. "Line B (Ligne B) is a line on the Lyon Metro that runs between Charpennes and Gare d'Oullins. It was constructed using the cut-and-cover method, and went into service on May 2, 1978. It, together with Line A, were the inaugural lines of the Lyon Metro. It has since been extended three times: from Part-Dieu to Jean Mac\u00E9 in 1981, from Jean Mac\u00E9 to Stade de Gerland in 2000, and from Stade de Gerland to Oullins railway station in 2013."@en . . .
