I have the  new K4. I had a problem with it running only in reverse using an MRC tech 4 360 (DC) or Tech 2 2500 (DC) Pack . Sent it to Bachmann for repair. Bachmann stated, "the K4 will not run on pulse DC packs, must use straight non pulse DC."  I triad a Bachmann power pack. It worked great. Have since prchased DCC system.
It runs much better.

Thanks James in FL.

Does anyone know if the Bachmann's non spectrum 2-6-0 mogul engine drive wheels are gauged to NMRA standards? The reason I ask: Do to some very good reviews of the 4-8-4 Northern.  I decided to purchasethe 4-8-4 Northerb (current run). The wheels were out of gauge and when I gauged the wheels they lost friction on the shafts and will not stay quartered. The engine is now slated for the junk box.
