Starting from Strone near Port Glasgow at Lady Octavia Public Park heading south east follow the Sustrans route 75 on the disused Paisley and Renfrew railway line and ending at Linwood where the Sustrans route meets route 7. The line was opened in 1837 with steam locomotion from the start. It was expensive to run and profits disappointing so horse traction was substituted to save on the operating costs. It was sold in 1847 to the Glasgow, Paisley, Kilmarnock and Ayr Railway. The horse traction continued until 1866. It closed to passengers in 1967, and to goods traffic in 1981. The route is just over 12 miles long and passes by Mid Auchinleck, Kilmacolm, Bridge of Weir, and ends at Linwood. At Mid Auchinleck the route fades a bit with poor signage so do study a map before negotiating it. Also at Kilmalcolm it fades again but looks quite simple to decipher, keeping in a relatively straight line brings you to the ex-railway station which is now a public house! **There is opportunity to travel further on Sustrans route 7 going south west to Glengarnock.
