MI 79 (Z 8100)

The MI 79 (Z 8100 series) is one of the first interconnection trainsets of the RATP and SNCF networks in Île-de-France. The MI 79, designed in the 1970s for RER line B, were followed by a derived version, the MI 84, designed to meet the needs of RER line A, before being partly assigned to RER B.

With a view to the full operation of line B of the RER, without interruption of load at the Gare du Nord, the SNCF and the RATP have ordered from the Société franco-belge, the Ateliers de construction du Nord de la France and the Electro-Mechanical Company, 82 MI 79 units. The main quality of this new equipment is to be compatible with the particularities of the network, the main differences of which are, at the time of the design of this type of train, high platforms.
