The O'Shannassy Reservoir supplies water to the Silvan Reservoir, which distributes it to most parts of Melbourne. The dam was completed in 1928 and is an earthfill embankment with a reinforced concrete core wall.This photograph is significant as it provides a detailed insight into the Boards activity and construction of one of Melbourne's most important water supply systems. Furthermore, it is of historical importance to the history of Melbourne while it is representative of shaping Melbourne's environments, transforming and managing land and natural resources, and providing urban infrastructure and services. This photograph also covers the theme of Safety, depicting the safety standards of the time particularly with clothing.

Double Headed Rail from Ravenswood Station Siding which was dismantled circa 1987 the two rails were stored for a time at Maldon before being donated to Puffing Billy Museum Bearing makers marks of Wilson & Cammell - Dronfield- Steel works Wilson & Cammell made Steel rails at their Dronfield Steel Works, in Dronfield, North East Derbyshire, England from 1872 - 1883 Double-headed rail In late 1830s Britain, railway lines had a vast range of different patterns. One of the earliest lines to use double-headed rail was the London and Birmingham Railway, which had offered a prize for the best design. This rail was supported by chairs and the head and foot of the rail had the same profile. The supposed advantage was that, when the head became worn, the rail could be turned over and re-used. In practice, this form of recycling was not very successful as the chair caused dents in the lower surface, and double-headed rail evolved into bullhead rail in which the head was more substantial than the foot. Info from Wikipedia - Rail Profile https://en.wikipedia.org/wiki/Rail_profile The first records of double headed rail being used In Victoria by Victorian Railways was in 1859, the rails, chairs, oak and trenails were imported from UK. After the 1870’s the Victorian Railways went over to using flat bottom rails, but they still needed replacement double headed rail for lines already laid and this continued up to at least 1883 Wilson & Cammell - Dronfield- Steel works Wilson & Cammell made Steel rails at their Dronfield Steel Works, in Dronfield England from 1872 - 1883 Mount Alexander & Murray River Railway The Melbourne, Mount Alexander & Murray River Railway Company received parliamentary assent in February 1853 to build Victoria's first inland railway from Melbourne to Williamstown, and Melbourne to Bendigo and Echuca. Construction commenced in January 1854 with work on a pier at Williamstown but lack of funds slowed progress, eventually prompting the company to sell out to the government. The 100-mile (162 km) section to Bendigo opened in October 1862. Its cost of £35,000 per mile made it the most expensive railway ever built in Australia. In 1864, the line was extended to Echuca, tapping into the booming Murray-Darling paddlesteamer trade. info from Museums Victoria - Victorian Railways https://museumsvictoria.com.au/railways/theme.aspx?lvl=3&IRN=450&gall=456 1863 Ravenswood Station open on the 1st Feb 1863 Victorian Railways - purchased and imported the Rail and Chairs from Raleigh, Dalgleish, White and Co.

