context_page_description: The River Plym is a river in Devon, England. It runs from Dartmoor in the centre of the county southwest to meet the River Meavy, then south towards Plymouth Sound. The river is popular with canoeists, and the Plym Valley Railway runs alongside a section of the river.
context_section_description: HMS Plym, a River-class antisubmarine frigate, was named after the river during World War II. It carried out convoy escort duties in the North Atlantic and was later destroyed in the UK's first nuclear explosion.
  When it was in operation, the Cann Quarry Canal left the river at Marsh Mills.
  The Plym Valley Railway runs alongside the River Plym. It opened in 1856 as a section of the South Devon and Tavistock Railway, which followed the river as far as the tributary with the River Meavy. The line closed to passengers in 1962, and goods services stopped four years later. The new railway is volunteer-run railway which operates steam and diesel hauled train rides. The first section from Plym Valley from Marsh Mills station opened in 2001, with an extension to Lee Moor Crossing in 2008. In 2013, the line was extended to Plymbridge. The remainder of the line forms part of the Plym Valley Trail, a cycle route from Plymouth to Ilfracombe.
