The Leighton Buzzard Light Railway (LBLR) is a narrow gauge light railway in Leighton Buzzard in Bedfordshire, England. It operates on a 2 ft (610 mm) gauge, and is just under 3 miles (4.8 km) long. The line was built after the First World War to serve sand quarries north of the town. In the late 1960s the quarries switched to road transport and the railway was taken over by volunteers, who now run the line as a heritage railway.
A large collection of steam and internal combustion locomotives run on the line. Visitors can ride the train and are issued with an Edmonson ticket. There is a collection of industrial railway locomotives at Stonehenge Works at the northern end of the line.
