Dave Zucal posted:I would advise to be very careful, when running a steam engine up side down, to clean the wheels. Some linkage designs will bend or lock up the wheels, which could fry the board. I usually use a clean Q-Tip to reach between the chassis and the shell to rotate the fly wheel and re-position the drivers for cleaning.
The locos that I mentioned by running upside down are the per ware electric loco's 150 series. 250 series and the 240. all of which do not have linkages or a early e-units that works on gravity.
You just have to use common sense on what you on the loco you are working with.
