Interesting cars at the end of the train

The car to the left is an RhB EWI built by FFA (Flug- und Fahrzeugwerke Altenrhein), the second is a middle-entrance car in original version with perpendicular benches, the third is an MGB EWII, originally built by the FFA for the BVZ that is identical to the RhB cars, then an RhB/FFA EWII and finally an SIG (Schweizerische Industrie-Gesellschaft)-built EWII from the Furka-Oberalp. The SIG EWI had one more window after the doors and was originally designed for the SBB Brünigbahn, but built for the Berner Oberlandbahn (BOB) and the Montreux-Oberland bernois (MOB) as well.
