I see a lot of Youtube videos where a long semitrailer is high-centered on a crossing with a short, significant grade before the crossing.
There are three hot springs in the vicinity of Burning Man and the B:M closes them to public access during the event to prevent too many people damage. A handful of Earth Guardians are at each pool to enforce that and are changed out three times a day.
The Black Rock Rangers drive the van and two of them are about 20 miles north but the third is close to the city, just on the other side of the UP (ex-western Pacific) tracks. The trains barrel through at 60+ and the SOP is to pause at the crossing with the windows down, make everybody shut up, then cross the tracks.
