This document provides an overview of various modules and concepts related to rail transport. It discusses topics like modal split, classification of railway systems, the components that make up railway infrastructure like the substructure and superstructure. It also examines the three pillars of the rail system: infrastructure, traffic, and trains. Other concepts covered include terminals and stops, guided transport systems, track alignment, turnouts and crossings, signalling and safety, and rail system design and capacity.

Site preparation.
Substructure
It comprises the subgrade itself, including in particular embankments, cuttings, drainage channels,
planting for protection side slopes etc.
Superstructure
This consists of the rails (including turnouts and crossings), sleepers, fastenings, ballast and sub ballast or slab track.
Engineering structures
Viaducts, (moveable) bridges, tunnels, covered cuttings, culverts and other underpasses, retaining walls etc.
Level crossings
Including appliances to ensure the safety of road traffic.
Traction power supply
Which includes catenaries or supports of third rail, substations, power supply cables and control equipment.
Safety, signalling and telecommunications installations
Signal masts and / or cab signalling systems, train detection system, train control equipment, cables and control systems.
Additional facilities
For example baffle boards, fences etc.
Ground area
Stations and stops
Terminals, platforms, pedestrian route, elevators, escalators, stairs etc.
