The "Standard Railroad of the World"- such was the modest self-evaluation of the Pennsylvania Railroad. It grew to be the largest American railroad through sound, practical engineering and operating practices. But they were also willing to try any new innovation to enhance their efficiency. The variety of motive power that this philosophy created has long endeared the Pennsy to rail enthusiasts everywhere. Here is a sampling of what this great railroad has to offer. Steam, electric and diesel. Fast passenger trains, commuters, drag freights and heavy mineral trains. They're all included! The legendary K4 Pacific, in standard version, with poppet valves and with streamlined shrouding. The famed I1 decapods, that fans dubbed "Hippos", work on the point or as "snappers" around Horseshoe Curve, and four at a time on heavy ore trains on the Shamokin Branch. The Pennsy's fleet of duplex locomotives, the T1, Q1 and S1 are not forgotten. The enduring and graceful GG-1 electrics race past on the Pennsy's electrified speedway. First generation diesels, including the Baldwin "Shark" and "Centipede". Early intermodal, the Truk-Trains, are hauled behind shiny-new GP9's. The "Packsaddle", the Buffalo Line and the Horseshoe curve are all visited. Oh yes, the "More" is the coal hauling Bessemer and Lake Erie, with steam and diesel power!
