Status of development: test series |
| |
|
|
|
|
Test series (Europe) to marketable (Japan). Bogie fairings have been used in the Japanese Shinkansen 500 series (JR West) since 1997. In Europe a joint research project of DB, SNCF and FS, with the co-operation of the train manufacturer AnsaldoBreda, has been performed on the new multi-voltage ETR 500 high speed train. |

Time horizon for broad application: 5 - 10 years |

|
|
|
Expected technological development: dynamic |
| |
|
|
|
|
Compared to retrofitting measures on existing trains (as in the ETR 500 test series), bogie fairings for newly designed trains may be even more effective (according to optimistic assumptions, air drag may be reduced by up to 20% as compared to 10% for retrofit measures). |
|
|
|
|
| |
|
|
|
Motivation:
|
| |
|
|
|
|
- Noise reduction
- Energy efficiency (Future high speed trains with increased speed will
generate a strong rise in the energy costs of operations through increased air
drag.)
|
|
|
|
|
| |
|
|
|
Benefits (other than environmental): small |
| |
|
|
|
|
Wear of bogies is reduced due to better protection against damage by stones from track. |
|
|
|
|
| |
|
|
|
Barriers: low |
| |
|
|
|
|
Maintenance For maintenance purposes an easy access to the bogies is required. Bogie fairings obviously make access more difficult, but this problem can be minimised by intelligent construction. |
|
|
|
|
| |
|
|
|
Success factors:
|
| |
|
|
|
|
Assess possibility of integrating bogie fairings into specification sheets of new high speed stock. |
|
|
|
|
| |
|
|
|
Applicability for railway segments: medium |
| |
|
|
|
Type of traction: electric - DC, electric - AC, diesel
|
| |
|
|
|
Type of transportation: passenger - main lines, passenger - high speed
|
| |
|
|
|
|
Bogie fairings are mainly discussed for high-speed trains, where air drag is dominant. |

|
Grade of diffusion into railway markets:
|
| |
|
|
|
Diffusion into relevant segment of fleet: < 5% |
| |
|
|
|
Share of newly purchased stock: < 20% |
| |
|
|
|
|
No in-service use in Europe. |
