Train operator one railway is to make rail travel more
environmentally friendly, with the completion of testing on its fleet
of Class 360 Desiro electric-multiple unit trains, to enable the introduction
of energy-efficient "Regenerative braking" or Regen
as it is usually known.
This green initiative allows the 360s to generate electricity
whilst they are slowing down, by converting the energy created as
the train brakes back into electricity - which is then passed back
into the overhead power system, thereby providing electricity for
these trains or others using the network.
The environmental benefit of this initiative is a reduction in the
amount of electricity used and therefore overall energy consumption.
Estimations suggest that it could result in a reduction of as much
as 16% in electricity use from the operation of the Class 360 fleet.
This is possible because the Class 360 Desiro trains use a modern
3-phase AC traction motor system. It also reduces the effect of friction
braking which reduces brake wear and cuts down on brake dust levels.
The 21 x Class 360 Desiro four-carriage electric-multiple unit trains
were originally designed to use Regenerative braking.
However, the infrastructure in the region was initially not fully
compatible with its operation. Recent upgrades completed by Network
Rail have now enabled one railway to make use of this
So far, nine of the Class 360 fleet have been "switched on"
for Regen and the remainder of the fleet will follow with
completion expected by the end of January 2007.
Dominic Booth, Managing Director for one railway said:
Customers rightly expect us to ensure rail travel is as green
as possible. The introduction of regenerative braking on our Class
360 fleet of trains is a major step-forward in reducing energy levels
to provide a far-more efficient and environmentally friendly method
of powering this type of train. one railway is one of
the first train operators to implement such a project, which is part
of our overall strategy to manage energy use in a sensible and considerate
