Waited for train to pass and gate to raise at railroad crossing, then started to cross tracks. The car went halfway across the tracks, then the forward collision warning and automatic emergency braking activated, stopping us on the tracks. Tried again to move forward, but the collision alert and auto braking immediately activated for a second time, bringing us to a stop again. Finally was able to very slowly make my way through the crossing. I was on the tracks for 30-60 seconds. No train was approaching and it was only my wife and me in the car, but if I'd had six passengers with me and another train had approached, I am not sure I would have been able to get everyone out of the car in time. Note that there were no obstacles in front of the vehicle, but the sun was at a low angle from the front of the car and the sunlight was dappled through the treetops on the other side of the crossing (there's a left-hand curve after the crossing), creating a "moving" glare through the windshield.
