Improving track and ride quality on the nation’s rail network
John Vaines, managing director of Diamond Point International (Europe) Ltd, discusses ride quality. W
hile Network Rail is facing a reported £70m fine from the Office of Rail Regulation (ORR) for underperforming to timetable, Diamond Point International (DPI) and Infrastructure Measurement Solutions (IMS) have been busy designing a cost-effective system to record track derived issues
that result in unacceptable ride quality.
This is known to have a knock-on effect on meeting timetable goals.
The ‘Bump box’, as it has been affectionately called, has been designed to be cost-effective enough to be considered for use on all trains currently running, allowing Network Rail and its partners to develop a
The system can be set to monitor and record pre- defined shock levels and record pre- and post-event data, along with time and GPS co-ordinates. This data is stored locally in a graphical and numerical form. It can be transmitted via wi-fi to a rail engineer’s laptop or sent via 3G-encrypted GPRS to a cloud-based repository where individual users
much more complete picture of developing issues within the UK rail network.
Network Rail is currently evaluating the system with some train operators. Initial feedback is very positive, as more units are being ordered.
can look at their results through a secure log-in
system.The next biggest issue to overcome is how you manage the stored data. DPI and IMS have created a software package that can be tailored to the individual TOC’s/rail operator’s needs, providing varying levels of information dependant on the enquirer’s login status. This data can also be used in trending algorithms to help improve an operator’s ability to predict when maintenance is required and to prevent unacceptable levels of shock and vibration, helping to prevent total failure.
