The Metropolitan Railway (MetR) and the Metropolitan District Railway (District) were the first two underground railways to be built in London, creating the world's first metro system. Although separate and independent companies and often fierce rivals, the histories of the MetR and the District are inextricably linked through their joint construction of the Inner Circle (now the Circle Line). These two railways formed the basis of what would later become known as the London Underground network.
