Backlock is a Railway Engineering Consultancy that provides a range of specialist Railway Signalling and Engineering services. We focus on signalling, but also offer engineering expertise in all rail engineering disciplines and in the management of rail projects.

We specialise in signalling design, integration, acceptance and signalling engineering management. We have a detailed understanding of the Network Rail GRIP process and in obtaining the associated approvals. Our expertise in signal engineering includes; development of schemes, design and verification of schemes, design and verification of detailed design, product approvals, risk assesments and schedule recovery.

We provide temporary and permanent resourcing solutions to the industry. We have a track record of securing key resources that are vital to the implementation of projects.

We are able to operate in both UK mainline and London Underground environments and we have expertise and knowledge of delivering in both settings.
