Modular energy concept for last mile operation in single-wagon freight transport

Abstract

The objective of this paper is to investigate the feasibility of integrating interchangeable power supply modules for self-propelled single wagons. For this purpose, 27 last mile operation are identified by collecting track data from sidings to the nearest marshalling yards, clustered in terms of length, elevation and speed. On this basis, the energy demands for each scenario is simulated to design a modular energy concept, with the focus to interchangeable modules in a flexible packaging concept. The investigations presented in the paper show that a modular energy storage concept for single-wagon transport is feasible to fulfil the diversity of requirements for the identified last mile operation scenarios. The developed concept is presented in a 1:25 demonstrator including a graphical user interface.
