Engine off - efficiency on


Stop-start system for locomotives

    Making freight transport by rail more efficient – that is our goal. The question of how we achieve this together with you is what moves us.

    The locomotive's traction diesel engine is a crucial starting point. Loading and unloading as well as line bottlenecks result in long waiting times every day in rail freight transport. As a consequence, locomotives are operated at idle for more than 30% of their service life. This is where the automatic stop-start system OnEfficiency.StopStart comes in. By switching off the engine during waiting times, high operational savings are possible. Thanks to simultaneous monitoring of the auxiliary operations by our system, nothing stands in the way of continuing the journey. Together with us, take the decisive step towards efficient rail freight transport. Our experts can handle the full support on your behalf – from design to certification.

    Our G1206 shunting locomotives have a high idle share that cannot be further reduced operationally. For both economic and ecological reasons, we have therefore decided to equip our fleet with OnEfficiency.StopStart.

    Red signal light indicates that the block section ahead is occupied and the train must stop.
    The stop-start technology reduces the idle time of the engine by 720 hours per year on average.
    On average, 30,000 kg of CO2 can be saved per locomotive in one year.
    An average of 20,000 € can be saved per locomotive each year thanks to reduced fuel and maintenance costs.
    An average of up to 11,000 liters of fuel saved per engine every year results in lower fuel costs and fewer refueling stops.
