York Central Development: Assessment, Recommendations and Design
As part of the initial stage of the £1.1bn York Central Development, which is to include the creation of the UK Rail Innovation Hub, AGHE were commissioned by Network Rail to produce a detailed survey and recommendations report for the HV, LV, signalling power, domestic power and security services, serving both York Integrated Electric Control Centre (IECC) and York Regional Operations Centre (ROC). Following on from the submission of this report, AGHE were commissioned to produce detailed designs for modifications to electrical distribution systems within the development site area, York IECC and York ROC to enhance the autonomy level for power of critical supplies and to cater for the York Central Development physical works.
Selby and Hull River
Swing Bridges
AGHE were commissioned by Network Rail to undertake detailed electrical, mechanical and lighting surveys and produce detailed designs for the major refurbishment of Selby Swing Bridge. The bridge is one of several on the UK rail network that are positioned over water and swing or slide open to allow boats and ship traffic to travel safely through. The design included for the installation of new UPS system for critical bridge operation systems, specially rated lighting for the river area environment and full electrical distribution system renewal. Subsequent works undertaken on railway moving bridges include Keadby vason/sliding bridge, Goole and Hull River Swing Bridge. As part of a major refurbishment at Hull River Swing Bridge, AGHE have produced designs for new lighting, small power and bridge movement controls.
East Coast Digital Programme: Northen City Line Signal-Free Digital Railway
As part of the UK’s first operational route of signals-free infrastructure, this project implemented the digital signalling system known as ETCS (European Train Control System), from Moorgate to Finsbury Park on the Northern City Line. This was part of the £1.4bn East Coast Digital Programme and sees the removal of traditional line side signals and the use of in-cab train computers and a new line side digital signalling system. Following on from previous works undertaken in the Northern City Line which included emergency lighting controls, water pumping systems and the refurbishment of Drayton Park Substation, AGHE undertook detailed surveys of the electrical and mechanical systems within this special tunnel switch room environments and produced detailed signalling power distribution designs for the scheme.
Eaglescliffe Railway Station
Redevelopment
This multi-million pound project oversees the complete refurbishment and expansion of Eaglescliffe Railway Station which is a key strategic development for the Tees Valley Gateway initiative. AGHE were commissioned to undertake detailed electrical distribution surveys for both station and operational infrastructure and produced electrical, lighting and mechanical detailed designs for a new incoming power supplies for Network Rail and Northern, new access for all footbridge including three lifts, a new London Midland style footbridge (required as a secondary means of escape due to the stations new operational rating), waiting room, taxi office and car park. This scheme follows many other successful station and footbridge projects which include Beeston, Menton, Magna and Luton Airport Parkway.
Doncaster to Scunthorpe: LNE Signalling Power Distribution Renewals
This scheme oversaw the renewal, upgrade and installation of Principal Supply Points (PSP’s), Auxiliary Supply Points (ASP’s), Functional Supply Points (FSP’s) and lineside 650V electrical distribution cables and containment, from Scunthorpe to Doncaster. Building on the success of previous similar schemes including Birmingham New Street Re-signalling, Derby Area Remodelling, Port Talbot Area Re-signalling and London Victoria Re-signalling, AGHE produced detailed designs following detailed site surveys of Distribution and Plant assets. This scheme renewed legacy Class I signalling power distribution equipment for Class II solutions, using novel distribution solutions across a complex trackside project route, flanked by waterways, and river crossings requiring significant collaboration with Signalling and Civils design disciplines.
Shrewsbury Depot
Lighting
AGHE were commissioned to undertake surveys and detailed design for the installation of new lighting and electrical distribution to serve the refurbished depot for Transport of Wales. Due to the nature of the existing site and p-way layout, a bespoke lighting solution was designed and installed which provides strip lighting for driver’s walkways whilst also providing illuminance to the underside of train carriages to enable inspections by maintenance staff. The lighting controls were designed to be DALI controlled, incorporating a central battery system for emergency escape. This scheme follows many other successful sidings and depot schemes undertaken by AGHE including Holbeck Depot as part of the Transpennine Route Upgrade, North Pole, Bristol Stoke Gifford and Swansea Maliphant as part of the national Intercity Express Programme and Hull Botanic Gardens refurbishment.
