"X7 was a series of electric railcars operated by Statens J\u00E4rnv\u00E4gar (SJ) of Sweden as local trains. 26 motor cars were built, with an additional 22 trailers, by ASEA in 1949-51. They were put into service on the predecessors to the Sk\u00E5ne and Gothenburg commuter rail systems. The X7 was in service until 1983, when it was replaced with X10."@en . "X7"@en . "1949Z"^^ . . .
