Rail network

Rail network

A rail network is the necessary infrastructure for trains, metro or tram. The track consists of two parallel steel rails, anchored perpendicular to members called ties (sleepers) of timber, concrete, steel, or plastic to maintain a consistent distance apart, or rail gauge [ref wikipedia]. Turnouts, also known as points and switches, are the means of directing a train onto a diverging section of track [1]. Signalling is used to control the direction of the switch and to prevent collisions.

The rail network can be used both for passenger and freight transport.

Vulnerable or unsafe parts of a railway network are level crossings with other infrastructure, switches, steep curves (risk of run off the rails) and stations.
