an average of 300 tons of ore a day. Additionally, the mine's operators came to use Cobourg as their summer cottage areas, greatly increasing the prosperity of the town. The mine's productive period lasted only a short time; the last shipment on the line was in 1878, and mine shut down in 1879. By this point the Marmora area was well served by numerous lines, including the Central Ontario Railway which ran directly to the Grand Trunk lines at Trenton. Cobourg, Blairton & Marmora Railway and Mining Company The residual capital of the original CP&M&M was sold off to the Cobourg, Blairton & Marmora Railway and Mining Company, formed on 23 June 1887. Their interest was primarily in an attempt to connect the Blairton section to the Ontario and Quebec Railway which passed between the two ends of this branch. This was ultimately unsuccessful, and by this time several other lines, notably the Central Ontario Railway which ran directly through the Marmora mines, were providing service in this area. Under the GTR The line was finally sold off to the Grand Trunk on 1 April 1893. The Blairton section was immediately abandoned while the section to Rice Lake continued to be used for passenger service until 1898 when the line was officially closed. Rails were lifted after this period, and apparently shipped to France during World War I. The section between the GTR mainlines and the port in Cobourg were lifted in the 1980s. The route today Due to is early closure and lifting, the C&PRy was closed long before the conversion to rail trails become common. Most of the route has since disappeared. The sections north of Rice Lake are more visible, lately due to these areas remaining in agricultural use, and seeing less residential development. All that remains of the Blairton section are the docks on the Crowe Lake and the Trent. A small section through the Ashburnham section of Peterborough is now used as the Rotary Club Greenway Trail. Even the bridge is now mostly lost, although this was due largely to the raising of water levels that occurred after the Trent Waterway was finally completed in 1923, and the water levels were lifted to provide more flow into the locks. One portion of the bridge remains visible, stretching from the south shore of Rice Lake at Harwood. It appears as a land causeway, with trees and
