This book contains the 14th proceedings of the, very successful, International conference on Railway Engineering Design and Optimization (COMPRAIL 2014), which began in 1987. Encouraging the update and use of advanced systems, the book promotes their general awareness throughout the business management, design, manufacture and operation of railways and other emerging passenger, freight and transit systems. It particularly emphasises the use of computer systems in advanced railway engineering. Topics covered include: Train Control Systems; Communications and Signalling; Computer Techniques and Simulations; Monitoring and Maintenance; Operations Quality; Planning; Timetable Planning; Rescheduling; Energy Supply and Consumption; Safety; Railway Vehicle Dynamics.
