UP 7792 flies eastbound out of Maricopa with a hot intermodal. Assuming it meets braking reqs, the train is probably doing between 70 and 75 mph here. Apologies to duramax6600 for the title =).
A westbound manifest approaches the White and Parker crossing as some douche in a green Nissan decides that and additional 1 minute and 29 seconds spent waiting for a train is just too damn long.
