This 50’ airslide hopper is mineral brown with white lettering and run on 100-ton Barber Roller Bearing trucks. Built as part of series 808000-808099, these hoppers were removed from revenue service and re-stenciled for use as a buffer car in the late 1990s. Often seen separating locomotives from loaded ethanol or crude oil tank car unit trains, HAZMAT buffer cars are commonplace across the BNSF network.
