Toshiba Railway Europe unveiled a electric-diesel-battery hybrid traction technology demonstrator locomotive at the Transport Logistic trade show in München on June 4.
The company has a contract to supply 50 diesel-battery centre cab locomotives to DB Cargo from 2021, TRE Managing Director Hinrich Krey told Railway Gazette. The demonstrator is intended to showcase the company’s design work to date as well as highlighting future development options.
The T-HDB800 displayed in München reuses the frame and bogies from a Schalke SDE1800 heavy industrial shunter. Diesel traction is provided by two MAN 471 kW gensets, while Toshiba has fitted two SCiB lithium titanate oxide traction batteries rated at 62 kWh. TRE says that the diesel engines use neither urea additives nor particulate filters, but will be compliant with EU Stage V emissions regulations coming into effect from 2023.
The powerpacks use a modular design which means that one could be replaced by another battery pack or ‘maybe fuel cells further in the future’. TRE says that simulations have suggested the batteries could last up to 10 years.
