XiTRACK™ Projects: Kingussie
Bridges
Two
bridges on the Highland Main Line at Gynack and Balavil
near Kingussie are prone
to
flooding causing heavy ballast
contamination and potential wash-out, leading to track
defects, disruption and subsequent delays.
A XiTRACK scheme was devised for each of the bridge
transitions to help prevent ballast being washed out under
the sleepers during such periods of flooding. This gives
protection to the ballast under the sleepers permitting
any water to pass through the GeoComposite but allows all
forms of conventional maintenance to occur.
The XiTRACK Polymer was applied in ambient conditions of
-9oC, this being the lowest application temperature to
date, but the material behaved as expected. The jobs were
completed on time and each site now has proven enhanced
protection against ballast wash-out.
