HistoryThe project ALe 582-763 Le-Le-Le 884 562 was developed in the mid-eighties in order to replace old rolling stock used for commuter traffic and average distance of the secondary lines of Sicily and southern Italy. Conceptually, it is an evolution of the previous project of the FS Class ALe 724 of which is the version with increased interior comfort with performance very similar and with which it is coupled to multiple command. The order of the first batch was made in mid-1984 and deliveries began in 1987 Six specimens were also purchased by the Ferrovie Nord Milano, who received them over in 1993, classified in Group E 750. The contracts for the construction have been entrusted with regard to the mechanical part and the carriage at the Breda Costruzioni Ferroviarie di Pistoia, Officine Fiore di Caserta, Officine Meccaniche Stanga and for the electrical part to Ercole Marelli, Ansaldo Transporti, Firema Trasporti. The livery that was adopted was of trains and rolling stock MDVE to medium distances, with sidebands in Grey Orange and Red. Since the mid-nineties for these carriages has been gradually adopted the livery XMPR unified. The trains are usually made with a tractor Ale 582, one or two towed at intermediate Le 763 and Le 884 and a tow pilot Le 562; or with a tractor and a towed pilot; the traction system is full chopper closely similar to that used for the ETR 450. In 2014, 6 ALe 582 (in FNM version) were delivered to the Valtellina Railway (between Lecco and Tirano via Sondrio) and the trains are named as:
The interiors where redone and revisioned. DescriptionsOne of the most striking changes compared to ALe 724 is the front part is made according to the new specifications for safety reasons and polyester reinforced with fiberglass for easy installation and reduced maintenance. The interiors include two separate rooms, 1st class with three rows of seats very comfortable and form larger and 2nd class with four rows of seats for trucks, which are devoid of retreat situated on the other hand, towed, only 2nd class. The electrical part, very similar to that of ETR 450, provides for two motors for each bogie, suspended elastically by the nose resting on the one hand and on the other on an axis concentric to the wheel axis corresponding cable; the engine transmits the motion to the latter by coupling gear, with gear ratio 30/75; in turn the axis cable transmits the motion to the wheel axis by means of the interposition of rubber blocks. The motors are permanently connected in series two by two. The possible combinations are then two, four motors in series for starting and driving at low speed or two branches in parallel for each of the two motors driving fast. The power control of the engine is made entirely by electronic means through Chopper controlled by fixed frequency modulators. In case of failure of a modulator is possible to continue driving with the exclusion of the same. The socket from the airline through two pantographs of the unified type FS 52. The devices are placed in a high voltage cabin located behind the cab front. The brake is electric combined. The action is automatic braking intervenes at high speeds or power dissipation recovery, while low speed is added to the air with strains of electromotive wheels and disc brakes on towed.
