XiTRACK™ Projects:  Tottenham South Junction

A range of tailored XiTRACK Polymers was applied to ballast at Tottenham South Junction (Tottenham Hale side) in 2005 to incorporate vertical and horizontal XiTRACK reinforcement in the transitions around the steel-deck bridge.  This complicated site on the important route to Stansted Airport was prone to geometry and alignment problems in the transition area of the bridge and around the associated switch; frequent attention to the track and ballast had been necessary for a long time. 

A complex scheme of vertical and lateral XiTRACK reinforcement of the transition area was designed to improve the performance under local heavy passenger and freight loading and particular attention was paid to the ballast on the bridge deck itself near to the point machines.  Treatment took place during a planned track renewal period and did not impact on the timing of this, tamping was carried out the the installed site - the XiTRACK Treatment was especially designed to allow conventional maintenance as this was a specified factor in the job brief.

The site has performed as expected.
