UK-based transport operator Go-Ahead Group has awarded two contracts to Knorr-Bremse to install driver advisory systems on the diesel train fleets operated by London Midland and Southern.
Under the deal, Knorr-Bremse will install its Leader Driver Advisory System (DAS) on 16 Class 171 DMU trains operated by Southern, and 23 Class 170 DMU and 27 Class 172 DMU trains operated by London Midland.
The DAS system will be equipped inside the driver’s cab of the locomotives to help drivers ensure optimum performance against the timetable.
Knorr-Bremse’s DAS is a computerised system that uses real-time information about the train’s dynamics, the timetable and the route profile, including specific topography and speed limits.
The system calculates the best speed in the prevailing circumstances for a train route, helping drivers to change their own driving style to optimise journeys.
The Leader DAS also helps cut locomotive energy usage and carbon emissions through reduced fuel consumption.
Go-Ahead Group engineering director Phil Margrave said that during trials, the Leader system demonstrated energy savings on various routes.
"The installation of the system supports our commitment to seek new ways to cut our environmental impacts and work towards our target of reducing our CO2 emissions per passenger journey by 20% by 2015," Margrave said.
Knorr-Bremse UK managing director Paul Goodhand said that the contacts comprise the supply of all necessary in-vehicle equipment including the main Leader DAS and all back-office support for the remainder of the two franchises.
"We will also provide back up for the system while it is in service," Goodhand said.
Knorr-Bremse is expected to complete the installation and commissioning of the Leader systems on both fleets by Autumn 2013.
Go-Ahead Group has a joint venture partnership with Keolis called Govia, which operates the London Midland, Southeastern and Southern rail franchises.
