I have run the route on the EMD F40 loco on Boston Sprinter but after changing ends as the same way as peninsular corridor I find it is not possible to release the brakes. I cannot touch the MUA valve as it has no hyper spot and as soon as I set the controller to cut-in but it will not fully release the brakes. There is no manual for this but I have don the intro as this is not possible to skip, the EMD is on trail 6-26, cut-out and handle off but the cylinder gauge is not at 0 when the DSO is released. Straight air is also off. Is this trailer supposed to be useable or do I just have to reverse all the way from the EMD F40 cab?
Works fine for me. Before leaving the F40, 3 engine switches off, train brake handle to off position and independent brake to release. Let the BP fall to 0 before cutting out and setting the MU to trail. If you go the opposite way it takes quite a while for the BP to dump in the CTC car, just make sure it is fully zero before cutting out.
That's odd, the only way I could get the brakes to work when swapping to the cab car is by leaving the MU-2A valve on the F40 in Lead/Dead
