 As older forms of transportation such as the canal boat disappeared , new forms arose . One of these , the electric trolley , began operation in Lock Haven in 1894 . The Lock Haven Electric Railway , managed by the Lock Haven Traction Company and after 1900 by the Susquehanna Traction Company , ran passenger trolleys between Lock Haven and Mill Hall , about 3 miles ( 5 km ) to the west . The trolley line extended from the Philadelphia and Erie Railroad station in Lock Haven to a station of the Central Railroad of Pennsylvania , which served Mill Hall . The route went through Lock Haven 's downtown , close to the Normal School , across town to the trolley car barn on the southwest edge of the city , through Flemington , over the Bald Eagle Canal and Bald Eagle Creek , and on to Mill Hall via what was then known as the Lock Haven , <unk> , and Nittany Valley Turnpike . Plans to extend the line from Mill Hall to <unk> , 3 miles ( 5 km ) miles south of Mill Hall , and to Avis 10 miles ( 16 km ) northeast of Lock Haven , were never carried out , and the line remained unconnected to other trolley lines . The system , always financially marginal , declined after World War I. <unk> business to automobiles and buses , it ceased operations around 1930 .
