A telegraph or Morse key, sends a series of electrical signals down a telegraph line or via radio frequencies; the signals are interpreted as Morse code, a binary form of language constructed of 'dots and dashes', combinations of which correspond to letters of the alphabet. The motion of the key acts to complete an electrical circuit between the sender and receiver, producing a short pulse 'dot' or longer 'dash,' the space between the code indicates a broken current or wave.Device used to transmit telegraphic messages in Morse code through the manipulation of electric signals. The metal 'key' sits in a central bracket on which it moves up and down aided by a spring, controlled by an operator pushing the black Bakelite knob on the protruding end of the device. The motion presses the key onto a circular metal disc, completing the circuit and sending an electrical pulse to the receiver. The apparatus is secured to a wooden base with wires attached to the terminals; a cut out section of the base suggests wires may have entered through this area, attaching to a battery.Printed ink on base: "PMG"telegraph, telegraphist, morse code, mechanisation

Little has been written previously about this technical group of men and women and that their duties were under insurmountable difficulties which they faced and overcome in conditions that were encountered in the desert and jungle warfare. Without their constant and never ending services, the task of the force in bringing to a close this fight for freedom would have been greatly handicapped.An outline of the Australian Signals Corps over the years from the campaign in the Middle East to the present day of the victories in New Guinea.

This hand-held signalling lamp could have had a number of uses. It could have been used by groups such as the Boy Scouts or most likely was used by local air raid wardens and other military personnel in World War Two. Its large face and the reflecting mechanism would have made it useful over a long distance.This lamp is of historical interest and is retained for display and research purposes.This is a cylindrical metal lamp with a clear glass front attached to the lantern by metal screws. The lantern has been painted black. There is an electric bulb behind the glass and a reflector disc behind the bulb. A handle, attached to the metal body, has two strands of electrical wiring at its end. The handle includes a finger clip, which, when pressed, produces a signal inside the glass area.signalling lamp, world war two military equipment

The Fred Rochow Railways Collection incorporates photos related to the operation of the Wodonga Railway Station including different types of trains and railways staff C. 1930 – 1990. It was donated to the Wodonga Historical Society by Fred Rochow, a railwayman who spent many years based in Wodonga. He joined the Victorian Railways on 17th June l947 and retired in 1988. For some time, he was a member of the Australian Federated Union of Locomotive Enginemen and served a term as a member of the Trades Hall Council. He had an extensive knowledge of the struggles that took place to achieve better conditions for railway workers. Fred worked for many years as a fireman and then worked his way up the ranks to driver, experiencing many changes from the days of steam locomotives through to diesel trains, locomotives and even the modern XPT train. He worked throughout Victoria at different stages of his career, with his final working years focused on the northeast of Victoria and the Albury to Melbourne line. After his retirement, Fred continued to share his love of steam miniature trains with the community.This collection has local and statewide significance as it captures images of trains, locomotives and personnel who operated the railway services in Wodonga and throughout Northeast Victoria. The railways played a critical role in opening up Victoria and connecting Australia for trade, business, social communication and transport.Signalman Alan Neviandt descending stairs at Wodonga Signal Box A on 24 August 1988.fred rochow, steam locomotives australia, len gregson, david naldrett, train drivers wodonga
