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.

[6] Maharaja Sir Bhupinder Singh of Patiala got this unique railway system constructed to facilitate movement of people and goods in his state.

Colonel Bowles has earlier successfully used monorail based on Ewing System (designed by William Thorold) during his stint as engineer during laying of tracks for Bengal Nagpur Railway for transportation of construction materials.

Maharaja Sir Bhupinder Singh made him chief Engineer for the PSMT project.

A 1908 edition of Imperial Gazetteer of India described the PSMT as "a mono-rail tramway, opened in February, 1907, [which] connects Basi with the railway at Sirhind".

[1] An ordnance map of 1913 also shows a tramway running along the west side of the road, but does not mention the PSMT by name.

Its model still holds good for introducing mass transit system in congested urban areas where laying of train or tram tracks is not possible due to space constraint.

Colonel Bowles described the route of Patiala-Sunam line as starting from goods yard of North Western Railway (NWR) at Patiala.

In his letter to H. R. Ambler, Col. Bowles wrote that the locomotives were heavy for 18 lb/yd rail (9 kg/m), thus they were not used on Sirhind – Morinda line.

Col. Bowles categorically stated that the steam locomotive did run between Patiala Station and City Mandi i.e. a distance of about a mile.

The track of PSMT was constructed by firm named Marsland and Price, who were based in Bombay.

If it were not for a Mr. Mike Satow, a historian of things railroady in India, who discovered the remains in 1962, it would have disappeared from memory by now and so this page is dedicated to him.

Largely due to him, one locomotive was restored to full working order by the Northern Railway Workshops at Amritsar.

They also reconstructed the Chief Engineer's private inspection car on an old underframe and the two were placed as an operating display at the National Railway Museum of India.

According to a memorandum dated 2 October 1908, found amongst Colonel Bowles papers, PSMT carried 20,000 passengers in a month on Sirhand – Morinda line.

There is no account available for fares or number of passenger or quantity of goods carried on Patiala – Sunam line.

related to PSMT was not preserved and thus what could have been valuable source of information on this unique monorail was lost forever.

[9] Mr. Donald W. Dicken's article carries a picture captioned "Motor Engine Trial On Patiala State Monorailway".

PSMT was forgotten even in Patiala, until its remains were discovered in a Public Work Department (PWD) shed by Mike Satow in 1962.

Thereafter John Day and Brian Wilson mentioned PSMT in detail in their book Unusual railways in 1957.

Based on these information, Day wrote another article that appeared in Railway World magazine in 1962.Satow took it upon himself to find the remains of PSMT and discovered the same in a PWD shed in Patiala in 1962.
