The ALn 668 (Automotrice Leggera a nafta, Light Diesel motor car) series is a family of diesel railcars built by Fiat Ferroviaria between the 1950s and the 1980s. The trains were built for the Italian public railway company Ferrovie dello Stato (FS), now Trenitalia as well as many Italian private railway operators. Types derived from the class have been built for the railway companies of other nations. Most of the trains are still in service today.
The forty units of the 2400 series were built entirely by Breda in Milan.
The ALn 668 is considered the standard railcar of the FS. Class ALn 663 is quite similar, while maintaining the same mechanics, received a different classification exclusively for the new interior design that reduced the number from sixty-eight to sixty-three.
