@Sean's Train Depot posted:Thanks Sid, so what is a chain file? Do you use the MTH loader program to load this file? And where do you get it?
I will look for a loose wire connection first.
Thanks!
The chain file is the coding for PS3 locomotives. It is loaded using the MTH loader software. You can find the chain files on the MTH website under the service tab for the engine you are looking at.
