This loco seems to be very reluctant to move.  I've tried several different settings for CV2 and it still takes up to speed step 6 or 7 for any significant movement to take place (28 speed steps) regardless of the setting in CV2.  The highest I've tried is 48. 

Would a different decoder make a difference or is there a CV setting that I'm missing.  Any advice would be appreciated.                   ...Tom

Where can I get a reference document for the dual function decoder that comes with this locomotive?  Thanks.                                                     ....Tom

I agree JohnTom and the decoder works just fine but it is a very basic decoder which only allows the user to specify the start voltage, CV 2, to determine the speed profile.  I'm looking for a more robust version of the decoder that also has a maximum speed and a medium speed, CV 6 and CV5.  And, decoders with this capability also come with speed tables which gives the user even more flexibility.             ...Tom

Is there a decoder available for this great little locomotive that provides a little more function than the one shipped with the loco?  I'd like to improve speed control via a Speed Table.  Thanks in advance.                                 ...Tom

I just became the proud owner of a Doodlebug but, much to my chagrin, one side of the rear truck is missing the plastic piece that covers the wheels.  Guess what, without that piece the wheels tend to fall out.  Does anyone know where I might get a cover or an entire truck for this thing.  I haven't called Bachmann yet.  Thanks.                                   ...Tom
