I do the same thing. All four channels on the TIU are set to fixed and the TIU is powered through the auxiliary port. Power to the four channels comes from two Z4000’s. Almost everything I run is DCS or Legacy/TMCC but when I want to run a conventional locomotive I only need to close a throttle, put the conventional locomotive on the track, and we are off and running. Nothing extra required.
@Lehigh74 posted:That will work. On a TIU fixed channel or a variable channel that is set to fixed, you can use the transformer throttle for conventional locomotives. You can do it even if you don’t power the TIU with the aux port, but not on a track fed by the fixed one channel.
