consists of checking the geometric position of the rails for any changes that may be significant to cause a problem with the running of trains. It is imperative that track monitoring is undertaken whenever any work is carried out close to the tracks, where the track could possibly be affected.
Network Rail will normally insist that track monitoring is carried out, no matter how small the risk may appear. The main factor to be checked is any change in cant, which could lead to a serious ‘twist fault’. There have been instances where track monitoring has not been carried out sufficiently and serious derailments to trains have occurred, due to a twist fault developing.
Over 10 years of track monitoring experience
Our methods range from a basic cross-level to check cant & gauge through to sophisticated track survey trolleys, we also use Track Monitoring Targets supplied by Sentripod (www.sentripod.com
) as well as being able to manufacture bespoke target ourselves. As a company we have a wealth of experience and have been involved in track monitoring for over 10 years and have worked on a number of sites ranging from a 50m monitoring site for 3 weeks, through to a 5km monitoring site for 2 years.
