A rear power unit besides pushing and lowering pull forces on the train, is able to assist with brake actuation by filling brake pipe. Is this possible to setup with a rear unit? I'm working with the AC4400 on SPG, and have a single unit at the rear. It's all setup correctly to push over radio and does that, but the pressures still take some time to get to the back, since the auto brake is cut-out. AFAIK being radio controlled, the rear unit should be able to assist with it's own compressor and reservoir, but not sure how to set that up. Also, can someone clarify the Distributed Power switch, on the AC4400 but no on other locos?
That would be the case in real life, but AFAIK Simugraph doesn’t model bidirectional brake pipe supply. In any event, the brakes are still always cut out (game and RL both) in all but the lead cab, since that only deactivates the control stand, not the compressors (which are automatic)
Ah ok. Two related but independent mechanisms. Too bad it's not modeled, as that's one of the major benefits. Also, I noticed that with a car EOTD, it sends the rear pipe pressure correctly, but when you have a loco on the end, you don't get that information. In one case the rear pressure indication seemed to have been of the trailing locomotive right behind the lead, which seems incorrect. Either I haven't figured out the details, or there are some issues and inconsistencies. It's useful to know the state of pressure at the back, so I estimate roughly by looking at the air flow, it's it's high it's still releasing, and when moderate flow, filling up.
