Other rail

Diverse range of rail systems not classified as heavy rail, primarily for short-distance passenger transport and generally functionally separated from heavy rail networks. Includes: - urban and suburban transport systems: metro lines (see A.I-18), tram lines (see A.I-19) and other urban light rail lines (see A.I-20); - dedicated networks: funicular (see A.I-22) and rack (see A.I-23) railway lines, often used in mountainous regions or for steep gradients; - touristic rail lines (see A.I-21): rail systems designed for leisure or sightseeing, such as heritage trains. Tram-train systems (operating primarily on light railway networks, but also on heavy railway networks) are classified under ‘Other rail’. Train-tram systems (mainly operating on heavy railway networks) are classified under ‘Heavy rail’.
