Alstom and NTL unveil the second Aptis prototype

Alstom and NTL have presented the second Aptis prototype, a 100% electric solution for mobility, in Versailles.

Aptis will be tested by the STIF and Keolis on the bus route between Versailles and Vélizy from September 2017 onwards. The tramway-like bus prioritises passenger comfort; Full low-floor and three double-doors, allow smooth on-board passenger circulation and easy access for pushchairs and wheelchairs. It has panoramic windows at the front and the rear of the bus which provide 20% extra window surface compared to a conventional bus, as well as a lounge area at the rear. Aptis also benefits from a low level of sound.

The vehicle integrates itself into urban environments through its four steerable wheels that minimize the space needed in curbs (-25% compared to a conventional bus). This insertion also reduces the space needed for parking and helps to gain extra space for other types of vehicles at bus stops.

The Aptis prototypes are manufactured at the NTL plant in Duppigheim in the Grand Est region and the main components are manufactured at five Alstom sites in France: Saint-Ouen for the project management and system integration, Tarbes for the traction, Ornans for the motors, Vitrolles for the SRS system and Villeurbanne for the electronic components of the traction chain.
