Automatische Übersetzung. Originaltext in: EN - Original anzeigen The intermediate cars from the M7 series closely resemble the M6 passenger coaches, as they share common design elements.

The 1st class interior features notable changes, including artificial leather seats in cushion form, partition walls, and 220 V power outlets. Unlike the M6, there is no dedicated 1st class passenger coach, only the upper deck of the AB units is designated as first class.

The second class shows slight improvements with 220 V power outlets at each seat but remains similar to the M6.

The "New Look" grey livery also undergoes minimal changes compared to the M6, with the 1st or 2nd class designation prominently displayed on the sides.

M6 cars returning from maintenance now resemble the M7 models to allow for mixed operations in train sets. One distinguishing feature between the M6 and M7 models, aside from the driver's cabs, is the rounded angle at the bogies on the M7, which is not present on the M6. / Quellen: https://ferrovia.be/Trains_Materiel_Tracte_Voyageurs_SNCB-NMBS_HLE-HV_M7.php
