History

Construction (1969-1982)

The construction of Vienna's modern urban railway network started on 3 November 1969. This consisted of the newly built U1 line, and two merged lines from a tram and old metro, of the line U2 and U4 respectively. As the result of a more streamlined network, there were new routes between U1, U2 and U4.

The construction was launched in Karlsplatz, the largest interchange station in Vienna. On 25 February 1978, the first Vienna U-Bahn route between Karlsplatz and Reumannplatz, the U1, went into operation. By December 1981, all the sections of U1 originally included in the basic network (Reumannplatz - Stephansplatz - Praterstern, 6.1 kilometres in length) were into operation.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “U1 (Vienna U-Bahn)”, the useful work is to connect “metro line in Vienna” to the records capable of establishing context and consequence.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 30, 2026. The linked authority identifier is Q663755. The first chronological checks are 1978, 2017, 1969 and 1982.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
