Coupling of parked trains for common energy supply |
 |
evaluated |
 |
|
|
| Connecting parked trains electrically to facilitate a common energy supply improves the efficiency of heating and lighting during overnight standstill periods in those passenger trains which cannot be easily connected to the regular stationary grid.

Impacts on energy efficiency:

Energy efficiency potential for single vehicle: < 2% |

|
Energy efficiency potential throughout fleet: < 1% |

The stand-still energy consumption of two trains coupled together can be reduced by 25%. However, the measure saves energy only if two train sets happen to stand together in the stand-still areas and can be coupled. According to DSB, this holds for about 50% of the cases. Given that overnight heating accounts for 5-10 % of total energy demand of passenger train operation, the measure has an average saving potential per vehicle of about 1 %. |
