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.

Built in 1923, the Flying Scotsman was the first steam locomotive to run at 100 miles an hour and to star in its own feature film. This is the untold story of the iconic Flying Scotsman-the very best in the engineering of its time.

In the first half of the 20th century, America's railroads were radically transformed by the innovation of gargantuan steam locomotives. Pushed by the need to haul ever longer and heavier trains, the nation's locomotive works responded with the invention of awe-inspiring articulated engines. Delivering up to 7,500 horsepower, these steel behemoths could haul mile-long, 15,000-ton trains. In this riveting program, journey back to the golden age of steam for an up-close look at these legendary locomotives. See the Union Pacific's famed "Big Boy" in action and ride the rails of the Chesapeake & Ohio and Norfolk & Western railways. Meet the men who drove engines like the Allegheny and Yellowstone, and visit the museums and yards where the largest steamers ever built remain preserved in time. THE HISTORY CHANNEL' proudly presents this rollicking retrospective, sure to set any rail fan's heart pounding

In August of 2002, former Santa Fe steam locomotive 3751 returned to the rails for a thrilling excursion from Los Angeles to Williams, Arizona and return in honor of the NRHS 2002 National Convention. Leaving Los Angeles, the mighty 4-8-4 battled the grades of Cajon Pass before setting out across the desert to Needles, thrilling spectators with her awesome displays of steam power. The following day, the 3751 completed the trip to Williams where she prepared to head up the Grand Canyon Limited excursion. This highlight of the Convention featured the 3751 running on the Grand Canyon Railway, doubleheading and tripleheading with GCRy's own steam power! The scenic splendor of South Rim vistas framing nostalgic images of doubleheaded and tripleheaded steam on the rails - it's an incredible sight that can't be beat!

For nearly 47 years, the Southern Pacific Railroad relied upon its massive AC-type steam locomotives to haul freight and passenger trains throughout California and neighboring states. Built to provide the power and flexibility demanded by the mountainous passes they traversed, these giants were constructed with their cab in front of the boiler, thus earning them the name Cab Forwards. The last Cab Forward revenue train ran in 1956, after which all but one were scrapped. From then on, film coverage of these AC-class engines was eagerly sought, hard to locate, and highly prized. Now, after years of research, Pentrex has assembled an awesome collection of footage and still images of SP AC-1s through AC-12s spanning the years 1927 to 1956.
