Control of comfort functions in parked trains |
 |

 |
|
|
| Parked passenger trains are often heated all night. This consumes substantial amounts of energy. A possible solution is the development and implementation of an intelligent control tool for parked trains.

According to different sources, in countries of Central and Northern Europe energy consumption during standstill is up to 10% of the total energy demand for train operation. In Mediterranean countries, the share will be lower.
It is a reasonable estimate to assume that this energy can be reduced by ~ 50% by an intelligent control system. So the saving potential is about 2 - 5 % per vehicle.
This estimate may be even rather conservative compared to calculations made by SJ in the context of their introduction of the PLC system. The operator estimated a saving potential of 15.000 kWh per year and coach. Given the total consumption for coach heating of about 55.000 kWh per year and coach, the measure is expected to save between 20 and 30% of the energy consumed for heating. Since heating energy (including both during standstill and operation) makes up about 20-30% of the total energy consumption of a train, the saving potential of the measure (with respect to the vehicle’s total energy consumption) is therefore between 4 and 9 % per vehicle. This is realistic in Scandinavian countries but would be too optimistic for countries like France or Italy. |
