Milan Metro 100 series

The Milan Metro 100, 200, 600 and 700 series, colloquially known as the Tradizionali, is a rapid transit electric multiple unit operated by Azienda Trasporti Milanesi (ATM) on the Milan Metro since November 1964.
==History==
The 100 series is the first generation of rolling stock operational on the Milan Metro's Line M1. A total of 349 cars were manufactured from 1962 to 1989 by numerous different manufacturers in nine different batches.
The trains entered service on 1 November 1964 with the opening of the line. Most have since been withdrawn and replaced with the newer Meneghino and Leonardo trains although a number of sets still run on the line, specifically sets part of the fourth, fifth and seventh to ninth batches. Some of the sets have since been refurbished with LED headlights and destination displays.
==Design==
The 100 series is an early design of rapid transit train operated in Italy and one of the first built. Originally formed in two- or four-car units consisting of entirely powered cars, these were extended to three- and five-car units with the addition of a non-powered intermediate car. The sets which currently run are coupled in six car formations.
They are equipped with both third rail collector shoes and pantographs; the latter is only used in depots.
==Specifications==
The 100 series uses a rheostatic control system manufactured by either Ansaldo or Ercole Marelli. A number of sets were refurbished to use armature chopper control systems in 2005.
==Incidents==
Numerous cars were part of an arson attack in 1982. Following this their seating was made of a fireproof material.
