Installation of a DOO CCTV system simulating the layout that could exist at a two 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.
Installation of 5 x Train protection warning system (TPWS) as per the Thales hand book. This includes TSS & OSS loop aerials track side enclosures, line side cables and tail cables. Location of equipment Old Dalby and 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.
Two control panels were installed at Saxelbye and Old Dalby on the test track to allow our client to locally operate the signalling equipment. We also provided power supply cubicles with heavy duty cable to power up the TPWS & AWS units. Transforming the 415volts AC down to 50Volts DC.
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.
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 & stakes.
We have also carried out installation in the REB’s as per the client’s design. This project has allowed Bombardier to test their system and allow for any changed require for further installation. GLS 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 and were receiving the correct CRC codes.
We have been successful in securing a number of contracts to provide the above service to customers. Work has been carried out at depots in Liverpool, Nottinghamshire, Derby, Coventry and London.
Green Light Signalling ensure that our client’s sites are maintained to Network Rail standards and procedures. Our packages include pro-active maintenance, which prevents the reoccurrence of signalling failures. Regularly visits by the GLS team provide the reassurance that the infrastructures are fit for purpose and enables a more cost-effective approach for the client.
We provide fault cover including a 24 hour call out operation to respond to any immediate issues relating to interlocking systems or track side failures.
GLS are experienced in working on the following systems:
Mechanical interlocking
Route relay interlocking
Solid state interlocking
Electrologics interlocking
We were approached by Peel Ports to design a safe operational road level crossing in order that trains and cars could use this very busy junction. The challenge was to allow large vehicles to cross this junction from four different directions. This was achieved by installing extended booms and additional road traffic lighting. The crossing is activated manually by the rail staff as and when required. We employed a team of people who were able to provide the required skills, such as civils, barrier installation teams, skilled electricians and earth excavation contractors to complete the project to the client’s satisfaction.
The depot has recently been upgraded to facilitate the maintenance and servicing of the new Crossrail trains. A new signalling system has been installed and GLS are responsible for the maintenance and up keep of this system. This involves regular pro-active maintenance and ongoing testing to ensure the system runs effectively. GLS staff are trained on the electro logic system which is new to the railway industry.
