India_Delhi Museum_PSMT (1): Patiala State Monorail Trailway. The only known locomotive-hauled monorail on the Ewing System ran from Patiala to Sunam (56km). Four locomotives of the 0-3-0 wheel arrangement were delivered by Orenstein and Koppel in 1907 and ran until the system closed in 1927. One locomotive and coach were rescued and restored to working order for Delhi Museum and are seen here from the “outrigger” side on 11 December 1979.
