I don't live there anymore so I don't have a horse in the race. I just know for a fact the BNSF doesn't care about 42nd with the exception of the crews that try to avoid blocking when they can. When I lived in GF I would always try to avoid 42nd st. when possible. I do the same thing in Fargo-Moorhead. Always try to avoid railroad crossings that I know I could be stuck at for a while. I am an impatient person though.
The BNSF doesn't have a schedule that can be coordinated. They also don't give a s&*^ about blocking that 42nd crossing. The train crews are aware of it and try to avoid blocking it, but a lot of times they don't have the option.
