Daily work is conducted in a safety sensitive environment where the working conditions can include diverse and extreme weather conditions (hot, cold, rain, snow, and sleet), walking and performing work on uneven surfaces, working around loud noises, fumes, and heavy/moving machinery. Hostler Truck Operators operate heavy trucks (up to 65,000 lbs) with trailing units in the yard, maneuvering tight spaces, using on-board computers to communicate with management, and handling railcar spotting and chassis management.
