The Pennsylvania Railroad (PRR) T1 Steam Locomotive Trust is a non-profit organization that believes in thinking differently about preservation. Through hard work, dedicated volunteers and the financial support of many generous donors from around the globe, the T1 Trust is constructing PRR T1 5550. Slated to become the fifty-third locomotive of its class when complete, 5550 combines stunning art deco design with a unique 4-4-4-4 wheel arrangement. The PRR T1 represents the pinnacle of steam locomotive design in the United States. These locomotives had the capability of achieving speeds in excess of 120 mph, and anecdotal reports indicate that speeds of up to 140 mph were attained. In all, 52 class T1 locomotives were produced, 25 at the PRR's Altoona shops and 27 at the Baldwin Locomotive Works in Philadelphia. Sadly, not a single example of this magnificent machine escaped the scrapper's torch. We aim to right that wrong. We value preservation, education and history. The United States has a long and integral history with railroads and specifically, steam locomotives. The production of PRR T1 5550 will fill a large gap in that essential history.
