Agencys tenth birthday was celebrated in an unique manner on
Thursday 7 September at Bristol Temple Meads station, when First Great
Western High Speed Train power car No. 43097 was named after the environment
Environment Agency Chairman Sir John Harman was invited to unveil
the cast nameplate including the Environment Agency logo by
First Great Western Managing Director Alison Forster in recognition
of the agencys role in managing the effects of climate change
and because of its long connection with Bristol where its HQ is based.
We are committed to showing businesses and organisations how
they can reduce their negative effects on the environment by supporting
public transport whenever they can, said Sir John. This
goes hand in hand with our own pledge to halve our transport emissions
within five years.
The Environment Agency power car is more environmentally-friendly
than its predecessors and is powered by the new MTU 16V 4000 engine,
proved in service to deliver exceptional environmental benefits. It
is one of a fleet of 117 power cars which will be fitted with the
new engines by the end of 2007. They offer greater efficiency, quieter
engines and significantly lower emissions. In turn these will improve
performance and reliability for our customers across the south and
west of England, the Cotswolds and South Wales, said First Great
Western Managing Director Alison Forster.
First Great Western carries more than 70 million passengers each year
between 202 stations. The project to replace its fleet of power cars
started in 2002 with the evaluation of several engine types suitable
for fitting to its High Speed Trains, with emissions a key success
Trials started in 2005 with two power cars (43004/009) being re-engined
and put into daily service. To date they have delivered more than
10,000 hours reliable running and shown they deliver environmental
benefits, including lower emission levels, in line with current European
legislation, and with the potential of meeting the next Stage 3a requirements.
Environmental benefits include:-
* 15 percent lower fossil fuel consumption with no loss of delivered
* Carbon dioxide emissions down 64 percent @ 1.2g/Kw hour
* Nitrogen oxide emissions down 21 percent @ 9.5g/Kw hour
* Hydrocarbon emissions down 46 percent @ 0.75g/Kw hour
* Smoke emissions down 42 percent @ 0.8g/Kw hour
* Particulates down 16 > 75 percent @ 0.25g/Kw hour
* Considerable reduction in lubrication oil consumption equal to 76
percent over existing Valenta engine, with recyclable potential equal
to 14.5 tonnes (12,747 litres) per engine year. When the fleet fitment
of 117 engines is complete this will equal 1,696 tonnes (1,491,339
litres) per year.
* Increased engine overhaul life from three years to five years, reducing
energy requirements to overhaul and parts consumption.
* Reduced vibration levels, improving the drivers environment.
