DH5 Diesel Hydraulic locomotive 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.

Cocks Pioneer nozzle working. Cocks Pioneer Electric Gold & Tin Mine Company was formed in 1899. The company's first power station, located at the eastern end of the valley began operating with its 340 Kilowatt steam-powered generator. By 1909, from 2,500,000 cubic yards worked, reported recovery was 17,284 ounces of gold and 224 tons of tin ore. By 1909, Cocks Pioneer’s power plant had become inadequate and uneconomical. The barge was floated downstream about a mile, but lost time caused the operations to cease. Following testing, a new mine was established by diverting Reid's Creek at a cost of £25,000. Settling dams were built, one of which held 1,935,900 cubic feet. Sold earth banks, built against a wall of stringy bark saplings constructed and laced with vertical props, were built. In 1914, the company was reformed as Cock’s Pioneer Gold and Tin Mines NL, another power station was constructed at the western end of the township, near the junction of Clear and Reid's Creeks. From 6,800,000 cubic yards of material processed, the returns were 64,397 ounces of gold and 855 ton of tin. Cocks Pioneer mine then moved the barge downs stream and continued sluicing. In 1929 Cocks Pioneer Electric Gold and Tin Mining Company ceased operations due to a drop in values. Cock’s Pioneer Gold and Tin Mines NL carried on large-scale hydraulic sluicing operations until 1941. mines, mining, miners, men, gold, tin, gold mining, tin mining, hydraulic, cocks pioneer, el dorado, eldorado

Rail Bender - Part of Hydraulic Rail Bender Rail Bender – No. 3 Most rails are produced straight. While they to easily bend and appear flexible, they are required to bend for some curves, at rail joins on curves and at point (turn-out) junctions. For a safe transition around curves and in the finer areas of the point, this use to be done with a manual rail bender. Sometimes referred to as a Buddah, the rail bender attaches its two claws to the rail. In the middle of the two claws is a screw that is tightened slowly using large spanner.

This book contains letters and mathematical computations on hydraulic engineering. The material has been compiled by Arnold Lilley (Lilly), an Oxford mathematician working in Victoria in the 1890s. It is said that he taught or coached 95% of the municipal surveyors in Victoria in the 1890s. The book came from the office of one of Lilley’s pupils, John William Crawley Junior, an engineer, surveyor and architect with a private practice in Warrnambool and also the engineer for the Shire of Warrnambool from 1895 to 1935. It is presumed that he had the letters bound in book form. The book passed to his son, Rolf Crawley, the engineer for the Shire of Warrnambool from 1935 to 1968. It later came into the possession of Michael Hand who took over the private surveying business of Rolf Crawley in Warrnambool. The Warrnambool and District Historical Society acquired the book, along with other Crawley ledgers, from the estate of Michael Hand.This book is of interest as a memento of the 1890s teachings of the mathematician, Arnold Lilley and also of his pupil, John William Crawley, the engineer for the Shire of Warrnambool for 40 years.This is a blue hard-cover book containing handwritten letters and computations. There are some loose pages and some pages have postal stamps on them. The book spine is slightly scuffed. ‘Letters on Hydraulic Engineering by Arnold Lilly Esq Mathematical Coach. J. Wm.
