SJ Y1 Diesel Multiple Units

The Y1 diesel railcars of the Swedish Railways are directly derived from the Italian ALn 668 1800 series. They maintain the same layout on a technical level but differ in the internal layout and in the type of transmission, wich is using the automatic gearbox. Over time, improvements have been made such as: - repositioning of the radiator, with appropriate air intake box. - replacement of the two Fiat engines in place of a pair of Volvo engines (in the 90s). - replacement of the gearbox with a modernized type. A small serie of railcars were supplied with a baggage compartment, classified as YF1. Later, with the liberalization of swedish rail transport, the railcars were managed by various "local" operators. Once their operational service was over, the railcars were sold to the railway administrations of Uruguay, Croatia and Kosovo.
