DB Schenker Rail UK are seeking to save over 4,500 tonnes in carbon emissions every year through the introduction of stop-start technology to ninety class 66 locomotives
The trial has provided data which confirmed a reduction in fuel
consumption when the stop start technology is used, resulting in a lower
impact on the environment.
The technology, manufactured by ZTR, works in a similar manner to stop
start technology in a car, stopping the engine from running when
idling. Results showed that the amount of time the engine was running
was reduced by approximately one third. This would reduce CO2 emissions
by over 50 tonnes, equating to a saving of over 4,500 tonnes of CO2 for
the ninety class 66s that will be fitted with the technology by the end
of 2015 - approximately a 10% reduction overall.
The company also anticipates that the technology will help improve
reliability for customers. Tests indicate that use of the stop start
technology will reduce the number of flat batteries as well as
the potential for locos to freeze in cold weather conditions. All
relevant safety checks have also been carried out.
The rollout will commence this year with 90 planned to be completed before the end of 2015.
Andrew Byrne, Head of Maintenance and Infrastructure DBSR UK, said:
"The Auto Engine Stop Start technology (AESS) provides huge
opportunities to improve the environment impact of rail freight.
Although rail freight is a more environmentally friendly mode of
transport solution than road, we continuously seek to find ways in which
the impact of rail freight can be reduced further. We aspire to become
an eco-pioneer, and this project is a key part of that strategy."
