Some great info. on this thread!
So, it finally happened. Never had any operating issues on the older layout with this 44 tonner using G.G. Switches but the unit failed to operate on the new layout. When the engine encounters back-to-back or a group of G.G. switches, it shuts off. Another problem is it hesitates around Atlas O O36 curve tracks.
So, all you need to do is swap roller assemblies with a subway car to fix the issue. If you have MTH passenger cars, you can do the same. These older style rollers were the best. Make sure you keep the same screw with each unit as they are different in length. 44 TONNER USES THE SHORTER SCREW as equipped.
MTH sure got away with a lot of goof ups over the years that us operators had to eat. Should have been a class action with those QSI PS1 engines too.
We shouldn’t have had to do this especially at the ridiculous price that it was.
( Roller swap )
Easy fix!
