                  Railroads 
                    require constant upkeep, repair and maintenance, so older 
                    railcars that are still roadworthy are often converted to 
                    Maintenance of Way duties, including maintenance of the right-of-way, 
                    tool and equipment supply and storage, and materials for railcar 
                    repair and wreck recovery. Founded in 1859, Santa Fe was one 
                    of the largest railroads in North America up until 1996, when 
                    it merged with Burlington Northern to form BNSF
                  .
