WAGON leasing company VTG Rail UK and braking equipment supplier Knorr-Bremse Rail Systems (UK), are carrying out a main line trial of nine wagons fitted with digital technology which they claim has the potential to revolutionise performance of rail freight.
VTG says the initial ‘iWagons’ feature 12 innovations including new wheelsets which feature four axle end generators to power patented Wheel Flat Prevention (WFP) technology, which monitors slide of wheelsets and condition of the brakes. The information can be accessed remotely, giving the ability to highlight issues as they occur and the potential to help Network Rail to locate areas where there is low rail adhesion. The ‘iWagons’ also feature axle lock detection.
“Our patented Wheel Flat Prevention technology increases wheel life and reduces potential deep wheel flats which may result in track damage, or in worst cases, derailment,” commented Knorr-Bremse engineering and innovation director Sanjay Albert, adding that digital monitoring would offer insights to customers and the wider industry to enable more efficient maintenance and operation.
Future trials
In future trials, it is anticipated that the axle end generators will provide the energy for equipment to gather further real-time data for maintenance and identify wagon and bogie imbalances. VTG says the on board technology is capable of offering further advantages when used in conjunction with its ‘i-Maintenance’ data platform (which can predict wheelset damage) and the VTG Connect information system.
