A method for safely determining a position information of a train on a track includes an on-board system determining appearance characteristics, current distances relative to the train and current angular positions relative to the train of passive trackside structures with a first sensor arrangement of a first localization stage of the on-board system. The on-board system stores a map data base in which georeferenced locations and appearance characteristics of the passive trackside structures are registered. A first position information about the train is derived from a comparison of determined current distances and current angular positions and the registered locations of allocated passive trackside structures by the first localization stage. A second position information about the train is derived from satellite signals determined by a second sensor arrangement of a second localization stage. The first and second position information undergo a data fusion resulting in a consolidated position information.

Method for safely and autonomously determining the position information of a train on a track

Method for operating a network (), wherein the network () comprises at least one outer network () having at least one network device () and at least one inner network () having at least one network device (), wherein additionally a transmission unit () is present that blocks a transmission of data from the outer network () to the inner network () and allows it in the opposite direction (or vice versa), characterised in that the transmission unit () permits a transmission of data only from the inner network () to the outer network () and the at least one network device () sends data from the inner network () to the transmission unit () with a first address, wherein the transmission unit () converts this first address into a second address and thereafter the data are transmitted with this second address in the direction of the outer network (), the second address being a target address for the at least one network device in the outer network ().

A method for safe supervising train integrity includes: (a) acquiring first position data of the first carriage via a first tracking unit which is installed on-board of a first carriage and acquiring second position data of a second carriage via a second tracking unit which is installed on-board of the second carriage, wherein the position data is related to a rail route coordinate system; (b) determining a deviation between a reference value which depends on the length of the train and a position value which depends on position data of at least one of the tracking units; (c) detecting whether train integrity is given by analyzing the deviation; (d) repeating steps a) through c); wherein the tracking units are part of on-board units of an automatic train protection system. Thus a cost-efficient method for supervising train integrity which complies with safety level SIL4 can be realized.
