So I recently picked up my first steamer, a Berkshire by MTH. It is the Nickel Plate 775 Unit. I haven't had any derailment problems with any engines or stock on my layout but this engine seems to be pretty finnekey when it comes to staying on the rails.
My main issue seems to be with the front truck coming off and then it seems to go down hill from there. Nothing seems to be turn related, they are all happening around switches. Is there something I am missing here?
