I assembled a mixed train of 50 cars to run on the Pokey, pulled by 2 sd402's, and a gp40.. Around milepost 405 crossing a bridge my air dumps. I reset but the air goes up to between 40 and 60 psi then dumps again. Uncoupling the locos allowed the air to reset, then I tried to recouple but the gp40 would not couple to the lead car. I use Bin. All the rolling stock came in the megapack.
My sd files were fine. I even raised all the bounding box minimums with RoutRriter. I didn't even make it to the bridge when my air dumped. So I went into the setup in the sim. If I find the idiot who turned the alerter on I will kick my self in the behind. Thanks Kurt for your help. The older I get the worser I get.
I completed my run on the Pokey with no problems. I had replaced all the KLW cars in my consist with 42 KLW coal cars ( one car 42 times). I will rebuild the consist as the original mixed freight and run it again, but I expect no problems since bin cntrl 9 showed all the bounding boxes ok when the problem started. At least to me they looked ok.
