| Gauge change installation. The train can pass with a speed of 15 kmh / 9.3 mph for chaning gauge. Other companies have also equipped their trains with variable bogies, such as the Spanish Talgo. However, the bogie designed by MOB and further developed by Alstom is the only one with such a strong widening (from 1 m to 1.435 m, i.e. by +43.5 %) and a simultaneous increase in the body of the car from 350 mm to 550 mm. No other bogie with variable track gauge is able to do this. |
