We are a telecommunications integrator. We develop user requirements into robust design solutions across the spectrum of system technologies. We provide this for both underground and overground environments from complex integration at major stations to large linear systems across entire rail networks.

Case studies >

Technologies we work with include voice, acoustics, video, display, radio, telephony, networking digital and analogue data. We deal with new and old ensuring we can integrate one with the other.

We do not manufacture, supply or endorse specific products or technologies. This allows us to evaluate the market impartially providing the best advice and recommendations to our clients.

We engineer critical and non-critical systems embracing all the complexities of the railway including track access, station operations, staff duties, train operations, track and tunnel clearances, section 12 requirements, security, revenue collection, control of travelling public, passenger perception, listed buildings, station branding and ambience etc

How each system interfaces with another is a key part of our engineering. Often this is a critical risk the client holds. We add value by proactively managing interfaces held by 3rd parties such as asset agencies, other contractors, interfacing project teams, other design disciplines, PFIs etc. We do whatever is required to meet the client's overall objectives.
