Thank you Jim.perhaps I disd not express myself clearly I am aware of the functions of the decoder .on the sht that came with the unit they had a line drawwing of where the decoder plugs in and I thought perhaps bachmann had a specific decoder for this purpose.i will certainly look at the digtrax decoders you referred to.I may use an NCE N12 RS WHICH WOULD FIT IN THE SPACE ALLOCATED AND I COULD HARDWIRE IT IN.regards Bill SCHWENSEN

can anybody please advise me of the correct dcc decoder  (part no or brand) to use in my newly aquired MOW ballast spreader thank you
