The accident took place at an urban grade crossing intersecting Avenida Paseo de la Cruz and Avenida Ferrocarril in the central sector of Aguascalientes, Mexico.

Based on official reports from local municipal traffic authorities and emergency personnel in Aguascalientes, the 58-year-old truck driver was executing the illegal U-turn out of a mix of reckless driving impatience and a severe miscalculation of his turning radius.

Investigators and local media outlets noted the driver explicitly heard the approaching locomotive sounding its horn as it neared the intersection. Instead of stopping behind the marker to wait for the train to pass, the driver made a reckless, split-second decision to try to whip the truck around to beat the train and avoid a lengthy traffic delay at the crossing.

The driver swung wide from the far-right lane. However, he completely failed to take into account the length of his 53-foot dry-van cargo trailer against the available space. Once he initiated the sharp turn over the tracks, he suddenly realized his path forward was completely blocked by a gray Dodge RAM pickup truck parked legally a few meters past the rails. Because of that obstacle, he ran entirely out of forward maneuvering room, trapping his rear tires and chassis directly in the train's line of travel with absolutely no time left to escape.

It's yet another view of that monorail crane accident.

Context: This is a steam powered railway still in operation between the historical towns of Tiradentes and São João del Rei, Minas Gerais, Brazil. Only available at weekends and holidays, it is one of the coolest things for tourists and ends at a railway station with a railway's history museum. This railway operates uninterrupted since August 1881.
