SNCF Class Z 5300

SNCF Class Z 5300 are three and four car Electric Multiple Unit type for Paris commuter and regional services. They were built by Carel et Fouche, Matériel de traction électrique/Francorail, Fives-Lille and OC Oerlikon between 1965 and 1968 (1st batch) and 1972 and 1975 (2nd batch). Many of these trains have been withdrawn starting from 2003.

Characteristics
These stainless steel-bodied EMUs were built as 4-car units including a driving motor car, two intermediate trailers and a driving trailer. However, some units were shortened to three or two cars by removing one or both of the intermediate trailers. Up to three elements can be coupled together to form a 12-car trainset. The power supply is 1500 V DC with electromechanical traction equipment.

Livery
As the use of stainless steel eliminates the need for painting; the units are silver, with originally only an orange stripe between the headlights. They are therefore nicknamed petit gris (i.e. "little gray", but also the name of a snail), couscoussière, "silver arrow" or "tin can". However, as some units were modified, the doors were painted red, light blue or dark blue according to the services they were intended for.

Since 2011, only red-doored units subsist; red doors mean that the unit is fitted with EAS (exploitation à agent seul, i.e. "single crew operation"), and may be operated without a guard.
