The ALe 582 is an Italian Electric multiple unit designed for Commuter and medium-distance services, developed in the mid-1980s to replace pre-war and immediately post-war EMUs and locomotive-hauled trains on various lines in Sicily and Southern Italy, although they later diffused on the whole FS network. They're part of the "ALe Elettroniche" or "G.A.I." family, together with their predecessors ALe 724 and their successors, the ALe 642. While "ALe 582" is usually used to refer to the whole trainset, it officially indicates only the motor-cab car: the trailers are classified Le 562, Le 763 or Le 884.
History
The ALe 582 project was developed in the mid-eighties in order to replace old rolling stock used for commuter traffic and medium-distance on secondary lines of Sicily and southern Italy. It is a strict derivative of the ALe 724 Class, which was introduced in 1983 for commuter services around Naples, Milan and Turin. The most noticeable difference from the ALe 724s is the redesigned FRP-made cab front, designed to cope with new crash-worthiness regulations. The order of the first batch was placed in mid-1984 and deliveries began in 1987, with production assignedd to the G.A.I. Consortium, formed by Breda Costruzioni Ferroviarie, Officine Fiore Lucania, Officine Meccaniche Stanga, Ansaldo Transporti, Firema Trasporti and Ercole Marelli. They were delivered in the striking "MDVE" red, orange and dark grey livery, and between the late '90s and the early '2000s they were repainted in the new Trenitalia XMPR livery. Starting from 2009, ex-Trenitalia units handed over to Trenord received the latter's dark green and white livery. The trains are usually formed of an Ale 582, one or two intermediate trailers and a Le 562, forming 3 or 4-car sets in Mc-R-R-Rc or Mc-R-Rc formation. Infrequent compositions also include 2-car sets in Mc-Rc formation or "double-motored" Mc-R-R-Mc formations. In 2014, 6 ALe 582 were renewed by Trenord for use on the Valtellina Railway. After the renovation, each received the name of a regional mountain peak.
Technic
One of the most striking changes compared to ALe 724 is the front part, which is made in FRP, to cope with then-new crashworthiness regulationss, and also unlike the ALe 724s, which are 2nd class-only, ALe 582s may have first class or second class compartments. Trenord's ex-trenitalia units had their 1st class compartment declassed to 2nd, but they still keep the three rows of seats. Intermediate trailers are not equipped with toilets. All the traction equipment is concentrated on the ALe 582 motor-cab cars, which are equipped with four nose-suspended motors, two per bogey, permanently combined in "semi-parallel". Gears provide the transmission from the motor to the wheel, using a 30/75 gear ratio. The electronics and traction control equipment is concentrated in a dedicated compartment, called "A.T." located between the driving cab and the first passenger door on ALe 582. The compartment houses the GTO chopper traction control, manufactured by Ercole Marelli and similar to the one used on ETR450s, the I.R., the transformer, the fuses and other important equipment. Coupler adapters, short-circuiting bars and other emergency or maintenance equipment is also stored in the A.T. compartment. The pantographs are of the Type 52, one of the FS-designed unified-type pantographs. Braking is electro-pneumatic, managed by an Oerlikon-made controller. Like all the other G.A.I. EMUs, ALe 582s are equipped with regenerative brakes; regenerated electricity can either be sent back to the catenary or dissipated on the resistors located on the roof of the ALe. Air braking replaces electric one below the speed of 30 km/h. The bogeys were designed by Fiat Ferroviaria, and they use air-suspensions.
