XiTRACK™ Projects:  Harford

In 2003 the XiTRACK technique was used at Harford to laterally reinforce and stabilise a series of conjugated transitions on to typical direct-fastened timber deck bridges which are situated on a weak embankment and curves.  XiTRACK was selected as conventional methods had failed to solve the persistent lateral track geometry faults that occur with this combination of factors.  Such sites are often considered ‘unmaintainable’ as it is common for the fault to quickly return after maintenance or, as in this case, shortly after renewal.

XiTRACK treatment removed the persistent lateral track faults around these transitions where tamping is difficult or impossible and no lateral re-alignment has been needed since the application.

The treatment area was adjacent to a river and all requirements of the Environmental Agency were met.
