Virtual reality simulations showed the hybrid technology could reduce CO2 emissions along the Lake Constance Belt Railway in southern Germany by up to 20% compared to the route’s existing diesel trains.
The MTU Hybrid PowerPack has been developed for non-electrified railways that still depend on the polluting fuel source.
Lars Kräft, Vice President Industrial Business at Rolls-Royce Power Systems said: “With the Hybrid PowerPack, we are offering an environmentally-friendly rail drive solution that combines the benefits of battery and diesel-driven trains.
“Trains fitted with our hybrid drive system could improve operations on the Lake Constance Belt Railway within just a few years – with considerably less noise, fewer emissions and more connections with more stops – and this can be done with no additional infrastructure costs.“
Rolls-Royce Power Systems, which is headquartered nearby, is working on a range of new hybridisation technologies for trains, yachts and power generators which are due to go into production in the near future.
