I may have encountered a bug, but I wanted to confirm whether or not this behavior is correct. In the GP38 and similar freight trains in Sand Patch Grade, I tried to make a two-car unit have a dead-in-tow trail that the lead would pull. I tried to do this according to the following information on the wiki: Lead car- Engine Run: ON Generator Field: ON Control & Fuel Pump: ON Brake Cut-off Valve: FREIGHT MU-2A Valve: LEAD OR TRAIL Trail car- Engine Run: ON Generator Field: ON Control & Fuel Pump: ON Brake Cut-off Valve: CUT-OUT MU-2A Valve: LEAD OR TRAIL However, even though the three power switches in the trail car are all on, the trail car always seems to produce power when I control the lead car. The only way I've found to truly disable the engine control of the trail car is by turning the isolation switch. My understanding is that if the power switches in the trail car are on, then the trail car will ignore signals from the lead car and just remain idling. But that doesn't seem to ever happen, as power is always produced. Is this working as intended? Am I missing something here? Thanks! Edit: Also if anyone asks, I have radios disabled in both cars.
