Over recent months GEO-Instruments engineers have been conducting an array of essential monitoring works on Docklands Light Railway (DLR) tunnels in Central London.

DLR Nightshift Survey Team
The survey teams conduct levelling runs and 3D surveys simultaneously

Undertaken during engineering hours early in the morning, these comprehensive monitoring visits include Condition surveys, 3D monitoring surveys using retro targets, Levelling runs, and track geometry surveys using an Amberg GRP 3000 track trolley.

These multidisciplinary visits are an efficient way to gather vital information on Tunnel and track condition in the brief windows of time allowed by the busy transport network.
