Verordnung über den Bau und Betrieb der Straßenbahnen


The Verordnung über den Bau und Betrieb der Straßenbahnen, abbreviated as BOStrab, is a German law regulation governing the field of tramway, metro and light rail operations.
The orders are enacted by the Federal Ministry of Transport based on enabling act through the General Railway Law. The supervisory authority is delegated to the Federal Railway Authority of Germany.
The BOStrab regulations are not as strict as the EBO main railway regulations; for example the BOStrab does not specify a strict loading gauge to follow. A third law ESBO covers narrow-gauge railway regulations. The distinctions for these light rail systems are slightly different from in the UK Tramways Act 1870 / Light Railways Act 1896.
Some Stadtbahn systems are subject to both BOStrab and EBO regulations as their vehicles use both types of networks. This is common with tram-train systems - apart from a technical switch on the boundary a different set of safety regulations needs to be followed.

Trackbed

The § 16 BOStrab defines the legal types of trackbed:
If the tramway is street running or the crossings of the exclusive trackbed do not fit in the scope of § 20 BOStrab then tramways are limited to a maximum length of and a maximum width of.
Current eligibility criteria define that federal funding for railroads is only permitted for sections that have a trackbed that is at least exclusive.
