The Leipziger Verkehrsbetriebe or LVB, literally translated into English as the Leipzig Transport Company, operates the tramway and bus transport services in Leipzig, Germany. The LVB route network is a part of the regional public transport association Mitteldeutscher Verkehrsverbund. LVB was formed by the merger, from 1 January 1917, of two predecessor undertakings, the Großen Leipziger Straßenbahn (GLSt, "Greater Leipzig Tramway Company") and the Leipziger Elektrischen Straßenbahn (LESt, "Leipzig Electric Tramway Company"). The merged undertaking was also known as GLSt until it was reorganized and renamed as the LVB, from 29 July 1938.
