Course Content (Syllabus)
The “Railway Infrastructure” course covers all three components of a railway system: the track, the rolling stock and the exploitation.
It focuses on the interurban railway systems (high speed and conventional speed) and mainly on design and construction issues.
Its objective is to provide students with the necessary knowledge in order to comprehend the main principles in designing, constructing and operating railway systems but also to enable them to face the railway projects they will come across.
The course covers the following thematic items:
• The railway technique and potentials (the railway as a transport system; railway historical evolution)
• Railway traction ( traction elements , traction systems)
• Wheel – rail interaction (traffic loads, wheel-rail contact surface study, forces exerted on the track)
• Track panel (rails, sleepers, fastenings ,switches and crossings)
• Track bed layers (ballast layers , substructure, track bed / subgrade system)
• Track alignment (track alignment geometry, track defects)
• Track mechanical behavior (vertical behavior, lateral behavior)
• Civil engineering structures in railway systems (tunnels, bridges, etc)
• Track installations (signaling, electrification, level crossings)
• Rolling stock
• Rolling stock behavior on the track (axles/bogies behavior, vehicle’s derailment)
• High speed trains (Problems and solutions )
• Technical and commercial exploitation of railway systems
• Urban (metro, tramway) and interurban railway systems
• Track maintenance
• The railway systems in Greece
