A: This Highways Agency project involved the refurbishment of the complete lighting system for this busy twin bore 700m tunnel, located at junction 25 of the M25 motorway. Each tube houses up to 4 running lanes and an emergency lane, all being illuminated by 2943 No. ceiling mounted 2816 series luminaires using HID lamps. The lighting designers paid particular attention to the taper in the carriageway due to the on and off-slips. Control and monitoring is provided using the B-Scout system with a B-ScoutMaster in each bore being connected to the tunnel supervisory SCADA system.

A: This 1,200m tunnel has undergone a complete lighting refurbishment which included over 300 ceiling mounted 2815 series luminaires arranged in single, twin and quad lamp versions. Fluorescent lighting was adopted for the basic night and day lighting requirements with the boost lighting being provided by HID sources. The B-Scout system was the preferred choice to provide the control and monitoring of the lighting, with the system integrating seamlessly with the main SCADA system.

A: As part of an ongoing program of works, three urban tunnels have thus far been refurbished to include HID and fluorescent lighting provided by ceiling mounted 2816 series luminaires and cornice mounted 2815 series luminaires. The B-Scout control and monitoring system has been adopted with each system being permanently connected to the Birmingham City Council street lighting offices where the i-TunneL® MasterLink™ supervisory software provides automatic remote monitoring and control functions.

A: At nearly 400m in length and having three running lanes (one of which providing for tidal flow traffic schemes) this Highways Agency tunnel provided some unique challenges. The new lighting was provided by a combination of fluorescent and HID light sources housed in over 200 No. cornice mounted 2815 series luminaires supplied as single, twin and quad types. The B-Scout control and monitoring system was employed to marshal the lighting levels and provide the necessary system status information to the maintenance teams.

A: Representing the most complex tunnel lighting project undertaken by WRTL, the Sodra Lanken tunnel as the name suggests forms part of the ‘Southern Link’ road around Stockholm, Sweden. The tunnel consists of 4.5 kilometres of bored tubes with 11 entrances and 16 underground intersections. Both 2815 and 2816 series luminaires were used with a combination of fluorescent types cornice mounted, and HID types with counterbeam optics. Following the successful completion of the project in early 2006, Anders Ingels of the contracting company Tunnel Entreprenad had this to say “WRTL’s commitment & professionalism enabled us to provide the best solution for this prestigious project. We regard WRTL as a key partner in our success.”

A: Having three running lanes, one emergency lane and a separate local access road, this wide 110m tunnel presented particular problems as the lighting could not be mounted over-lane. A unique solution of using twin HID counter-beam 2816 luminaires mounted at 90° to the road provided the solution by efficiently distributing the light across the carriageway. The B-Cub system provides the control of the lighting with remote access provided via the GSM mobile network.

A: This 4.5km twin bore tunnel is the longest tunnel in Ireland. It represents a vital link between the port and the motorway network, relieving the City Centre of vehicles travelling to and from the ferry terminals. The 2816 series luminaire with HID light sources is used throughout the tunnel to provide the complete road lighting requirement.

A: The Dartford tunnel is situated at the Kent/Essex borders of England and connects the north and southern sections of the M25 London orbital motorway. WRTL were selected to design and supply a new lighting system to comply with the latest BS code for both the west and east tubes. A combination of fluorescent and HID light sources were used housed in 2815 series luminaires of varying lengths from 2.4 to 4.8 metres, providing a fast installation on this time-critical project.

A: This project involved the conversion of a disused railway tunnel for the use of bi-directional traffic in order to relieve congestion in the centre of Caernarfon, one of the main tourist destinations in North Wales. The lighting was provided by ceiling mounted four-lamp 2815 luminaires using a combination of fluorescent and HID lamp types. The B-Scout system provides the control and monitoring of the luminaires.

A: This project included the lighting of two tunnels on the new section of the A1(M) motorway near Darrington. Both the Holmfield and Longbull structures were illuminated with an over-lane lighting scheme using symmetrical 2816 luminaires with HID lamps, coupled to a B-Cub control system which links to a remote location via the internal GSM modem.

A: This project included the refurbishment of the existing tunnel under runway 1 and the installation of lighting into the new tunnel under runway 2. Both tunnels were provided with multi-lamp 2815 series luminaires mounted in the cornice using fluorescent lighting for the basic stages and HID for the boost levels. The new tunnel adopted the B-Scout system to provide full control and monitoring of the lighting, directly interfacing with the airport SCADA system for remote control and status reporting.

A: Representing one of the busiest underpasses in Europe the Charing Cross tunnel allows the M8 to pass under the heart of Glasgow. Four metre long multi-lamp 2815 luminaires were supplied to enable fast installation to the mounting infrastructure using HID lamps. The B-Scout control and monitoring system was adopted to provide fully automatic control of the system which is also accessible remotely via the installed PSTN line.

A: This tunnel evolved from the A50 upgrading works easing traffic flow in the area. 2814/5 series luminaires were supplied, incorporating fluorescent models for the night time and basic day time requirements, and HID for the boost lighting. As a one-stop-shop facility, the approach road lighting was also supplied as part of the contract.

A: This 600m long twin tube tunnel crosses the river Lee, forming a critical link in the Cork ring road. 2814/5 series luminaires were supplied, incorporating fluorescent models for both night time and basic day requirements, and HID for the boost lighting.

A: This tunnel provides for the passage of traffic under the new Doncaster Frenchgate Interchange Centre and is formed from two 160m long square tubes, one of which has an internal intersection. Lighting is provided by 188 No. twin and quad lamp 2815 series luminaires mounted in the cornice with a mixture of fluorescent and HID light sources. Nearly 700 No.B-Scout1 units provide the monitoring and control of the luminaires, governed by single B-ScoutMaster controller.

A: This 300m tunnel required both counterbeam and symmetrical lighting with linear fluorescent and high pressure sodium lamps, totalling over 500 luminaires. Due to strict timescales, prompt delivery of the project was paramount. On successful completion of the project, WRTL received formal thanks from the ultimate client for adhering to the stipulated delivery regime.

A: This newly bored, twin bore tunnel sitting at over a kilometre in length, required lighting in accordance with the strict Swedish standard. To achieve this, the WRTL twin lamp 2816 luminaire was adopted for the lower level lighting to allow simple control without dimming. High pressure sodium lighting was employed throughout together with the 2816 luminaire to operate in conjunction with the existing control system.
