I recently got a Bachmann 35 ton two truck Shay.  Beautiful engine, didn't run right out of the box.  Three of the four gear were loose, which probably caused that.  It's such a nice engine, I would like to replace the current rucks with the new die cast #88999.  How difficult is this?  I have installe a sound system in one of my other steam locos, so i am at least somewhat  tecnically adept.  Any helpful hints would be appreciated.  Peter J.

I noticed three of the four gears on the trucks slip.  Not only does the engine not run well, but it also makes a rcket.  Is there any way to fix this?  Thanks, Peter J.  Bauer

I recently got a V & T 4-6-0 Mogul, which I am very pleased with, except that the sound is barely audible.  I have a new 9V alkaline batter in the tender, and the speaker swith is down (on) on the back of the cab.  Any suggestions?
