South Wales Branch - Automated Rail Track Inspections

May 9, 2018 · Cardiff, United Kingdom

Automated Rail Track Inspections – using trains equipped with a wide range of detectors to capture information about the state of the track

Speaker: Iain King

Network Rail collects asset related data using a fleet of infrastructure measurement trains.  The data is fundamental to the safety and asset management of the railway, underpinning Network Rail’s approach to efficient and effective safety and asset management.  The fleet uses complex measurement technology (e.g. lasers, ultrasonic probes, ground penetrating radar and HD cameras) integrated with accurate positioning systems to collect asset related data to tight measurement tolerances.  Network Rail’s asset base includes approximately 2,500 stations, 22,000 miles of track, 40,000 bridges and tunnels and 26,000 switches and crossings.


The Infrastructure Measurement fleet comprises 13 trains formed of 64 carriages.  It covers 550,000 data mile every year.  There are currently 18 different types of condition measurements (data streams) which generate up to 1.3 petabytes of data each four weeks.  Depending on the measurement being taken, the trains can travel at up to 100 miles per hour whilst measuring.  The data is collected, analyzed and distributed to local maintenance managers.  The analysis is used to plan appropriate maintenance.


The presentation will describe both the technologies and how they are used to improve the safety, reliability and cost of the railway.


This is a joint event with IET.
