Bachmann Doodlebug DCC with constant lighting

This is how we put a Digitrax DH126D DCC decoder and some constant lights using a bridge rectifier in to the Bachmann Doodlebug. This project was super fun! The constant lights in the passenger compartment look amazing. The Doodlebug also has a very interesting rear coupler arrangement that we have to think about using in projects like the Athearn DD40.
