|
|
| |
|
|
|
Expected technological development: basically exploited |
| |
|
|
|
|
Simulation programmes offer minor optimisation potential by taking more parameters (track conditions, traffic situation etc) into account. |
|
|
|
|
| |
|
|
|
Motivation:
|
| |
|
|
|
|
Availability of reliable energy consumption data for billing and other purposes |
|
|
|
|
| |
|
|
|
Benefits (other than environmental): medium |
| |
|
|
|
|
Availability of energy consumption data for billing purposes (as long as no energy meters are deployed). |
|
|
|
|
| |
|
|
|
Barriers: low |
| |
|
|
|
|
Costs for IT and personnel are moderate since a database is a central instrument for the entire company. |

Database for traction energy consumption at DB AG
At German DB, a database for traction energy demand of rolling stock has been
developed. The content of the database is generated by simulations of train
runs. The database is used to calculate impacts of alternative alignments, new
vehicle conceptions or changed operation modes on the energy demand of all
related trains in order to facilitate an environmental and economic assessment
of such measures. |

|
|
Energy efficiency potential for single vehicle: not applicable |
| |
|
|
|
Energy efficiency potential throughout fleet: (no data) |
| |
|
|
|
|
A reliable database of the energy consumed by individual trains provides valuable information for decision making in vehicle, infrastructure and operation strategies.
The effect on actual energy consumption is difficult to quantify. |

|
|
|
|
| |
|
|
|
Infrastructure - running costs: unchanged |
| |
|
|
|
|
Operation costs of database are mainly for personnel and are low since only one database is required for the entire company. |

|
The development of a reliable database for traction energy demand can provide valuable information for decision-making processes in railways. Barriers and costs are low. Consumption data generated by simulation should be seen as a powerful instrument to predict the effect of different measures. Empirical consumption data from on-board measurements can be used to verify and refine simulations. |
