s in the central city area.

Stadtbahnen were mostly implemented in the 1960s and 1970s with the long-term goal of establishing a full-scale metro system, but by the 1980s virtually all cities had abandoned these plans due to the excessive costs associated with converting the tramways. Most Stadtbahn systems are now a mixture of tramway-like operations in suburban and peripheral areas and a more metro-like mode of operation in city centres, with underground stations.

1960s: West Germany's 'pre-metro' projects

Since the 1960s the term "Stadtbahn" has become identified with a second, and now dominant, meaning.

Post-World War II transport policies in West German cities aimed for a separation of public and private transport. The conflicts that arose between increasing car usage and the existing tramway systems led to the so-called 'second level' concept for future light rail schemes. This concept focused on the grade separation, i.e., elevation and/or tunneling of tram lines.

 planned expansions of their existing U-Bahn networks, while most West German cities decided to upgrade their tramway networks step by step, linking new 'second level' infrastructure to existing sections. While some cities regarded this solution as an interim step that would lead to a fully separated U-Bahn (metro) network independent of other forms of transport, others planned for a lesser degree of separation, one that would accommodate additional tram-like sections in the long run. For both the interim and the long-term based concepts, the following terms came into use: "U-Straßenbahn" or "Untergrund-Straßenbahn" (underground tramway, abbreviated as "U-Strab") , "Schnellstraßenbahn" (rapid tramway) and finally "Stadtbahn". (In French-speaking countries, these concepts were also known as "pre-metro

1980s: Renaissance of the tramway

By the 1980s conventional tramways had been seen by decision-makers as overloaded systems for almost two decades. However, public attention focused on them at this time for two reasons.

The Stadtbahn cities' second level plans faced unexpected complications in the form of lengthy construction work, budgetary problems for tunnel projects, and protests against elevated sections. At the same time, the smaller cities which had not started Stadtbahn plans reassessed their options in relation to their existing tram systems.

The "Stadtbahn" term has now come to have the vague meaning of 'modern tramway' or 'modernized tramway'. It has become impossible to differentiate between Straßenbahn (trams) and Stadtbahn (light rail).

Among the first cities to use the "Stadtbahn" term to mean their upgraded tramway systems with no link to appreciable second level infrastructure were Würzburg

 and Mannheim

.

East German cities had no 1960s-style Stadtbahn plans in place, and the fleets and the infrastructure were in need of massive investment and improvement. After the reunification of Germany in 1990, the use of the "Stadtbahn" term became popular in the former East Germany as well, as in Erfurt
Erfurt

 and Dresden
Dresden
Dresden is the capital city of the Free State of Saxony in Germany. It is situated in a valley on the River Elbe, near the Czech border. The Dresden conurbation is part of the Saxon Triangle metropolitan area....

.

"Stadtbahn" in this wider meaning is thus not a clearly defined concept, but a vague one linked to a set of attributes, much in the same way that "Straßenbahn" (tram) is linked to very different, sometimes mutually incompatible attributes. A system that is called "Stadtbahn" today may not have all of the Stadtbahn attributes: barrier-free access, higher cruising speed than tramways, doors on both sides of the train, driver's cabs on both ends, higher operating voltage, wider cars with comfortable seats, and so on.

1990s: The tram goes railway

The vehicles were designed to comply with technical specifications for the (federal) heavy railway and for light rail (communal tramways). Such vehicles are called Dual-System Light Rail Vehicles. The meaning of Stadtbahn was enlarged to encompass this new type of "tram-train

 region are differentiated more by the nature of their city-border crossings only, and not by the technical dimension (Dual-System Light Rail Vehicles). Only those services that extend into the suburbs are called Stadtbahn. They are represented by the 'S' logo that is used for 'S-Bahn' (Stadtschnellbahn) in the rest of Germany and therefore partially conflict with it, as it has acquired a second meaning in Karlsruhe.

, based on the established logos for urban metro ('U', for U-Bahn) and suburban metro ('S', for S-Bahn) and including bus ('Bus') and ferry ('F', for Fähre) operations.

As the new logos became part of the information systems at more and more main railway stations, an increasing number of cities and public transport operators came to accept and adopt the scheme. As far as the Stadtbahn terminology problem is concerned, however, the scheme serves only to add further confusion to the matter, since there is no nationwide logo for Stadtbahn services. The result appears to be a contraction in the use of the term Stadtbahn, especially in cities where it has been used in its wider 1980s 'light-rail system' meaning.

In cities where Stadtbahn has the 1960s 'pre-metro

' meaning, both the 'U' (for U-Bahn) and the 'Tram' logo are used on city maps (to indicate the location of stops) and on railway station signage (to indicate connections). The 'U' Logo is normally used both where stops or stations are underground and where they serve 'second-level' pre-metro type lines. In cities which prefix all their Stadtbahn line numbers with a 'U' (e.g. Stuttgart
Stuttgart
Stuttgart is the capital of the state of Baden-Württemberg in southern Germany. The sixth-largest city in Germany, Stuttgart has a population of 600,038 while the metropolitan area has a population of 5.3 million ....

), the 'U' logo is used at stops on services that are essentially 'classic' tram lines, not 'second-level' at all.

Regionalstadtbahn

The concept of Regionalstadtbahnen (also known by RegioStadtbahn or other names) arose as a result of the harmonisation or integration of railway lines into Stadtbahn networks. In the area of Cologne–Bonn a single operational system (of so-called above ground lines or Hochflurstrecken) was created by the Cologne Stadtbahn and the Stadtbahn Bonn, opened in 1974,
from the conversion of two former railway lines (the Rheinuferbahn and Vorgebirgsbahn belonging to the old Köln-Bonner Eisenbahnen). Further developments led to tram-train

Public perception

This description of the Stadtbahn term has been about the intended use (what decision-makers and marketers intended). The public perception of politicians, passengers has been different.

Mainly, the Stadtbahn term is much more widely used and well known among decision-makers and marketers.

Where it became clearly identified with investment and urban redevelopment, the term had some success in reaching the public, depending on whether it has still been used alongside other terms like 'U-Bahn', 'Straßenbahn' or 'U-Straßenbahn'.

Only little success in the meaning of getting widely used - instead of 'Straßenbahn' (tram) - was dedicated to most of the systems with 1980s concept of Stadtbahn. This evolution was further driven by the introduction of the 'Tram' logo and the absence of a nationwide standardized Stadtbahn logo (since for those systems without underground sections, the partially standardized 'U-Stadtbahn' logo would not be appropriate).

In most of the cities with systems that include underground, ground-level and sometimes elevated line sections, all three terms are in wide use for the whole system or to the corresponding sections: 'Straßenbahn' (tram), 'U-Bahn' (metro), Stadtbahn.

Legal terms

Although a precise legal definition of Stadtbahn was planned in the 1970s, there is currently no such definition. By law, the BOStrab
