The Mount Gretna Narrow Gauge Railway was a narrow-gauge line of the Cornwall and Lebanon Railroad in the state of Pennsylvania that operated between 1889 and 1916. The Cornwall and Lebanon Railroad earlier had established a station and picnic ground at Mount Gretna. History The Gilded Age iron industrialist and railroad president Robert Habersham Coleman decided that a narrow-gauge railroad to the top of nearby Governor Dick Mountain would provide an additional tourist draw, and a spur at milepost 0.75 could service the Pennsylvania National Guard rifle ranges nearby. The line was built to the rare (in North America) and very narrow gauge of . Locomotives, apart from an early and unsuccessful H. K. Porter, Inc Forney locomotive, were three "American" types (#11, #12 and #15) built by Baldwin Locomotive Works. Locomotive #12 was ordered on 22 June 1889 and built in only 8 days to be ready for anticipated Independence Day crowds after the Porter Forney wheelbase proved too rigid for reliable service on small-radius curves. The Baldwin locomotives featured lagged smokeboxes and were the only gauge s ever operated in North America; although Baldwin built a gauge for the Ferrocarril de Tacubaya of Mexico City in 1897. Rails weighing were spiked onto the face of ties long. A turntable, engine-house, water tank, runaround track, and storage tracks were near the junction with the Cornwall & Lebanon at Mount Gretna. Return loops were built near the rifle range and around Governor Dick peak. During the summer of 1889 passengers were carried in one conventional coach and 7 open-sided observation cars boarded from long foot-boards running along the length of either side of the car. These eight passenger cars were built by the Jackson & Sharp Company. Two more observation cars were added when locomotive #15 was purchased for the summer of 1890. At first the railroad was popular, but the tourist trade declined after the novelty had died down. The loop around Governor Dick was dismantled after the summer of 1896, but the railroad continued operation for the National Guard rifle range. A serious accident in 1915 killed off that traffic. One of the observation cars overturned on a sharp curve when a large number of guardsmen attempted to board simultaneously from one side of the car. There were some serious injuries, and the tiny railroad ceased operation in the summer of 1916, shortly after its parent company's purchase
