Railway Signalling Services - Pearsons Engineering Services partnering Green Light Signalling

Pearsons Engineering Services Signalling team have successfully delivered projects for Bombardier Transportation over the last 18 months including:

1. Crossrail - Installation of DOO CCTV Equipment at RIDC Melton

Installation of a DOO CCTV system simulating the layout that could exist at a 2 platform station. The configuration comprises 2 DOO wayside cabinets positioned on concrete plinths and 2 DOO Leaky feeder cables suspended on either side of the track on a metal framework (Unistrut) dug into the ground. This recreates the position that the cable would be mounted on the face of a platform. Also included is one representative camera stanchion (Crossrail prototype version) mounted beside the track positioned as it would be on a real platform.

2. Crossrail - Installation of AWS/TPWS Equipment at RIDC Melton

Installation of 5 x Train protection warning system (TPWS) as per the Thales hand book number 13764 this includes TSS & OSS loop aerials track side enclosures, line side cables and tail cables. Location of equipment Old Dalby & Saxelbye.

Installation of 5 x Automatic warning systems (AWS) as per the signalling installation hand book NR/GN/SIG/11210 this includes Permanent magnets and electro magnets and all associated sleeper mounting equipment. Location of equipment Old Dalby and Saxelbye. Installation of the two control panels at Saxelbye and Old Dalby test track

3. Crossrail - Installation of European Train Control System (ETCS)

Installation of ETCS balises and control equipment at Melton test track. This was to permit representative testing of the Class_345 train in ETCS Levels NTC (both AWS/TPWS and CBTC), Level 1 and Level 2, including dynamic transitions between levels.

Documentation ref: Installation Specification 2010-1.4 DAA

All lineside installation was installed in accordance to the signalling installation handbook ref: NR/L3/SIG/11303. Disconnections boxes and signage marker boards were mounted on post & skates and post mix was used to fix them in place.

The installation of power supply units and the installation of power and control cables throughout both sites.

We have also carried out installation in the REB's as per the client's design. This project has allow Bombardier to test their system and allow for any changed require for further installation. PES staff have attended ERTMS training with Signet solutions covering Level 1,2 & 3. Our staff have been working with the client programming the balise and LEU equipment of and on site. After programming had been completed we tested the ETCS equipment to insure the telegram had been down loaded correctly.

All of the above projects have been installed to the client's design and are for the testing of their equipment at Old Dalby test track. Our recent project has included the installation of the balise units over a 3 mile section of the track.
