According to the Environmental Noise Directive, a main railway line is a railway line with a traffic volume of more than 30,000 trains per year (see Article 3, paragraph o). The EU Commission should all railways are reported with a traffic volume of more than 60,000 trains per year to 30 June of 2005. This notification is to be updated every five years (see Article 7, number 1, paragraph 2).
There is a definition of main and branch lines in the Railway Construction and Operating Regulations (EBO). Section 1 (2) reads:
With the new version of the operating regulations (BO) from 1958, the permissible speed was increased to 140 km / h.
With the new version of the EBO from May 1967, the permissible speed on branch lines according to § 40 (2) EBO was increased from 60 to 80 km / h and on main lines from 140 to 160 km / h. This meant that exceptional approvals from the Federal Minister of Transport for the Rheingold and Rheinpfeil trains were no longer necessary. For journeys at over 140 km / h, the Federal Railroad issued preliminary guidelines in 1962 for the planning and implementation of train journeys between 140 km / h and 160 km / h .
With the Third EBO Amendment Ordinance in May 1991, the maximum permissible speed for passenger trains on main lines was increased from 160 to 250 km / h. This meant that there was no longer any need for an exceptional permit, especially for intercity trains running at speeds of up to 200 km / h.
Main lines are defined in Section 4 of the Railway Act 1957:
Since no regulation according to § 4 Paragraph 1 Z. 2 of the Railway Act has been issued to date, the total of the Austrian main railways results from the 6 ordinances issued by the Federal Government in accordance with § 1 of the High Performance Lines Act.
In Swiss law, there is no longer a distinction between main and branch lines. With the revision of the Railway Act of 2009, the distinction was abandoned.
Before that, until 2009, according to the former Art. 2 of the Railway Act:
In Scandinavia, depending on the national language, the term Stammbahn is used in the translation . Its definition does not take place as in Germany with the comparison of the terms main line and branch line . In the respective countries these are routes which, according to the original definition, connect parts of the country with one another .
Normally, they have the standard of main railways, but do not cover a basic network, as in the German definition, but must be viewed at a higher level.
Originally the trunk lines were introduced in Sweden in 1854 by a parliamentary resolution of the Swedish Reichstag . Back then, it was stipulated that a country's main lines would be built by the state, unlike other lines that were supposed to be built by private companies and consortia . Main lines were built in Sweden from 1856 to 1892. The construction of main lines did not end there. In the early 1900s, new lines had to be built, especially in the north. However, like the Inlandsbahn, these were no longer called trunk lines.
Banedanmark uses the term Hovedbaner in Denmark , but defines it as follows: "Hovedbaner udgør det overordnede banenet, der binder landsdelene sammen" ( German: "Hovedbaner denotes the higher-level railway network that connects the different parts of the country." ). In addition, Banedanmark uses the definition regional banners , which connect large cities such as Aalborg and Frederikshavn with the standard of a main line that is used in Germany. Pure branch lines are called sidebaners in Denmark .
The legal definitions often do not match the everyday language . A rail connection that is viewed as a branch line in public opinion can legally be a main line or vice versa.
- Long-distance trains usually run on main lines, but some important tourist destinations only reach long-distance trains via branch lines.
- Many main lines are double-tracked , but there are also single-track main lines and double-track branch lines.
- In certain countries, many main lines are electrified , but only a few branch lines.
