RUNNING water will be used by Balfour Beatty Rail Technologies to demonstrate the way its XiTrack geocomposite ballast treatment forms a three-dimensional polymer cage around ballast.

It does not fill the voids, so allowing water to drain through. The polymer accepts track movement under passing trains, rapidly returning to the desired alignment (RG 11.04 p770).

Also displayed will be SA-380 data logging and event monitoring equipment, which it is hoped will be linked to a live worksite. n
