The Cobourg and Peterborough Railway (C&PRy) was one of the first railway lines to be built in Central Ontario, Canada. The line was initially considered in 1831 as a way to bring the products from the burgeoning area around Peterborough to markets on Lake Ontario through the port in the town of Cobourg. Before the railway the only means of travel was by stage coach lines between larger populated areas overland or by boat. A series of problems, including the Upper Canada Rebellion and the Panic of 1837, meant that construction did not begin until 1853, reaching Peterborough in 1854. The line ran directly over Rice Lake on what was then the largest trestle bridge in the world. However, it was not the strongest, and the bridge was shifted due to ice only a few days after opening. Problems with ice continued to be a serious concern throughout the railway's history. A series of companies took over operations of the C&PRy, including a lease to the shareholders of the Port Hope, Lindsay & Beaverton Railway, who ran a competing line only a few miles away. The new operators surreptitiously sabotaged the bridge, causing it to collapse in 1861. The southern portion of the line, below Rice Lake, had a second life from 1867 as part of the Cobourg, Peterborough & Marmora Railway & Mining Company. This was a network using the original C&P, a short run known as the Blairton Extension, and the Trent River between the two which was used to ship iron ore from the mines at Marmora to market. The line was successful for some time, until other lines pushed into the Marmora area, while the mines were running out of profitable ore. In 1886, the line was sold again to the Cobourg, Blairton and Marmora Railway & Mining Company, who operated it sporadically before selling it to the Grand Trunk Railway in 1893, who closed it in 1898. The rails were apparently shipped to France during World War I. Given its early disappearance, unlike many historical railways the C&PRy route was not converted to rail trail use. Most evidence of the line has since disappeared, although remains of the trestle are still visible, and rise from the lake during periods of low water.
