Objective
Amongst environmental issues that represent major
constraints for European Railways, noise generated by
freight traffic is one of the most important and
difficult to solve. Freight traffic is operated as much
at night as during the day, and noise levels imposed by
legislation tend to be particularly severe for this type
of traffic. Noise emitted by freight traffic is the
result of interaction between freight wagons, belonging
to a wide number of Companies all over Europe and
neighbour countries, and national infrastructures This
makes solutions especially difficult to apply, and
require a joint effort at European level.
Although ground based protection such as noise barriers,
or buildings improvement. will remain locally necessary,
a reduction at the source is indeed more efficient, when
achievable Reducing freight traffic noise at its source
requires combined action on both track and wagons.
Therefore, (( Silent Track )) project clusters closely
with the BRITE EURAM 'Silent Freight' project, BRPR
CT95 0047, started in february 1996, which concentrates
on solutions for interoperable rolling stock
The objectives of (( Silent Track )) are to develop a
number of innovative technical solutions to be applied to
existing tracks, and also to new infrastructure, allowing
to reach, together with a combined action on vehicles, a
global reduction of noise emitted by the train/track
system by about 10 dB(A) The cost of implementing these
solutions, by retrofit on existing tracks, or from
building stage for new ones. must remain reasonable,
that is significantly lower than the cost of a noise
barrier.
Work will include development of investigation and
simulation tools, design and validation of solutions.
with a strong emphasis on the understanding of phenomena
governing rail roughness, the optimisation of the design
of track components ( rail, fastening systems,
sleepers...). It will be concluded by a demonstration
exercise coordinated with Silent Freight where prototype
solutions for wagons and track will be jointly tested,
shonwing achievable noise reduction and allowing an
extensive validation of new models. Guidelines ill
been producec in view of standardisation and of defining
a policy for the implementation of low noise design in
Europe.
The project will be carried out by a consortium
coordinated by the European Rail Research lnstitute (ERRI
), a body in charge of RTD for all European Railways, and
including several manufacturer, of rails. fasteners. pads
and other components. and several Research Centres.
