Data collection DPI
has won an important contract to help improve data collection on the
TfL’s Central line. It involves the supply of 200 embedded computers that will be installed on all Central line trains.
They will link into existing on-board acquisition systems, storing data locally and downloading to Central line wi-fi points strategically placed
along the line. This will enable TfL’s

Directorate to acquire data in a much timelier manner and spot developing issues before they become a bigger problem.
DPI believes it has won this contract for several reasons; fi rstly it was able to offer TfL a completely bespoke design service. This enabled TfL to get exactly what they needed for this project.
TfL had limited space and very specifi c connector requirements so as to minimise alterations to existing systems.

Increasing level crossing safety is an important objective of rail operators, argues DAC Ltd director Andrew Faulkner.
T
here are many dangers associated with level crossings, particularly when crossings are located in rural areas.
Hearing trains approaching can often be diffi cult for users of crossings for various reasons; windy weather, MP3 players, vehicle music and mobile telephones will all affect people’s ability to hear approaching trains.
Weather conditions such as snow, rain and fog may also affect the warning that a user receives that a train is on the way. In some places, bridges, buildings and embankments may restrict the view. All of these parameters, often coupled with user complacency, are potential dangers for a pedestrian, cyclist or driver who needs to cross a railway line.
Every year people are killed and injured in accidents at level crossings and the provision of a telephone would help to make them safer.
A number of factors have prevented rail 122 | rail technology magazine Apr/May 13
operators from providing a telephone terminal at these crossings; infrastructure restrictions, or diffi culties involving the provision of a telephone, for example no cable or power, coupled with the high cost of installing and maintaining assets in often remote locations.
Additionally, until re- cently the technol- ogy has not been readily available for manufac- turers to provide a solu- tion.
DAC Limited has developed a solution that could be the answer.
no problem
Trials of the RA708-GSM/GSM-R telephone are close to completion, and this standalone device can be located anywhere there is GSM or GSM-R coverage. No power, no cables, no infrastructure, no problem!
Installation is simple, and the telephone is designed to be user-friendly, mimicking existing telephones that are already widely used on crossings.
In addition, the RA708-GSM/GSM-R has a certain amount of on-board intelligence, providing internal health status checks to ensure serviceability levels are maintained, reporting via SMS, should there be a problem, before the problem turns into an incident.

company with experience in placing computers into the harsh underground networks, which DPI had.
DPI was also able to design a system capable of meeting TfL’s tough RIA12 standards.
DPI also worked closely with TfL during proof of concept and was quick to accommodate changes needed during the development phase. TfL also had demanding cost targets, which DPI managed to achieve.
DPI is currently working closely with TfL’s installation teams helping ensure all systems are installed correctly and working to TfL’s satisfaction.
