Does anyone know where is the MU Valve in that locomotive? because I would like to control that locomotive from another locomotive
There is no valve, the brake cut in/out and the MU setup is all controlled from the IFD screen on the control desk.
Does that mean I only have to enter a certain number on the "Feed Valve Set" on this monitor so that I can control this locomotive from another locomotive?
IIRC, all you have to do is hit i think F1, which brings up the setup screen, then you change the brakes to cut out and the MU setting to Trail, then save then exit. (I unfortunately can't provide pictures atm)
