Single-axle running gear are a very promising concept for replacing heavy 2-axle bogies in mid-term perspective. Energy efficiency effects are especially high in local and regional transport. In this railway segment, the Alstom KERFs represent a mature technology with first experience from regular service. Future developments and refinements point in the direction of mechatronic control. In long term perspective, a complete technological migration from conventional running gear to single-axle concepts in local and regional passenger transport should be aimed at. |
