Pmr 720

Steamtown Heritage Rail Centre, Peterborough

 

Pmr 720 and W 901 displayed in the roundhouse at Steamtown, Peterborough on 7 June 2007.

Pmr 720 is sans boiler clothing, which helps preserve the boiler barrel even if a rather unauthentic look.

Pmr 720 represents the final WAGR development of the Pacific locomotive – the fine Pm/Pmr class built by North British Locomotive Company, Glasgow in the post-war years. 35 Pm / Pmr class locomotives were built, the first 18 as Pm-class while the final 17 locos were further enhanced with roller-bearings on the driving wheels, hence Pmr class. Although designed for passenger service, the Pm/Pmr-class proved better suited to fast freight duties and lasted in that capacity until the end of WAGR steam. (For more information about the Pm/Pmr-class locomotives, refer to class leader Pm 701.)

Pmr 720 entered WAGR service on 29 June 1950 and was officially withdrawn on 14 August 1972, giving a working life of   22 years. Several modern WAGR steam locomotives remained in storage through the 1970’s which provided an opportunity for their preservation. Pmr 720 was among these lucky machines, finding a home at Steamtown Peterborough in 1979 where it was restored to operation in the 1980's and ran tourist trains to Oorroroo and Quorn.

Unfortunately, heritage railway operations at Steamtown Peterborough finished around 2000 but the site now hosts a very worthwhile railway museum based on the roundhouse and workshop buildings. Pmr 720 was displayed in one of the roundhouse stalls at the time of my visit in 2007 (per photographs on this page) in company with other steam locomotives in the collection W 901, W 907 and T 199.

Peterborough has an interesting railway history as an important railway junction, locomotive depot and workshop supporting the broad-gauge railway to Adelaide via Burra, plus narrow-gauge lines to Broken Hill, Crystal Brook and Oorroroo / Quorn. A complex arrangement of multi-gauge track and bogie change apparatus was required at various stages over the years, but ultimately the standard-gauge East-West route opened in 1971 became all that remains following closure of the broad gauge line south via Burra and the narrow gauge line north to Oorroroo and Quorn. On a trip to Adelaide on the Indian Pacific in May 1987 I recall watching grain being transhipped from narrow gauge to standard gauge wagons in the Peterborough yards as various employees milled around; the inefficiency of this arrangement an example of the break-of-gauge dilemma at various Australian locations. Oorroroo is the site of large grain silos but alas the line was not converted to standard gauge, instead being closed and lifted around 2009.

W 901 is in the adjacent stall.

Happy days for Pmr 720 ‘Keith Smith’ in steam at Peterborough; I believe this view dates from the 1980’s.

A more recent photo of Pmr 720 under repair in the workshop at Peterborough, which is part of the museum complex.

The clothing has been stripped from the boiler barrel.

You can feel the steam energy in this shot, with the safety valves lifting.

Pmr 720 is wearing lined black livery but in WAGR service the Pm/Pmr-class locos were painted Larch Green.

Alas the branch line to Oorroroo and Quorn was lifted in 2009 or thereabouts.

Pmr 720 heads a sombre queue of stored Pm/Pmr and W-class locos at Narrogin, dated 11 October 1970.

The siding is strewn with ash and coal fines, typical of a busy steam loco depot!
