Axle Counter – Past Challenges 2 THALES u World-Wide market leader in Axle Counter Technology u More than 80 years experience with Axle Counters Title of presentation:

Axle Counter – Past Challenges 3 System Evolution u Introduction in the 1930 ies: First Inductive Rail Contacts BUT: Axle Counters not as reliable as Track Circuits u Change in the late 1960 ies: Introduction of Electronic Axle Counters -> Drastic Improvement of reliability compared to Track Circuits u New Generation in the 1980 ies: Introduction of Microprocessor technology -> Introduction of redundant system concepts (2 oo 3) and fault tolerant data transmission u 1995: German Railways DB decides to go exclusively with Axle Counters for Train Detection for two reasons u £ Economical: Application of Axle Counter much cheaper than Track Circuits £ Operational: Much higher reliability than track circuits 2000: Introduction of CENELEC Compliant Systems £ Modular and Scalable Thales Multi-Section Axle Counter Az.

Axle Counter – Future Challenges 4 What has in the past prevented the widespread application of Axle Counters ? Title of presentation:

Axle Counter – Past Challenges 5 Broken Rail Detection u Track Circuits can detect broken rails, Axle Counters can not…. BUT: u Can Track Circuits really detect Broken Rails (reliably) ? u Example: Statistic by MTRC (Hong Kong), June 27 th, 2001 SUMMARY: u Only independent Track Inspection (e. g. Ultrasonic) can reliably detect cracked and broken rail u -> Track Circuits can NOT ! Title of presentation:

Axle Counter – Past Challenges 6 Track Circuit Clips u A Track Circuit Clip can block a Track Circuit, e. g. in case of an accident, Axle Counter can not…. BUT: u What happens in block lines without train detection ? u Stopping a train to block an adjacent track is a safety risk by itself SOLUTION: u Train Radio is now widely available for driver communication u It is faster and safer than a Track Circuit Clip Title of presentation:

Axle Counter – Performance Challenges 7 How are Axle Counters today contributing to Railways growth in safety and operational efficiency ? Title of presentation:

Axle Counter – Performance Challenges 8 Full Redundant Axle Counter Applications u Train detection reaching 100% Availability ! Background: u Applications: Lines with extremely high train density, Operational Bottleneck sections, Difficult site access in case of failure (e. g. tunnels) u Areas with high impact on railway operation u -> Driven by financial compensation for Non-Availability (delay Minutes) Reference Projects: u Lötschberg Tunnel Project, Switzerland u HSL South High speed Line, Netherlands u Gotthard Tunnel Project Title of presentation:
