“…Several publications discuss demand side management for 50 or 60 Hz public power supply grids [1] [2]. Methods for the system design of railway power grid exist [3] [4], but focus on the average demand and not on the management of short -term fluctuations. The Swiss Federal Railways (SBB) operates an electric power supply grid that is separated from the public grid.…”

The analysis of the noise of a system is often an effective way for obtaining information about its internal dynamics. In this article, an analysis of the variance of the noise on the power load curve of the Swiss railway system guides us towards the detection of a multimodality in the distribution of punctualities. This multimodality is regarded as a strong indicator for a dynamics with multiple, possibly self-organized, regimes. The presence of multiple regimes in the dynamics is of relevance for the design of control strategies. Based on information about the operation of the Swiss regular interval time table, we suggest and apply a simple way for identifying the part of the load signal that can be regarded as noise and we demonstrate the use of Hartigan's dip test for the identification of multimodalities in the distribution of random variables.
