Naples Metro M1

The Naples Metro M1 is a rapid transit electric multiple unit operated by Azienda Napoletana Mobilità (ANM) on the Naples Metro since March 1993.
==History==
The M1 is the first generation of rolling stock operational on the Naples Metro. A total of forty-five two-car sets were manufactured from 1991 to 1992; the car bodies were manufactured by Sofer and Fiore and electrical components were manufactured by Ansaldo and Metalmeccanica Lucana. The construction of an additional ten sets was also planned, making fifty-five sets, but this was not exercised.
The M1 entered service on 28 March 1993 with the opening of Line 1 of the Naples Metro. Originally operated by Ferrovie dello Stato Italiane, Azienda Napoletana Mobilità took over operations of the line in 1995. Three sets, 025-026, 029-030 and 033-034, were rented to the newly-formed MetroCampania NordEst for use on Line 11 of the Naples Metro from 2005 to 2009 until ex-Rome Metro MA 100 cars were acquired for use on that line.
The M1 has largely been replaced by the new Mohini trains introduced since 2022.
==Design==
Car bodies are constructed of a lightweight aluminum alloy. Each set consists of two semi-permanently coupled powered cab cars; trailing cars were not added due to the steep gradients of the line reaching 55‰ in some sections. The M1s feature externally-mounted brake discs and are the only rapid transit rolling stock in Italy to use sliding doors as opposed to plug doors. Their design is based on the Rome Metro MA 100 and Milan Metro 500 series sets.
Up to three sets can be connected in a multiple unit formation at a time, this apparently being standard practice.
==Specifications==
The M1s are the first type of rolling stock on the Naples Metro to employ variable frequency drives as a traction system; a GTO system used by Ansaldo is used on the M1s, which when accelerating makes a sound similar to a car shifting gears. The GTO system is similar to the ones used on the Rome Metro MA 200 and Catania Metro M.88 models of rolling stock.
