Like the Pennsylvania Railroad, the B&O was caught off guard in the early 1930's missing a historically significant piece of history. The original "Lafayette" steam engine was built in 1837 by Norris Locomotive Works in Philadelphia had long been scrapped (you'd think they'd have learned by the 1950's and 60's). This replica was built in 1927 to be featured in the "Fair of the Iron Horse" during 1933/ 34. What made this engine significant was that it was the first engine with a horizontal boiler which likely set the standard configuration for steam engines from that point forward. It also had another first; a pilot truck that swiveled to help steer the engine. This replica was made operational once again by the Strasburg Rail Road shops for an event at the B&O Museum in 2002 for yet another "Fair of the Iron Horse" which failed to materialize after a heavy snowfall cause the roof to collapse at the Museum, since repaired.
