The Union Pacific Railroad produced its classic documentary film Last of the Giants in 1959 as a fitting tribute to the world's largest steam locomotives-the Big Boys. UP cameramen filmed the Big Boys over a three-year period, which Pentrex re-released in 1992. It ran for a total of just 23 minutes, leaving hours of unused footage that was set aside for many years.
