The Mount Tom Railroad, also known as the Mount Tom Railway, was a funicular mountain railway on the northeast slope of Mount Tom in Holyoke, Massachusetts which was operated by the Holyoke Street Railway from 1897 until 1938. Built in 1897, the railway quickly gained national fame when it was visited by President William McKinley who remarked upon the beauty of the mountainside. It was closely identified with the Summit Houses which adorned the mountaintop with the most ornate first two designed by local architect James A. Clough. At the foot of the railway sat Mountain Park, which connected the cable railway with the Holyoke Street Railway system.
