XiTRACK™ Projects:  Bletchley Site Treatment

   Bletchley S&C
The switch at Bletchley South was treated early in 2000 to correct vertical and lateral stability problems on this this high-speed section of the West Coast Main Line.  The site had been a major maintenance headache for some time with imposed speed limits until XiTRACK was applied.

“The XiTRACK-treated S&C site on the WCML to the south of Bletchley station has been performing without any maintenance attention or loss of alignment for over 3 years.  This has a freight turnout and is rated at 110mph, the maximum static axle load is 25T and the average traffic is 30MGT per year.

The long-term cost-effectiveness of XiTRACK treatment of this site compares very favourably with the pre treatment maintenance schedule costs.  The site was successfully treated by XiTRACK in March 2000 and since then no ballast maintenance or realignment work has been required at the site; no speed restriction has been applied to it.  Previously the alignment had to be corrected at least three times a year.” Carillion October 2003

This XiTRACK-treated site (now rated at 125mph) is still performing without maintenance or speed restriction more than seven years after application.

Bletchley IBJ
Following on from the successful performance for over four and a half years of the XiTRACK treatment of the Bletchley switch, a problematic IBJ was treated within the Bletchley South complex.

The IBJ had suffered vertical alignment problems after upgrade of the line to 125mph.  The XiTRACK treatment stabilised the ballast around the joint and it is performing as expected nearly four years later.
