Aegis21 posted:2) how do I go about upgrading to TMCC ?
Why does it have the run/program switch and an RS/SS switch?
You'll need the R2LC-C08 board to enable the TMCC capability, it replaces the reverse board in the right hand socket. The RUN/PGM switch is the reverse lockout for conventional operation, when you upgrade it, it'll be indeed the RUN/PGM switch. The RS/SS switch won't do anything right now as you have a Signal Sounds board. If you replace that board with the RailSounds board and add the generic RailSounds Power Supply, you'll have full sounds. Then the RS/SS switch will switch the sounds on/off, the horn and bell are always enabled.
Yes, and you'll have to hook up that antenna wire to the antenna it apparently broke off from.
