February 22nd – Passing through Telford on a flying visit in the morning, I noticed that the worksite for the new footbridge was oddly quiet. It seems test bores have been completed and are now being monitored for effects on the nearby built environment – including the railway itself.

Along the rails are mounted at intervals surveying datum targets which will be monitored – either manually, or by use of an automated theodolite – to see it recent operations are causing any movement.

A fascinating use of technology.
