I read a post where someone suggested putting shims under traction wheels of a 4-8-2 to help with pulling power - mine really needs the help and if anyone could give more info on the process and were to get the shims it would really be appreciated!!

I have an old 2-8-0 that I want to send in for repair or replacment - I think it must be replaced - what are my options for replacement and cost??

Also - I just purchased a new 2-6-6-2 and am not happy with the way it runs - poor at slow speed, wont pull much for as big as it is and it derails at switches - none of my other locos do - do I have a bad one or are these traits typical of the 2-6-6-2?? Is this loco discontinued? if so and I send in for replacement what are my options for a replacement??

Any help from the Bachman or others would be greatly appreciated!! thanks
