The project was a great success and completed in record time and to budget.

With a deep understanding of the railway environment and the latest telecoms networking technologies, Stuart’s project management and engineering experience provides our clients with excellent all round advice and guidance and is well versed in obtaining necessary consents and approvals associated with station change.
