As part of its renovation and expansion program, the Moscow-Sheremetyevo Airport - currently the largest airport platform in Russia with the ambition of being one of the world's largest hubs – requested ADP Ingénierie (APD-I) for the design of an underground passageway connecting all passenger terminals of the airport. This tunnel, bored under the existing runway, was to house an innovative transport system for passengers and luggage.
With the objective of transporting at least 11.5 million passengers and 5.9 million pieces of luggage a year, the client expressed his preference for either an Automatic People Mover (APM), a wire-guided system or autonomous shuttles.
