InterCity (commonly abbreviated IC on timetables and tickets) is the classification applied to certain long-distance passenger train services in Europe. Such trains (in contrast to regional, local, or commuter trains) generally call at major stations only.
The Inter-City Rapid Transit Company was an Ohio interurban company, which began operations in 1930 as it had purchased its route from the Northern Ohio Traction & Light Company. It remained in operation till 1940.
The use of Inter-City was reborn in the United Kingdom: A daily train of that name was introduced in 1950, running between the cities of London and Birmingham. This usage can claim to be the origin of all later usages worldwide.
In 1966 British Rail introduced the brand InterCity for all of its express train routes, and in 1986 the term was adopted by the InterCity sector of British Rail. Following the privatisation of the railways in Great Britain the term is no longer in official use there, although many people still refer to fast long-distance services as InterCity trains. The brand still exists though, and according to DfT is owned by them.
In West Germany, the Deutsche Bundesbahn first used the name (then written Intercity) in 1968, denoting special first-class services on the F-Zug train network. Many of the Class VT 11.5 diesel multiple units formerly used on the TEE network were converted for early Intercity services.
In Switzerland, the InterCity brand replaced SwissExpress in the 1982 schedule.
In Norway, intercity (later also written InterCity) trains were introduced in 1975 on the Vestfold Line (the Oslo-Skien service), later also on the Østfold Line (Oslo-Halden). They were (relatively) fast trains on distances up to 2–3 hours. Today, the name is used not on the trains, but on the main lines from Oslo to Skien, Lillehammer, and Halden – and also on the Ringerike Line, which is under construction from Oslo to Hønefoss.
