Reference Projects
The KeTech Group have many years experience in providing communication system solutions across vertical market sectors. This section includes a number of reference projects which demonstrate KeTech's broad range of experience and expertise and highlight the many resources available to customers from within the KeTech Group.
Chiltern Railways – CIS, CCTV and Clocks
Customer: Chiltern Railways
This real time Customer Information System (CIS) comprises of a single Central Server that communicates, via a WAN, to Local Controllers at each of the 30 plus stations, each of which have a configurable number of CIS displays.
The Central Server, located at Marylebone, contains all information relating to timetables, routes, departure schedules etc. for Chiltern Railways and provides the interface to real-time train running information.
The existing CCTV system was extended to provide coverage at an additional 10+ stations, with remote monitoring capability and local analogue / digital recording.
Northern Rail - Customer Information System (CIS)
Customer: Northern Rail
This Customer Information System comprises of a Central Server that communicates via a WAN to Local Controllers at each station, each of which have a configurable number of passenger displays. These communicate via a Local Area Network.
The system has been installed at the following locations:
a) Meadowhall
b) Rotherham
c) Swinton
d) Barnsley
Sunderland Station – CIS, PAVA, CCTV
Customer: Team Telecom (on behalf of Sunderland Direct)
This CIS system uses a Central Server to drive a network of public display devices. The display devices are a mix of CRT devices driven over the system LAN via a local intelligent display controller built into the display device or a LCD sign driven directly from the central server.
The equipment is linked either via a LAN or asynchronous links over a fibre cable network. The Central Server incorporates an additional interface to the PAVA system to provide auto-announcement facilities based on the integrated timetable.
The CCTV system provides a 31 day digital recording facility for the 30 plus cameras located around the station platforms and concourse.
All systems have been designed to meet the requirements of a section 12 underground station.
Sunderland - DOO CCTV System
Customer: Team Telecom (on behalf of Sunderland Direct)
Whilst the traditional approach adopted by Network Rail had always been to use portrait mounted CRT units for the display of CCTV images, space constraints prevented this at Sunderland. As a result, KeTech Systems designed a system using TFT LCD’s, obtained Network Rail approval and then installed and commissioned the new system.
It should be noted that as a result of demonstrations of this innovative solution at Sunderland, and comparison with the conventional CRT approach, LCD TFT displays have now become Network Rail’s preferred solution for DOO.
All equipment has been designed to meet the requirements of a section 12 underground station.

LUL - Maintenance of BTP LLCCTV System
Customer: LUL
KeTech Systems was awarded the contract to support and maintain (24/7) the BTP LLCCTV System, which enables remote access to the stations CCTV system. KeTech Systems has been responsible for the maintenance of the BTP/NCC system (including the full control room telemetry system) since 2000.
During this period we have acquired significant expertise in all elements of the system including the British Relay Mk13 system and the current PSH96B modem configuration, which extends to the repair of obsolete equipment.
LUL - BTP LLCCTV Control & Management System
Customer: LUL/British Transport Police
KeTech Systems provided the replacement Control and Management System and has developed new 3D axonometric plans for each station showing the location of cameras (selectable via the icons), together with other items of importance such as barriers, Help Points etc. This replaced the existing line drawings.
Piccadilly Line - Passenger Information System Auto-upgrade
Customer: LUL/Tube Lines
The existing Passenger Information System (PIS), which was originally designed and supplied by KeTech Systems in the mid 1990’s, used internal LED and front of Train LCD displays, together with audio auto-announcements.
This contract included an upgrade of the audio-visual on-board Passenger Information System (PIS) on the Piccadilly Line rolling stock.
The new system calculates the position of the train through the use of the WSP (i.e. speedometer) and door signals, coupled with details of the Underground network. The upgrade also allows announcements to be modified depending on the position of the train i.e. ‘the next station is…’ and other messages to be broadcast in the event of an unscheduled occurrence.

With the relocation of the National Blood Transfusion services from Southmead Hospital to new purpose built premises, 2As' installed Trend IQ3 web enabled controllers to provide main HVAC plant control at the new facility.
Southern Rail
Over 150 stations controlled from a central control room at Streatham Hill over an ethernet network. The system provides Automated Digital Voice Announcing (DVA), local announcing for station staff and Long Line Public Address (LLPA) via ISDN telephone from the control centre. Note that the LLPA facility has recently been updated to work over Voice over Internet Protocol (VoIP), providing a significant saving to the client in line rental and call charges. The PA systems ranged in size from a single amplifier station, to East Croydon which required 12 amplifiers and 4 simultaneous DVA channels.
First Great Western
Ditra Systems provided a full Public Address Voice Alarm (PA\VA) system for 20 stations on the FGW network. Facilities included automated DVA (up to 4 channels), LLPA via ISDN and multiple local microphone interfaces. Ambient Noise Sensing (ANS) adjusts the announcing levels in relation to the background noise.
