The bogies are related to the type used on the TGV trains; in addition to the changes to traction motor type and installation, the bogies are constructed of a high tensile steel, for lighter weight, the bogie wheelbase is 3m as with the TGV. Braking is by rheostatic braking and regenerative braking, in addition to triple disc brakes on trailer bogies for low speed braking. An eddy current brake was not fitted. The train also incorporates a carbon composite as a structural element, forming a U beam which supports the carriage body end on the secondary suspension.
