I am in need of the Middle Drive shaft for my 55 Ton Three Truck Shay. Bachmann Trains is out of stock and has been for sometime. I have talked to the manager or the parts department and he confirmed Bachmann is sold out of the part. Without a new drive shaft my shay is worthless. Is there anyone who has this part and is willing to sell it to me? Or, is there anyone who can tell me how to repair the part. The gears on the drive shaft are not tight on the shaft so therefore will not engage and turn the drive wheels. George Zoske in Arizona [email protected]
