Reply to "MTH K4 engine derailing on Ross switch"

Dale,

Let's do some detective work.. You state that this K-4 derails on your Ross 042 switch- all switches? or just one? Looking at the locomotive by pulling up the product number it seems like the second set of wheels on the pilot truck is very close to the drive wheels. Check the spacing here with other steamers. Is it about the same space? or less? Next hold the engine in one hand, upside down and rotate the pilot truck. Do the wheels or frame of the pilot truck interfere with the locomotive frame or drive wheels? Next you could remove the pilot truck from the engine and run it through the switches.

What we are trying to do is find out if it is a problem with the switches or this particular locomotive. What do you find?
