PSMT meaning in Regional ?

Patiala State Monorail Trainways (PSMT) was a unique rail-guided, partially road-borne railway system running in Patiala (British India) from 1907 to 1927. PSMT was the second monorail system in India, after the Kundala Valley Railway, near Munnar in Kerala, and the only operational locomotive-hauled railway system built using the Ewing System in the world. The Kundala Valley Railway pre-dated this, also using the Ewing system between 1902 and 1908, although this only used bullocks for haulage. Following the conversion of the Kundala Valley Railway from a monorail to a narrow gauge railway in 1908, PSMT was the only monorail system in India until its closure in 1927. These were the only instances of a monorail train system in India, until the Mumbai Monorail was opened on 2 February 2014.

A locomotive and a coach of PSMT have been restored, are in running condition and are exhibited in the Indian National Rail Museum, New Delhi.
