NR Scotland opts for ‘precise’ 3-D imaging

NETWORK Rail Scotland is now using a track-based, three-dimensional scanner to quickly and precisely model its infrastructure ahead of the arrival of new trains.

The Trimble GEDOScan system – operated by Network Rail’s team of absolute track geometry (ATG) engineers – has been deployed to collect detailed information about the track and surrounding features such as bridges and platforms, quickly gathering precise, high-resolution data for use in track-clearance assessments on structures and tunnels.

The new system was introduced in April and is delivering higher-quality images more quickly and precisely than was previously possible. It also increases safety for engineers, who can gather much more detailed data while spending less time on the track.
