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

Technology/Research:
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.
Status:
Today TTG (formerly TMG Rail Technology) and RIA have partnered to
accelerate worldwide Freightmiser sales. Securing preliminary
interest from a number of potential partners early in 2009, RIA and
TTG have progressed negotiations and expect to enter an agreement
in the near future.
Product trials by potential customers in Australia, Europe and Asia
were successfully undertaken in the 2008-09 year, with positive
feedback on fuel reduction and time compliance.
