1984 – Aug – Metcalfe – Low Cost CTC Alternative

Author(s):

Date presented: December 28th, 2015

AJ Metcalfe MIRSE DML Engineering (QLD) Pty Ltd in the intervening years between the two world wars C.T.C. systems were developed, basically as we know them today, giving all the advantages of secure block sections combined with the concept of overall control by one operator of a complete section of line as in the train order system. C.T.C. systems have one major disadvantage to modern railway administration, and that is the relatively high cost and generally, the continued use of many hundreds of kilometres of pole line which is expensive to maintain. In my talk today I would like to firstly consider how the cost of C.T.C. schemes for the more major routes could be reduced without losing integrity or flexibility of the system and then continue to low cost alternatives to obsolescent and labour intensive systems used on low density traffic lines.

1984 – March – Leclercq – South West Communications

G LeClercq Westrail The scope of the South West project was, in order of importance, to provide communications circuits for:- the signalling train control systems based at Picton: Picton to Coolup and Picton to Collie. the emergency telephones installed along the tracks and at the road crossings. Those circuits are all connected to the controller at Picton. the station masters to Picton Control (direct link). the connection of the controllers at Midland and Picton (direct link) the 2 VHF radio bases at Picton and Collie (later Cookernup) PAX phones installed as extensions on Bunbury and Collie exchanges. The existing overhead bearers in the area were inadequate to fulfil the new conmunications requirements and needed extensive upgrading. A cost study showed that, in the long term, a cable carrier system would be the most economical solution, and, furthermore would provide the base for a future upgrading of our communications network between Perth and Bunbury.

1983 – Aug – Pratten – A Railway Passenger Information System

Jon RD Pratten BSc BE Divisional Manager, GEC Digital, GEC Australia Limited This paper covers the passenger information display system at Sydney Terminal (Central) Station. The system was provided by the Digital division of GEC Australia Limited under a contract with the State Rail Authority of New South Wales. The system provides television monitor displays of train arrival and departure information for the public at various locations around the station complex. Displays are grouped according to the type of information they present and consist of: 15 platform displays (one per platform) each summarising on one monitor the service information of the train currently a1located to the platform. 10 concourse displays, each split into upper and lower portions on separate monitors and fully describing one of the next 10 departures. 2 sumnary displays, summarising separately the next 10 departures and the next 10 arrivals, repeated on a total of 8 monitors at appropriate locations around the station.

1948 – May – Stewart – Power Railway Signalling

Some Observations on English and American Practice Mr. F. Stewart (Member) A. S. T. C., A. M.I.E. (Aust.) Assoc. Inst. T., Signal Engineer, McKenzie & Holland (Aust.) Pty. Ltd. Modern railway signalling covers such a wide field that no single paper can adequately cover the technicalities involved, and this paper has, therefore, been limited to some observations on English and American practice in power signalling.Railway systems in England and America have had to meet widelv different conditions of population density and area, and traffic operating conditions in the two countries have been developed to suit the local conditions.Railway signalling in each country has been adapted to meet the varying traffic conditions and track layout, whilst retain- ing the accepted basic principles of safe working.We get some idea of these differences by comparing the long hauls on single track, with long and heavy trains, so characteristic of much of the mileage on American railways, with the shorter trains and short hauls on multiple track, which constitute the greater portion of English railways.
