Almost all the steam and diesel power in my Run Room is MTH. The performance of the MTH engines with Proto-Scale 3-2T 3-Rail/2-Rail Conversion capibilities is unacceptable and I won't be buying those engines.
After running my "new" #20-3383-1 (engineering edition) I discovered it will not creap through my Ross switches (Ross 220 #8 switch and Ross 101 11 degree switch). I must run it through fast like I used to run my postwar engines (so I could blow the whistle).
Thorough investigation showed that the wipers on the engine rear axle are very fragile, and all wheels are insulated from the engine and tender housings causing a problem with conductivity with the outside rails. The engine has only 3 wheels wired to act as common to the outside rails and one of those wheels has a rubber tire.
After extensive improvements to my 20-3383-1 2-3-1 Pacific Steam Engine, the engine is on probation. See solutions here MTH 20-3383-1 2-3-1 Pacific Steam Engine or http://www.slsprr.net/features...0Pacific%20Steam.htm
