The Vapeur du Trieux steam train runs from the seaside town of Paimpol along the Trieux river to Pontrieux. The locomotive, a Mallet, was built in 1911; its restoration was completed in 2005. It now pulls six carriages: some first class, with upholstered seats, from the 1950s and two rather more basic second-class ones from the 1920s.
The train meanders at just under 20mph past river scenery, including the Chateau de la Roche Jagu and the house at the centre of the Seznec Affair (subject of a forthcoming post).
The journey terminates at Pontrieux, a small but attractive town famous for its lavoirs - private washing facilities on the riverside.
