I didn’t get all caught up in this buying craze, but I did look in a cupboard, and found that I had four of the replacement drives in stock.
They aren’t the ones with metal side rods, but they are the good motor and gears (Not metal). I have two locomotives with these drives in them, and they just keep running, and running and…
The drive with the so called “Simplefied” motion, does need some added parts to make it look correct. It is supposed to replicate a locomotive with Stephenson link motion…but lacks the wee bit of motion that should be there to be seen. All you need is a simple rod from the steam chest to a bell crank mounted on a rod running under the boiler…it needs this on both sides.
There are lots of pictures floating around on the web, to help anyone that cares to correct this missing machinery.
