Toshiba Unveils Tri-Mode Locomotive Demonstrator
The title of this post is the same as that of this article on Railway Gazette.
This is the first two paragraphs.
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.
It is based on the frame and bogies of a heavy shunting locomotive.
- There are two MAN 471 kW gensets.
- The diesel engines are compatible with EU Stage V emissions regulations.
- There are two SCiB 62 kWh lithium titanate oxide traction batteries.
- Battery life is quoted as up to ten years.
- The design is modular, so that a diesel engine can be replaced with another battery pack.
- A pantograph working with common European voltages can provide electric power.
The locomotive is aimed at heavy shunting and light freight.
Conclusion
The power of the locomotive is probably about 1MW, which is less than half the power of a Class 66 locomotive. But locomotives like the Class 66 are often used for tasks, where a smaller locomotive could do an excellent job.
The low pollution of the Toshiba locomotive probably means it could work in sensitive areas or close to a workforce.
The locomotive appears to be a well-designed locomotive for an important niche market.
If this design and others like the Stadler Class 93 locomotive succeed it will lead nearer to the ultimate goal of a high performance heavy freight zero-carbon locomotive to replace the polluting diesel locomotives, that are so common on the railways of the world.
