Abstract
The number of reported errors on the catenary is relatively few in comparison with errors relating to the remaining parts of the railway system. This is an interesting fact, as errors linked to the catenary causes 30% of the total train delays. The substantial delay effect may be due to the many different companies participating in the railway business, and the several technical components correlating within the railway system. There are several factors affecting the error statistics. These can be among other things aging catenaries, lack of maintenance follow-up, poor communication between companies linked to the railway and varying weather conditions. In this thesis we try to determine how the various factors are interrelated and how... (More)
The number of reported errors on the catenary is relatively few in comparison with errors relating to the remaining parts of the railway system. This is an interesting fact, as errors linked to the catenary causes 30% of the total train delays. The substantial delay effect may be due to the many different companies participating in the railway business, and the several technical components correlating within the railway system. There are several factors affecting the error statistics. These can be among other things aging catenaries, lack of maintenance follow-up, poor communication between companies linked to the railway and varying weather conditions. In this thesis we try to determine how the various factors are interrelated and how they affect each other. The railway vehicles are constantly tied to the track. Therefore the system is vulnerable to disturbances. There are no "passing lanes" if errors occur, and delay effects will thus quickly reach extensive levels. The thesis highlights the importance of looking at the big picture to be able to identify the critical points of the system. This will in the long-term improve the reliability of the catenary system and the railway system as a whole. Critical points that require improvement, and which are covered and analysed in our thesis include: • Cooperation and communication
• Follow-up work
• Consideration of the existing legislation Keywords: catenary, pantograph, catenary damage, maintenance, train delay (Less)
