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.
Lots of FS's fleet was destroyed at the end of World War II, which meant the company needed a replacement diesel railcar. The essential characteristic of the new rolling stock was the provision of the drive motor under the floor, so as to leave the maximum space available for passengers.
The railcars RALn 60, built for the modernization of passenger service on the lines of the Sicilian FS 950 mm (3 ft 1 3⁄8 in) Narrow gauge railway, were tested from January 1950 and was the start of the long line of railcars built by Fiat from the war until the first half of the nineties.
Although the behavior of new railcars was overall satisfactory, availability and maintenance costs were still very far from the objectives considered within the Service Material and Traction for FS, which had long aspired to the creation of a standard Italian railcar standard.
By building on the experience already acquired in 1954 initiated the project for a new standard railcar, for which the FS established clearly the fundamental objectives: high reliability, ease of conduct and learning, maintenance and repair well-programmable, overall costs contained defined and relatively modest, given the kind of services that diesel railcars were called upon to play in a network where it had planned the electrification of all main lines.
