Bachmann OO NRM C1 Atlantic DCC Sound

Bachmann OO NRM edition C1 Atlantic 4-4-2 mini-guide, with photographs of the tender installation where a Zimo MX644D 21pin decoder is situated, with YouChoos Brick8 speaker and 330uF stay-alive capacitor. The loco has a Zimo MX685 function decoder to control a Seuthe #22 smoke generator, boiler door lamp and firebox glow light.

Sounds come in the form of YouChoos' Robinson O4 project.

The tender is neat - no modifications - just fit the MX644d, Brick8 and stay-alive.

A brass replacement chimney is fixed in with DevCon 5 minute epoxy. A chunk off the front of the boiler's metal weight is removed in order to accommodate the Seuthe unit and a slice off the weight's top provides room for the MX685 function decoder, resistors and wires.
