Reading the directions that came with the loco, I noticed it stated it was a 28 speed decoder.  Is this why it runs very hot while running with 128 speed steps?  Also is there a resource for the linkage to discuss repair between front trucks and read loco trucks.  They are not turning together.  Any suggestions? 

I'm having some trouble with pickup on my Tsunami 2-10-2 engine.  The rear truck does not pickup at all and as I understand it, the engine should make noise even if tender is not on track.  I'm not getting that.  Any suggestions concerning wiring issue, or might it be a decoder issue?  thanks
