Вот что написано у самого Штадлера
In June 2014, Azerbaijan Railways (ADY, Azerbaycan Demir Yollari) ordered 30 sleepers from Stadler. They are intended for international
operation on the line from Baku (Azerbaijan) via Tbilisi (Georgia) to Kars (Turkey) and on to Istanbul (Turkey), and designed
for an service speed of 160 km/h. The route not only crosses international borders, it also involves break-of-gauge. In order for the
trains to be able to travel both on the Russian broad gauge used in Azerbaijan and Georgia, and on standard gauge used in Turkey,
the bogies developed by Stadler are fitted with variable gauge wheelsets. The 30 sleepers are split into five different carriage
types. There are 18 second class sleepers with 32 beds in four-berth compartments, 3 first class cars with 16 beds in two-berth
compartments, 3 first and second class carriages with 20 beds in two-berth compartments, and 3 second class carriages with a
compartment for people with restricted mobility. This amounts to a total of 18 beds and a dining car with 28 seats. Each car has
an emergency power unit that enables it to stay in operation up to 24 hours when the train line is not being fed by the locomotive.
Получается, что Штадлер разработал свою систему автоматического изменения ширины колеи, если точно переводить.
