I purchased a Large Scale Bachmann train set at a yard sale. It was advertised as an "Old Train Set." It is a 4-6-0 like #49 "The Ringmaster" on page 94 of the 2005 Bachmann catalog, except the paint scheme is different. It has a red cab and a silver & black boiler. It looks like all the large scales are the same 2-6-0 engine with different paint schemes, different smoke stacks, & different road names. This one was the AT&SF. It runs fine except it is awful noisy. Are they all like this or can I take it apart and lubricate it or something?
