The longer of two tunnels on the old Newry to Armagh railway line. The line continued in operation until 1933 when, following a strike, the passenger service between Goraghwood and Armagh was withdrawn, and the Armagh - Markethill section closed completely. Goods traffic continued on the Markethill to Goraghwood section until 1957, and in 1965 the line closed completely. Some facts and numbers about Lissummon Tunnel: At 1759 yards (1608 metres) long - 1 yard short of a mile - it is the longest railway tunnel in Ireland. It is perfectly straight and runs approximately in a SE-NW direction. From one end you can see the light at the other. It is lined throughout with stone and brick and along the north wall are safety alcoves at 20 yard intervals. The track rises throughout the tunnel at a gradient of 1:75 (a climb of approximately 70 feet over the length of the tunnel).
