Energy is an integral quantity. This means that the cumulated energy is the decisive factor. Realistic train operation always takes place under the constraints of infrastructure and operational requirements. The following train modes are used in this standard: -In-service with commercial operation mode: This mode covers the normal operation of a train, including several passenger load cases or a locomotive hauling a consist of freight wagons. The train is moving or is stationary and the HVAC system is running in its normal operation mode. – In-service without commercial operation mode: In this mode a passenger train is stationary, the HVAC system is in operation as for commercial operation but without passengers in the train. This situation occurs frequently, for example when the train is waiting between two commercial runs. Parking mode: A train is in parking mode when it is stationary in depots, with the power supply active, without staff or passengers being on board. Usually, the HVAC system runs with reduced settings for temperature and airflow. Other train modes such as empty carriage stock movements are not considered in this standard as they do not contribute significantly to the annual energy consumption. In this standard the preconditioning (pre-heating or pre-cooling) and cleaning are not considered separately. The corresponding hours shall be counted in the in-service without commercial operation mode.This document incorporates infrastructure and operational conditions into “service profiles” for the train. The service profile for traction and auxiliaries is assessed via train runs along a line for in service with commercial operation and stationary at the depot for in service without commercial operation. HVAC is assessed via an operational point matrix for different operational modes. The energy consumption over such service profiles shall be used as an input when assessing LCC. This requires a well-defined and harmonized methodology for specification and verification of the energy consumption. The selected approach has two steps: a) simulation of the energy consumption of the train for the three energy categories mentioned above; b) verification of the simulation by undertaking measurements.BS EN 50591 pdf download.
