Liverpool Street Station - Concourse and platform radio station

Train operator MTR Crossrail approached L.B. Foster Telecoms to design a bespoke radio microphone system integrated into Liverpool Street station’s existing communications infrastructure.

Introduction

Liverpool Street station nestles in one of the City’s leading financial centres. Stretching from Moorgate in the west to Broadgate in the east, the station’s new Elizabeth line ticket halls are connected by two mined platforms. Fully accessible ticket halls provide direct interchange with the Northern, Central, Metropolitan, Circle and Hammersmith & City lines, as well as National Rail services to Stansted and Southend airports.

The new Elizabeth Line Liverpool Street station will open in December 2018 when services begin through central London. When the route fully opens in December 2019, a train every two and a half minutes at peak time will allow passengers to travel all the way through to Paddington, Heathrow or Reading in the west and Shenfield or Abbey Wood in the east.

Train operator MTR Crossrail approached L.B. Foster Telecoms to design a bespoke radio microphone system integrated into Liverpool Street station’s existing communications infrastructure.

“Liverpool Street station covers a huge area so we needed a communications solution to allowed us to convey radio announcements without physically being in that part of the station. The team at L.B. Foster Telecoms designed, installed and commissioned a sophisticated new security solution that ticks all the boxes.”

Requirement

The legacy Public Address (PA) system at Liverpool Street station required upgrading to enable extended functionality, as identified by MTR Crossrail. The project’s objective was to enable remote radio announcements from existing PA zones to any other zone within the station’s perimeter.

Specification

  • Teleque Radio System solution
  • fully integrated solution into Liverpool Street’s existing station PA ASL system
  • installation of equipment nodes, receivers, multiplexers and antennae
  • commissioning and testing functionality to MTR Crossrail operational requirements
  • installation of all communication data cables Co-axial and Cat5e
  • installation of all low voltage (LV) electrical cables
  • installation on various CRMS systems

Our Solution

At the outset of the project L.B. Foster Telecoms undertook a detailed audit and analysis of installed PA equipment. This identified that the legacy radio system, part of the station’s PA system, did not have the functionality or capacity to deliver the extended performance capability.

Our solution involved upgrading to a new Teleque Radio System that was fully integrated into the station’s existing infrastructure, supported by additional peripheral infrastructure. This enabled radio PA announcements to be made across the station and to all zones, as required.

“What we look for in any project is expert advice and guidance. The team at L.B. Foster Telecoms delivered on all counts, offering experience and expertise that meant the final installed solution achieved exactly what was needed. What shone through was the team’s inherent understanding of the challenges we face in the rail sector and the ability to identify great solutions.”