The Ravenswood Railway siding was constructed in 1862 with 12 feet wrought iron double-head rail held in cast iron chairs with Ransom and May patent compressed keys. Trenails held the chairs to the sleepers and the joints were secured in joint chairs. Joints were subsequently joined using fish plates. It formed part of the Melbourne to Echuca rail line, initially known as the Melbourne, Mt Alexander and Murray River Railway. George Christian Derbyshire, the first Engineer-in-Chair of the Victorian Railways was responsible for the design and construction of the works. No new lines were built in Victoria using double-headed rail after 1870. The siding was disconnected from the main line in 1988. The Ravenswood Railway Siding demonstrates the original 1856 philosophy of the Victorian Railways to adopt British permanent way technology. The siding demonstrates significant aspects in the development of permanent way technology in England and Victoria over the period from the 1830's to the 1880's. The chairs in the Ravenswood siding are physical evidence of early railway technology rendered obsolete 120 years ago, namely joint chairs at rail joints and trenails to secure the chairs to the sleepers. The double-headed rail demonstrates an important stage in the evolution of British rail technology in the 1830s. The old fish plates, square headed bolts and square nuts demonstrate the success of fishing the rail joins. The Ravenswood siding demonstrates the earliest form of rail joint technology developed in England, and existing in Australia, the joint chair. In part of the siding the sequence of joint and intermediate chairs is consistent with the 1856 specifications, that sequence is rare with the joints secured in joint chairs. The survival of chairs in this sequence is rare and almost certainly demonstrates that they remained in continuous use at the same location from 1862 to 1988. This remnant of the Ravenswood siding has survived 126 years. The siding has proved to be the most significant of extant remnant double-headed sidings in Victoria, containing a rare combination of early permanent way technologies. Construction dates 1862, Info from Ravenswood Railway Siding Victorian Heritage Database Report http://vhd.heritagecouncil.vic.gov.au/places/4693/download-report The remaining section of this siding is significant at the State and National levels in that it demonstrates the use of chaired rail by the Victorian Railways Department for the Trunk Lines and, more particularly, the following stages in the evolution of this long obsolete method of permanent way construction: a) The use of joint chairs and intermediate chairs at regular intervals inferring that the original wrought iron rail lengths were 12 feet, as is known through documentary sources to have been the case. The survival of chairs in this sequence is unique and almost certainly demonstrates that they have remained in continuous use at the same location and in the same sequence from 1862 to 1988 . b) The use of joint chairs and intermediate chairs designed for use with trenails. c) The use of later intermediate chairs designed for use with steel pins and the use of fished joints with steel double head chaired rail, representing a second method of constructing the permanent way using chaired rail technology. info from Ravenswood Siding - Melbourne/Echuca Railway Line - Victorian Heritage Database Report http://vhd.heritagecouncil.vic.gov.au/places/70103/download-report Addition to Citation for Melbourne to EchucaRailway Line 1/10/1990 Double Head Rail The surviving lengths of double head rail with chairs on this railway compare with one surviving similar remnant on the Geelong to Ballarat railway and are representative of permanent way construction techniques applied exclusively to the two trunk railways of the 1860's. In this respect they are rare survivors and may be unique at the national level and of technical importance at the international level to the extent that they enhance contemporary understanding of early railway building technology. Surviving lengths of chaired double head rail survive at Kyneton, Ravenswood and Bendigo on this railway and include a number of different types of cast iron intermediate and joint chairs with hardwood keys and metal pins. The Ravenswood siding is of special significance for the diversity of chair types and for the sequence of chairs recalling rail lengths known to be associated with construction of the line in 1862. Construction of the Railway Tenders closed on 24 March 1858 with no less than 133 tenders being received. A contract was let to Cornish and Bruce for £3,356,937 to commence work on 1 June 1858 and complete the line by 31 July 1861. Cornish and Bruce made quick early progress with the Melbourne to Sunbury section being officially opened on 13 January 1859. The line was officially opened to Bendigo (Sandhurst) on 20 October 1862 by the Governor of Victoria, Sir Henry Barkly. A great banquet was held for 800 guests and this was followed by a grand ball. The extension of the line to Echuca was a relatively simple matter as that part of the line was across plain country without any significant engineering challenges. Tenders were called for the work in 1863 and the work was completed in 1864 by contractors Collier and Barry Apart from the line contractors, other firms directly involved were J Shire law and Co (sleepers), R Fulton, Langlands Brothers and Co, William Crossley (water supply), B Moreland, Langlands Brothers and Co (platelayers lorries), E Chambers (iron pins, traversers), Miller and McQuinstan (luggage vans and steam engines) and various contractors for building works.

It was established on 8 February 1853 to build a railway from Melbourne to Echuca on the Victorian-NSW border and a branch railway to Williamstown. The company struggled to make any progress and on 23 May 1856, the colonial Government took over the Company and it became part of the newly established Department of Railways, part of the Board of Land and Works. The Department of Railways became Victorian Railways in 1859. Construction of the Bendigo line commenced in 1858, but this private consortium also met with financial difficulties when it was unable to raise sufficient funds, and was bought out by the Victorian colonial government. The design work was then taken over by Captain Andrew Clarke, R. E., Surveyor-General of Victoria, with bridge designs completed by Bryson and O'Hara The contract for the first stage of the line from Footscray to Sandhurst (now Bendigo), was let to Cornish and Bruce for £3,356,937.2s.2d ($6.714 million) with work commencing on 1 June 1858.
