Walk Mill Cess Support

The site at Walk Mill comprised of a 10m high steep embankment that had a high ballast shoulder over a length of approximately 300m.
This section of line was classed as “at risk” of having continual ESR/TSR due to potential alignment issues caused by the lack of a compliant cess and ballast retainment issues on the shoulder.

The contract was for the design and construction of a cess retention system and a safe cess walkway.

The cess and ballast were held back by the installation of 7m long H-Piles at 1m centres along the crest of the Down Cess. Between the H-Piles hardwood timber was used to retain the ballast. A new handrail and a new cable route were introduced along with a safe cess walkway.

The four week contract was carried out during the Holme Tunnel Blockade, in February 2014. Whilst this provided welcome midweek working it restricted access to the site, in order to overcome the access issues TRS worked closely with the Maintainer and shared a small access point some 5 miles from the site allowing all the material to be transported during Saturday night possessions, in sufficient quantities to keep the gangs busy during the week.

The contract started on time, finished on time, was delivered within budget and with zero accidents.

Dave Thomas, AMCO Senior Project Manager said, “This was a tricky scheme with the potential to go wrong, particularly with the access point so far away from the site. Credit to TRS, they managed it so well that it was never on my radar which allowed me to give full concentration to the Holme Tunnel Reconstruction”.
