Im looking to add a dcc with sound first generation Alco diesel to my engine fleet.  I see Bachmann has several to choose from.  Do the sounds include starting and stopping the engine?  And do they provide the realistic 'warble' Alco engines were infamous for?

I purchased the alco 2-6-0 and ran it for a few months.  Suddenly, I noticed I was missing a rivet on the reversing gear.  Is there a way to order replacement rivets for driving gear?  A few months back I ordered what I though were replacement cylinders and valve gear but I received a set for a different engine.  Not sure what to do at this point.

I just purchased a spectrum dcc 0-6-0.  I have a NCE control system.  I was able to enter the default address and get the engine operating.  I immediately noticed that the engine was slugish in response to the throttle.  I entered "programming on the main" and assigned the engine a new address.  I then entered the new address and the engine responded.  I then returned to the programming on main and changed the speed steps to 28.  There was no change.  I then tried 14 speed steps.  Again, no difference.  I'm not sure what else to do and would appreciate your wisdom.
