ISO Experiences with the Weaver PRR C-1 0-8-0 locomotive?

I had one. Great details, didn't care for the smoke system Weaver uses. Pulled good had about 20 cars it pulled without a hitch. The only reason I sold it was because of my 4 track storage yard with 036 switches to save space and only switcher would be going there, it would derail going backwards from one track to another while sorting cars for a consist. Ended up using switcher in a forward only entering and switching cars between the tracks. Bought a MTH 0-8-0 that never gave me problems. Again, this was my observation on my trackage and the only problem I had with the engine, otherwise it was perfect in running, pulling, and detail and could creep great.
