The Parc Linéaire Le P'tit Train du Nord is a multiuse recreational rail trail located in Quebec, Canada. It runs through the Rivière du Nord valley. It originally was a railway line operated by Canadian Pacific Railway which operated it at a continuous financial loss since its construction in the 1890s. During the 1990s, it was dismantled to make way for a recreational multi-use trail except for the portion between Montréal and Saint-Jérôme which is still in service as the Saint-Jérôme line. Prior to decommissioning, passenger traffic on this line was so scarce that it gave way to the humorous and intricately philosophical and poetic song by Felix Leclerc, "Le train du nord".
