One of the advantages of DCS is the ability to uncouple cars away from uncoupling tracks. I am just getting started with DCS. I just plugged in a TIU to my layout and have had hardly any problems even though I didn't change or isolate feeders. I run my two PS2 engines with dummies, so the uncoupling idea doesn't work. Is there a way to get remote uncoupling other than putting the dummies in front?

You could run the coupler wires to a switch on the A, and run a 2 pin harness to the dummy. When switched in one direction the A fires, when the switch is in the other position the dummy fires. Many A units that are meant to be run with Dummies have this set up and use the 4 pin so that a light can also be controlled. G
Great idea. Would a PS1 coupler work? Another thread has me looking at parts on an early SD9 that I have. The switch is there, too. Thanks.

John,
Would a PS1 coupler work?
No, the required voltages are different.
PS-2 coupler needed, but PS-2 works on PS-1. G
PS/1 couplers have a much higher resistance and are designed to fire at 12V or more. PS/2 couplers will fire at 6 volts. I've used PS/1 couplers with TMCC conversions, as they seem to be compatible in voltage to the Lionel ones.
