in melting $400 plus locos or cars.
