I know that PS 3 can operate with both a DCS control system or DCC (Digital Command Control). I also know that if you have a 2 rail capable MTH loco there is a DCC/DCS switch to select which control system to use
Is there a DCC/DCS switch on PS 3 locomotives that are equipped for 3 rail operation only?
If not, can such a switch be added?
Is it via a socket on the PS 3 board, or does one have to make solder connections to the board itself?
Thanks in advance
