I know the DCC decoders are rated by current capacity but what determines which decoder you put in your steam loco? I am going to get an NCE at the NMRA con tomorrow but I am not sure what decoder to buy?
Go to the Soundtrax web site. They have a list of all of their available DCC decoders (Sound) that suits Steam or Diesel by size and manufactures if that is what you want.
Top Hobby is another good site as to Tony's trains.
