British Rail Network
'SouthEast' were faced with an unusual problem at
a project they were handling for Rail Freight.
At the new freight inspection yard
at the UK end of the Channel Tunnel, which is designed
solely for electric traction, the operators will initially
be using heavy diesel locomotives. When stationary
these were considered to be a high pollution risk
and it was therefore necessary to prevent any ground
contamination form leakages.
The special products division of
Oil Pollution Environmental Control ltd. designed,
manufactured and installed a total of 135 metres of
on-track trays to capture any leakages of fuel or
lube oils greases which may occur either between the
running rails or from the overhang outside the track.
OPEC's RP18 adsorbent fabric is
used to retain the oils and the tiered construction
of the trays allows rainwater to bleed off at regular
intervals through RP18 filter packs. The use of GRP
construction ensures durability and the design is
such that no tools are required when periodic maintenance
is carried out.
The alternative solution to 'Tricky
Track' would have been to install an extensive and
very expensive underground drainage system costing
in excess of 20 times that of Tricky Track.
