UniSA, TMG Rail Technology and Pacific National personnel discuss
the benefits of the developed FreightMiser system.

The FreightMiser system, created by a collaborative Rail CRC
research team at University of South Australia and TMG Rail
Technology, provides long-haul train drivers with an in-cab advice
system to assist them stay on time and minimise fuel consumption.
Traditionally, railways rely on the skill of their drivers to keep
trains on time without excessive energy consumption. However, with
conditions and drivers varying from one journey to the next, there
are considerable variations in journey times and fuel consumption.
The task is made more difficult by the fact that drivers have
little information to assist them to assess the progression of the
journey, in terms of time and energy consumption.
The ‘FreightMiser’ system provides for efficient usage
of fuel, while maintaining schedule. Instead of wasting energy
through driving too quickly and arriving head of schedule, the
on-board advice system advises the optimum speed profile for
drivers to reduce energy consumption while maintaining their
schedule.
Testing on industry trains showcased fuel savings of between five
and 20 per cent, without increases in journey times. Other benefits
included reduced wear through reduced braking requirements and
smoother train handling, via increased coasting and reduced
powering.
The system utilises a simple train interface and does not require
extensive onboard or trackside hardware. It includes a portable
data logger that uses a GPS receiver and an interface to the train
to log location, speed and notch setting, and development of
software that estimates fuel consumption from the data logs. The
technology is being further developed as a portable unit which can
be used by rail operators for specific train crews where necessary.
Evaluated by STEM Partnerships in 2006, the technology was
estimated to have the potential to deliver a risk-free-value to the
rail industry of $19.8 million over the next 15 years. Taking into
account the risks associated with delivering the technology the
estimated value was $15.2 million. Rail Innovation Australia will
work with TMG Rail Technology to facilitate commercialisation of
FreightMiser in Australia and overseas.
