Bex–Villars–Bretaye Railway
The Bex–Villars–Bretaye Railway (french: Chemin de fer Bex-Villars-Bretaye, BVB) is a metre gauge railway line operating between the towns of Bex and Villars-sur-Ollon and the Col de Bretaye mountain pass, situated in the Chablais region of southwest Switzerland. It is, in fact, two railways, one mixed adhesion and rack worked between Bex and Villars-sur-Ollon, the other, linking Villars to the Col de Bretaye being worked on the Abt rack system. Passengers making the full journey are required to change trains at Villars. History The authority to construct the railway was gained in three stages, that from Bex, a small town on the main Lausanne–Simplon railway, to Villars-sur-Ollon on 15 October 1897; from Villars to Chesières on 19 December 1905 and from Villars to Bretaye on 5 October 1911.

Twin Unit
A twin unit or twinset is a set of two railroad cars or locomotives which are permanently coupled and treated as if they were a single unit. A twinset of cars or coaches can also be called a twin car. In US passenger railroad parlance, twin units are also known as married pairs. On passenger railroads, light rail, and monorail services, married pairs may have machinery necessary for full operation of the cars split between them. Items that are typically shared include transformers, motor controllers, dynamic braking grids, cabs, current collectors, batteries, and air compressors. This provides significant savings in both cost of equipment and weight, which increases performance and decreases energy consumption. The cost of operating such a pair may be slightly higher when the extra car in such a pair is not needed to meet level-of-service demands at a particular time.
