Just bought N scale Bachmann no. 89552 and 89752 tenders DCC ready. What type of of mobile decoder options do I have? Would like to add sound if possible. Need help on this. Thanks
89552 is the short USRA. Sound in that tender is going to be dificult.
89752 is the standard USRA. Sound may be a little easier.
What loco are you going to use these with? To use the DCC readyness of the tenders, you need a loco with the 6 wire umbilical cord between the loco and tender, or create your own.
