The history or the only published information about PSMT line, is in the 1908 edition of the Imperial Gazetteer of India, which briefly states "a monorail tramaway opened in Feb. 1907 connects Basi with the railway at Sirhind. Col. Bowles who designed this system became the state engineer and laid the Patiala State Monorail Trainways (about 50 miles in length from Sirhind to Alampura and Patiala to Bhavanigarh). The track was a single rail along one side of the road. On this ran the load carrying wheels of the train while a large single wheel at the end of an outrigger ran on the road to keep the train upright.
