Issue 7 | Evaluating rolling stock
Vehicle design is one of the most decisive determinants for the energy consumption of passenger railway operations. When procuring rolling stock, the PTA should ask for the vehicles' energy consumption data, which should be understood as a quality feature of the vehicle class.
When the TOC is to provide the rolling stock it is recommended that the PTA asks for data about the energy consumption of the vehicles to be used. These should be evaluated separately from the operational performance, which is also influenced by other factors. The methodology is the same as when procuring rolling stock.
The approach that is presented in the Guidelines includes the definition of maximum and/or reference levels, the definition of service profiles and options for verification.
When procuring loco-hauled carriages, the weight per seat ratio is relevant.
