Rollingstock bogie assembly and weighing station

Following a number of unexplained derailments of Electric Multiple Unit (EMU) Trains in Sydney and also the rapid settlement of the rubber springs installed on Tangara Cars, State Rail specified that all cars were to be weighed and balanced following bogie replacement. Research showed that although there were devices available throughout the world for weighing cars and bogies, these did not meet the requirements of State Rail or the maintenance workshops in achieving the desired result. To meet State Rail specifications, MainTrain, which is contracted to State Rail for EMU Car Heavy Maintenance initiated a project to research and develop a bogie assembly and weighing station that would meet all production requirements and achieve specification. A unique wheeling and weighing station for bogies has now been built and installed in the MainTrain Bogie Shop with excellent results, and has set the standards for accuracy and consistency in bogie balance. All cars now released from MainTrain meet State Rail Specifications in regard to weight and balance. This paper presents a description of history behind the development of the machine, concept, design and manufacturing process, results of the review and potential benefits. The main conclusion of this work is an improved understanding of the weighing process, parameters to which the car weighing performance is sensitive and a basis for evaluating and manufacturing alternative designs.
