DH31 - DH59 Diesel Hydraulic locomotive Built to 3'6" gauge in 1970 this Diesel Hydraulic locomotive entered service for the Queensland Railways where it remained until withdrawn in 1994. Purchased by the E.T.R.B. in 1995, it was converted to 2'6" gauge in Queensland and transported to Belgrave in 1996 for overhaul. It re-entered service later in 1996, although instead of receiving a V.R. type classification & number and V.R. style livery, it retained its Q.R. number of DH59 and its Q.R. livery minus the Q.R. logo, but has since been repainted the traditional Blue & Gold of V.R. diesel locomotives and reclassified DH31. It has since been returned to DH 59. The DH class was a class of diesel-hydraulic locomotives built by Walkers Limited, Maryborough for Queensland Railways between 1966 and 1974. In 1966 Queensland Railways tested a Walkers Limited built diesel-hydraulic shunting locomotive. This was later purchased and by 1974 the 73 DH class locomotives had taken over shunting duties in most Queensland yards. They were also used on short distance freight services. With the closure of many freight yards and the move to longer trains withdrawals started in the 1980s. Many were sold for further use on Queensland sugar cane railways.

Part of a 43-photo record of the MMBW�s engineering feat in drilling a 12 inch pipe line up to 40 feet deep through rock hardened by volcanic action associated with geological fault that occurs along the line. The work took place from October 1979 to May 1980 on the southern boundary of Hubbard Reserve, North Ringwood. The collection was presented to the Ringwood Historical Research Group by J Clarke on 9th June 1980.E565 N10 28 April 1980 A43 The "muscles" of the mechanical mole, driven by a hydraulic line from a powerful "power pack".

Electro hydraulic dredge Snake Valley 1909. J Mc Bennett, was an engineer back at the main base, at Dawson's dam on the Carngham Road, Between Linton and Snake Valley. These dredges were used for getting gold. The streams of water under high pressure just washed the hills and ground away. This dredge closed down early 1910. 200 H.P. motors were used and 10 in. pumps.Black and white image of three workmen, one beside mining building the other two at dredge pump outlet. Image mounted on dark brown card. Between 1904 and 1911 the Electro Hydraulic Company sought to extract gold in an area north of Linton known as the Hard Hills. By blasting water from high-pressure hoses into the hillsides, soil containing gold was washed out for sluicing. Two gravel pumps in Dawson's Dam pumped the wash through the sluices. Despite considerable investment in expensive equipment, the Company did not have a great deal of success, and the mining operation ceased in 1911.mining, gold, mining equipment, electro hydraulic dredge, dredging, sluicing, dawson's dam, snake valley, miners

Zilles Printers was begun by Lewis Zilles in the early 1930s. It was in McKenzie Street Ballarat. His son Jeffrey also became a printer - letterpress, offset and screen printer. The business became Zilles Printers/Graphics and was in Armstrong Street and later Bell Street Ballarat. Munro Engineers were pioneers in farming equipment since 1800s. Their main product was a range of fencing machinery. In 1963 they invented and produced the world's first tractor mounted, hydraulic post driver with digger.
