I have an Atlas Item #6844-1 Providence & Worcester 3 Rail Powered Dash 8-39B Locomotive that doesn't want to run. I removed the shell to see if any of the electronics were burned and everything seemed fine, no burning smell. Sometimes it powers up starts to run then dies. I am running it conventional with a ZW-L transformer, I don't know where to start or who is good at repairing Atlas engines. Any help with what could be wrong and I appreciate any advice.
Thank you.
George
