A total of 211 trainsets have been built by Canadian conglomerate Bombardier at its factory in Crespin (near Valenciennes, France) since 2005. The first set (Z 27503/27504) was placed into regular passenger service on 24 March 2005, for the Basse-Normandie region.

Design
Bombardier vehicle design is articulated using bogies between carriages. The Z 27500 are available in three or four-car unit. The train can be operated as a multiple-unit control with up to three units, with other Z 27500 or the dual-mode version Diesel/ (B 81500). The train is equipped with 2 pantographs on the intermediate car.

Their capacity offers 160 seats in a three-car unit, 220 in a four-car set. The inter-carriage passages have wide, open gangway connections, limiting bottlenecking.

The Z 27500 from Lorraine region can be operated as a multiple-unit control with the Diesel variant, specifically equipped with a command to raise the pantograph.

Whereas the first trains were delivered in their three-car set version (with an intermediate car), several regions later added a second intermediate car, in order to increase their capacity from 160 to 220 seats.
