Verordnung über den Bau und Betrieb der Straßenbahnen

The Verordnung über den Bau und Betrieb der Straßenbahnen ("Ordinance on the Construction and Operation of Street Railways" / light railway regulations), 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 ("Allgemeinen Eisenbahngesetz", first issued on 29.

A third law ESBO (Eisenbahn-Bau- und Betriebsordnung für Schmalspurbahnen) covers narrow-gauge railway regulations.

This is common with tram-train systems - apart from a technical switch on the boundary (e.g. EMUs need to change from 750 V to 15 kV) a different set of safety regulations needs to be followed (e.g. tramways are run on sight while main railways use block control).

Current eligibility criteria define that federal funding for railroads is only permitted for sections that have a trackbed that is at least exclusive.
