In today's field of railway, a number of stand alone inspection systems are available and each of them addresses only particular train fault-states. Our work describes a concept for integration of these systems into a complete "checkpoint" system with regard to the specific application range of railway vehicle inspection 1 . In contrast to single fault-state detection systems, our concept of an overall system allows to combine sensor information and to evaluate train fault-states from a more global view. Hence, it provides an abstract data representation for establishing a common data base. To achieve enhanced information combining sensor data of asynchronously working sensor systems, a tight association between measurements and their particular measurement ranges on the train is an elementary functionality. As a crucial aspect, the accuracy of train fault estimation can be proved by the system. Furthermore, the ability of the overall system in characterizing fault-states will mostly be extended.

Ein ,,Checkpoint-System'' dient einer automatischen Zugü berwachung. Es wird an festgelegten Positionen einer Bahnstrecke montiert und bewertet Fehlzustä nde vorbeifahrender Zü ge, basierend auf den Daten verschiedenster Sensorsysteme. Im Rahmen von Forschungsprojekten wurde ein derartiges System entworfen und zur Ü berprü fung aufgebaut. Wä hrend fü r einige Fehlzustä nde marktreife Sensorsysteme vorliegen, mussten zur Branderkennung und Entgleisungsdetektion eigene Lö sungskonzepte entworfen werden.Schlü sselwö rter: automatische Zugü berwachung; Checkpoint; Sensorsysteme; Entgleisungsdetektion; Branderkennung Automatic train inspection by Checkpoint-Systems.A ''Checkpoint-System'' is designed for automatic train inspection. Localized at fixed track-side positions, different error conditions of passing trains are evaluated by data of specific sensor systems. Supported by research projects, a Checkpoint-System was developed and set up for performance analysis. Some types of error conditions are analyzed by commercially available sensors. However, own concepts for the detection of railway car fire and derailment had to be worked out.

Ensuring an uninterrupted supply of power in the electric traction is vital for the safety of this important transport system. For this purpose, monitoring and diagnostics of the technical condition of the vehicle’s power supply elements are becoming increasingly common. This paper presents a new visual method for detecting contact strip damage, based on measurement and analysis of the movement of the overhead contact line (OCL) wire. A measurement system configuration with a 2D camera was proposed. The experimental method has shown that contact strips damage can be detected by transverse displacement signal analysis. It has been proven that the velocity signal numerically established on that basis has a comparable level in the case of identical damage, regardless of its location on the surface of the contact strip. The proposed method belongs to the group of contact-less measurements, so it does not require interference with the structure of the catenary network nor the mounting of sensors in its vicinity. Measurement of displacements of the contact wire in 2D space makes it possible to combine the functions of existing diagnostic stands assessing the correctness of the mean contact force control adjustment of the current collector with the elements of the contact strip diagnostics, which involves detecting their damage which may result in overhead contact line rupture.
