Objectives

Further develop and quantify benefits of the intelligent Train Monitor (ITM) in a range of locomotives and train types.

Background

In 1994 the Train Dynamics Group began testing of wagon and train dynamics on the Callemondah-Blackwater coal haulage system. In 1996 comprehensive testing of the whole track section for both empty and loaded trains was completed. This program included coupler force, inter-wagon and brake instrumentation on six hopper type coal wagons and two locomotives. A wealth of field data was obtained and analysed. This data was used to extend knowledge of train dynamics. The Train Dynamics Management Project was implemented in 1999 and has the overall objective of providing practical feedback paths into QR's operating practices that will realise the benefits that continue to accrue from the Train Dynamics research. One concept arising from this research was the provision of a driver feedback device to increase the information available to the driver when operating long unit trains. This device has been called the intelligent train monitor (ITM).

The Intelligent Train Monitor(ITM) is an in-cabin device that provides the train driver with additional information regarding train stability and energy consumption.

The device is unique in that it also gives predictive information allowing optimal train controls to be selected and driving to be improved. It is estimated that energy savings after implementation could be as high as 15%. Savings to be realised in longer rollingstock life are yet to be evaluated in track testing, but conservative estimates from simulation studies suggest savings at similar levels (15%).

Outcomes

The first Intelligent Train Monitor prototype has been developed and installed. It is proposed to further test and develop this unit and build three other units to give a wide scope of testing and allow suitable hardware to be evaluated and compared.

Remaining works consist of finalisation of the user interface, documentation of benefits, pre-production evaluation of hardware and generalisation of the design to suit several different locomotive installations. It is proposed that this work be completed with collaborative arrangements between QR National and the Centre for Railway Engineering, CQUniversity.

The benefits come from improvements in driver training and hence train handling, as well as reductions in the costs of energy, maintenance and training. Overall, the Train Dynamics Management Project will reduce the cost of running trains.

Benefits to Queensland will include retention of expertise, energy savings in railway operations, export income from overseas sales and enhanced reputation as a leading rail innovator.
