HJ4150 SNCF, 3-unit set of RIB 70 coaches, original livery, period IV

With the 25 kV electrification of the suburban lines in the north and east areas of Paris, there were only 4 prototype stainless steel trains whose entry into service was delayed due to lack of a successful motorization.

At the end of 1960, SNCF began experimenting with the use of these prototypes pulled by a BB 16500 locomotive. This test gave full satisfaction, thus the “Rames Inox Banlieue” was born.

If the type 62 and type 70 RIB trains were mainly used in the Paris region at 25 kV in a train of 4 (east, north) or 7 (St-Lazare) coaches, the later versions of type 76 and RIO RIB trains ordered by regions (NPDC, Alsace, PACA) were suitable for the different traction modes (double current, single-phase-diesel, double-current-diesel) and to extend their scope of use to the peripheries and around the so-called régionales métropoles.
