Locomotive 3642 is two-cylinder, simple, non-condensing, coal-fired superheated, 4-6-0 36 Class express passenger steam locomotive for the New South Wales Government Railways built in 1926 by Clyde Engineering.

In service[edit]

3642 was fitted with electric lighting in 1927 and was then fitted with 'Rosebud' Grates in 1932. In 1933 the locomotive received maintenance including an overhauled boiler from 3602, along with a new firebox, pistons and valve rods. The next year, its axle boxes were converted to grease lubrication. In 1936, its boiler was fitted with a new firebox and the engine was fitted with 'Cardew' water release valves. 1939, 3642 was fitted with the boiler of 3667 with a new firebox and was then fitted with the boiler of 3673 later that year. In 1943, with changes to draughting - blast pipe alterations and ashpan air openings were made. Between 1944 - 1958 further boiler replacements and repairs were carried out. 42 was out of service in 1961 due to cylinder problems. Following repairs it again failed requiring further repairs which were finished by December 1961 at Chullora. This included fitting of cast steel cylinders and 12" Trick-ported valves. In 1968 the engine was fitted with a power reverser, trailing sanding gear and tender kit lockers.

Demise and Preservation[edit]

Final withdrawal took place in 1969, at which point the loco was allocated to the NSW Rail Transport Museum and became part of their collection in 1970.

After restoration 3642 was part of the opening of the Port Augusta to Whyalla line with 3801 in 1972. In 1973, the engine was found to have cracking in its firebox and was taken out of traffic pending re-boilering. Spare boilers were inspected and found in good condition, the cost of the boiler refurbishment was estimated at over $20,000.

In 1979, 3642 was transferred to Goulburn Roundhouse in Goulburn, New South Wales. The engine was maintained by the NSW Rail Transport Museum under contract. In 1989 3642 was transferred back to Thirlmere. It joined LNER 4472 Flying Scotsman during the British engine's last day in Australia before its return to England.

In 1992, 3642 visited Melbourne, Victoria with fellow museum locomotive 5910. The two engines made a visit to Albury railway station, New South Wales to celebrate 30 years of standard gauge to Melbourne. 3642 made a trip to Melbourne for The Phantom of the Opera which included a parallel run with Victorian locomotive R 766.

In the December 1994 issue of Railway Digest magazine, a photograph of 3642 was accompanied by a caption stating that the locomotive had been withdrawn from service following the failure of an ultrasonic test on the rear driving axle and that there were no plans to repair the loco at that stage.[1]

In 1996 it was announced that 3642 failed its boiler inspection and subsequently became a static exhibit at Thirlmere.[2] In 2006 an announcement was made that 3642 would be restored and in 2008 it returned to service running a tour around the Sydney suburbs. At the end of 2008, a project to repaint the engine began. The project was completed in 2010.

2008 saw 3642 return to The Hunter Valley Steamfest after a 16 year absence. 3642, along with 3001, 5910 and 5917, were the founding locos of this event back in 1986.

In late July 2011, 3642 was taken out of service for a re-tyre of the all driving wheels and a small mechanical overhaul. This was completed and 3642 was returned to operational condition in April 2012.
