3.1
rail system
rail network, related rolling stock, and the associated operation
Note 1 to entry: Operation means the procedures and logistics permitting the operation of the rail system.
Note 2 to entry: Rail networks may have sections of rack railway without being regarded as another or separate rail network.
3.1.1
conventional rail system
rail system in which rolling stock is supported and guided by steel wheels on two steel rails, located beneath the rolling stock, regardless of their design speed and track gauge
Note 1 to entry: The term “traditional” or “classic” rail system is also used.
Note 2 to entry: The term ‘conventional’ had a different meaning before the integration of the relevant ‘Technical Specifications on Interoperability’ (TSI). The meaning is not followed in this standard.
3.1.2
unconventional rail system
rail system in which rolling stock is supported and guided by means other than steel wheels on two steel rails, located beneath the rolling stock
EXAMPLES Monorail systems, magnetic levitation (MAGLEVJ systems, hanging systems, rubber tyred systems.
3.1.3
heavy rail system
conventional rail system intended for intraand inter-regional and/or international transportation
Note 1 to entry: The heavy rail system comprises the heavy rail network, related rolling stock and the associated operation.
Note 2 to entry: Typically, a heavy rail system has standard or broad gauge tracks and infrastructure which are designed for an axle load of at least 17 t. The vehicles comply with a structural design category L, P-I, P-Il or F-I according to EN 12663-1:2010+A1:2014 and a crashworthiness design category C-I according to
EN 15227:2008÷A1:2010.
Note 3 to entry: The heavy rail system is typically intended for passenger and freight transport.
3.1.4.1
metro system
urban rail system operated by using a command / control system segregated from road traffic or any other rail system
Note 1 to entry: The metro system comprises the metro network, related rolling stock, and the associated operation.
Note 2 to entry: Typically, a metro system has tracks and infrastructure, which are designed for an axle load less than 17 t. The vehicles comply with a structural design category P-li! according to EN 12663-1:2010+A1:2014 and a crashworthiness design category C-I! according
to EN 15227:2008+A1:2010.
Note 3 to entry: The metro system may include underground, elevated or surface sections.
Note 4 to entry: Exceptionally, metro systems may have level crossings and/or share tracks with other rail systems.
3.1.4.2
tram system
urban rail system operated on separate infrastructure or infrastructure shared with road traffic, or both
Note 1 to entry: The tram system comprises the tram network, related rolling stock, and the associated operation.
Note 2 to entry: Typically, a tram system has tracks and infrastructure, which are designed for an axle load less than 13 t. The vehicles comply with a structural design category P-IV or P-V according to EN 12663-1:2010+A1:2014 and a crashworthiness design category C-IV according
to EN 15227:2008+A1:2010.
Note 3 to entry: Sections of the route may be signal controlled.
Note 4 to entry: A tram network can be linked to other rail networks.
Note 5 to entry: For tram systems having sections segregated from road traffic the term light rail system (LRS) may be used.
Note 6 to entry: Road traffic includes road users like cars, pedestrians, cyclists, wheelchair users, etc.
