3801 - Restoration

Restoration

In November 1980 David Hill Chief Executive of the NSW State Rail Authority (now RailCorp) enquired about the suitability of restoring 3801. Hill had the 1988 Bicentenary of British settlement in Australia in mind, and saw a restored 3801 as a representative of Australia's railways. The boiler was the major item needing repair and an investigation needed to be carried out to ascertain if restoration was viable. A visit was made to the South Maitland Railways (who at the time still used steam engines) to learn about modern boiler techniques. It was discovered that many advances had been made and it was possible to return boilers to service which previously would have been scrapped. The next step was to examine the boilers of the other preserved 38 class members - 3820 and 3830 (though 3813 had survived, it was completely stripped and in two different locations) - and compare them with 3801's boiler. It was decided to use the boiler already in 3801, however the inner firebox had suffered thermal fractures and would need extensive repairs. Restoration was deemed possible and a fund-raising appeal began.

With some finance raised, 3801 was taken to Newcastle for restoration by the Hunter Valley Training Company - an apprenticeship scheme later involved in the restoration of 3830. This was due to the railway's workshops being stretched by regular work.

The firebox was to be completely replaced, however the dies and jigs used to press the boiler metal had been scrapped, so the old firebox was used as a template. The new firebox had a different shape and this reduced the boiler pressure to 215 psi. It was decided to weld the new firebox and some conservative engineers were sceptical as to whether this would work. Repairs and reconditioning of many other components were also carried out. The tender tank was so rusted, it needed to be replaced. The new tank was welded rather than riveted and this resulted in a sleek, plain tender. On 8 November 1986 a fire was lit for the first time. By 10 November, 3801 was running around nearby sidings. More short trials followed and on 15 November, 3801 was handed over and hauled a train to Maitland. More trial runs followed and on 19 November 1986, 3801 headed from Newcastle to a grand ball on the concourse of Sydney's Central Station.

Famous quotes containing the word restoration:

    I claim that in losing the spinning wheel we lost our left lung. We are, therefore, suffering from galloping consumption. The restoration of the wheel arrests the progress of the fell disease.
    Mohandas K. Gandhi (1869–1948)

    In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.
    Irving Kristol (b. 1920)

    Men who are occupied in the restoration of health to other men, by the joint exertion of skill and humanity, are above all the great of the earth. They even partake of divinity, since to preserve and renew is almost as noble as to create.
    Voltaire [François Marie Arouet] (1694–1778)
