FS Class ALe 582

's livery. The ALe 582 project was developed in the mid-eighties in order to replace old rolling stock used for commuter traffic and medium-distance (regional and local services) 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 (and one of the very few) 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 assigned to the G.A.I. Consortium, formed by Breda Costruzioni Ferroviarie, Officine Fiore Lucania, Officine Meccaniche Stanga, Ansaldo Transporti, Firema Trasporti (bodyshell and mechanical part) and Ercole Marelli (electrical and electronics part). 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 (motor-cab car), one or two intermediate trailers (1st class Le 763 pr 2nd class Le 884) and a Le 562 (non-motor driving trailers), 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 (between Lecco and Tirano via Sondrio). 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 regulations, and also unlike the ALe 724s, which are 2nd class-only, ALe 582s may have first class (with three rows of seats) or second class (with four rows of seats) compartments. Trenord's ex-trenitalia units had their 1st class compartment declassed to 2nd, but they still keep the three rows of (and the same) seats. Intermediate trailers (Le763 and Le884s) 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" (the two motors on each bogey are connected in series, and the two bogeys are connected in 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." (Alta-Tensione, "High-Voltage" comparto) 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. (interruttore rapid o - the 3Kv main switch), 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 (two per ALe 582) 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 (between the pantographs). Air braking replaces electric one below the speed of 30 km/h. The bogeys were designed by Fiat Ferroviaria, and they use air-suspensions. == Lines served ==
