I recently had a very strange derailment in TS 2020, and I would like to know if anyone else has experienced a freakish derailment like this. I was running an 80 car or so intermodal train on Marias Pass starting at Whitefish. The train had four BNSF C44-9Ws up front and one at the rear serving as a DPU (Distributed Power Unit). The speed limit after clearing Whitefish is 70 MPH, but coming into Columbia Fall it drops to 45 MPH I believe. I had gotten the train up to 62 MPH when I reduced the throttle to idle gradually so as to avoid a run in of the slack and waited the ten seconds necessary before setting up dynamic braking. As you can see on my HUD, I had gotten the dynamics to N2 before suddenly everything derailed. The screenshot I took is toward the rear of the train, but it gives a good idea of what it looked like. The derailment happened right outside of Columbia Falls on Main 2 West. I've heard stories of real-life accidents where an engineer applied to much head end breaking force, causing the train to have so much buff force (force of car movement pushing on the head end of the train) that it derailed. Is that what happened here, or is this just a TS quirk? Any insight would be greatly appreciated, as I always try to run as accurately as possible to real North American practices. God bless.
