The East Broad Top Railroad National Historic Landmark in Orbisonia, Pennsylvania, (hereafter referred to as the EBT) is the oldest surviving narrow-gauge railroad east of the Rocky Mountains. It has been described as an “incomparable national treasure, comprising a site, a set of historic buildings and facilities, a community and a spirit that are – taken together – unique in this country. . . Nowhere in North America does such a complete and original industrial historic site exist.” The EBT was designated as a national historic landmark in 1964 and is nationally significant in the fields of commerce and transportation. The EBT is the best remaining example in the nation of a regional narrow-gauge railroad system. The EBT system probably offers the only opportunity in the nation to tell a comprehensive railroad industry story. The railroad is also a nationally significant, historic industrial workplace where relics from the technological age of steam can still be seen, heard, and smelled.
