I recently made a Lionel Fast track addition to my layout. I use MTH's Z-1000 to power this track. I warmed up a PS-2 BMT Standard subway consist setting the power to about 1/3 power. The train ran well but after a couple of minutes I began to smell smoke, electrical. I stopped the train and turned everything off. I pulled up the power track to discover that the connecting wires and plastic of the roadbed began to melt slightly. Why would this occur?
