                 To  determine  the  load  of  the  electrification  system,  simulation  software  has  been  used  to
                 determine the power demanded or returned by each train at each time point and its position
                 according  to  the  parameters  that  influence  the  energy  consumption. After  determining  the
                 power and its position in the track of each train for each instant, and therefore the locations of
                 the loads in the electric circuit, the behavior of the electrification system has been determined.
                 Depending on the time step used in the simulator, the static or dynamic behavior of the system
                 can be analyzed.
                 Figure 12 gives a schematic supply layout for three substations. The neutral sections at each
                 substation are bridged with bypass switches, the ones between substations are in use.

                  By using converters in each substation, interconnection of all supply sections is possible. Figure
                 13 gives a schematic supply layout for three substations with converters. All neutral sections at
                 each substation and between all substations are bridged with bypass switches.
