An abandoned incline railway on Dunderberg Mountain in New York. It was built between 1890 and 1891 by Henry J. Mumford and his brother, who operated a similar scenic railway in Mauch Chunk, Pennsylvania. The train would have gone up two inclines to the top of the mountain, where it would then coast to the bottom via gravity along a series of switchbacks.
Today, all that remains are some graded sections of roadbed and a stone tunnel near the foot of the mountain. It is a popular hiking destination, offering scenic views of the Hudson River.
