![Stefan Fassbinder, Deutsches Kupferinstitut, Düsseldorf / European Copper Institute, Brussels www.kupferinstitut.de www.leonardo-energy.org http://leonardo-web.org/de Is railway transportation really energy efficient?And could it still be further improved? Two times yes!While everybody speaks about the electric car, the real potential lies on the rail! This diesel-hydraulic regional train consumes 1.7 litres of diesel fuel per km Fuel cost: 0.9 cents per km and seat! This electric long-distance train consumes17 kWh of electricity per km Electricity cost: 0.2 cents per km and seat This diesel-electric express train causes 1,800 € of fuel cost for one single trip from Berlin to Copenhagen, so some 15 to 50 seats (out of 195) have to be occupied alone for recovering the fuel cost! A car uses 100% of its engine power to run at maximum speed A train uses 33% of its locomotive power to run at maximum speed A car accelerates faster than a train? Well, initially yes, but somewhat later on... A car rolls 3.5 km disengaged A train has not even lost half of its speed after 32 km! Force and power of a locomotive – availability and requirement for running at constant speed in a flat area What to do about it? There are three action areas: Add new battery electric vehicles for poorly frequented lines where electrification does not pay off! ,[object Object]](https://image.slidesharecdn.com/railwayefficiencyposter-101020113955-phpapp01/85/Railway-efficiency-poster-1-320.jpg)

- 2. A suitable battery adds 50% to the price of a car but only 15% to the price of a train
- 3. Including the battery costs in the electricity price would triple the electricity price
- 4. Yet, the energy cost would still be lower compared to a diesel railcar!
- 6. A diesel engine in a railway vehicle spends >90% of its operating time idling
- 7. The nature of a diesel engine is pretty well suited for driving a car
- 8. The nature of a diesel engine matches the physics of a railway vehicle quite poorly
- 11. Improve brake management 20% -> 50%
- 12. Replace locomotive hauled trains with railcars (dispersed drives) -> >50%www.slideshare.net/LeonardoENERGYDeutschland/how-energy-efficient-really-is-railway-transportation
