The T Zen 4 enters a decisive phase

The preliminary project for the T Zen 4 Bus was approved on Wednesday 11 July 2018 by the Board of Directors of Île-de-France Mobilités. This is a crucial step since this document details all the technical characteristics of the project, and in particular the modalities of integration of the project into its urban environment.

It also incorporates the commitments made by Île-de-France Mobilités in relation to the recommendations made by the commission of inquiry following the 2016 public inquiry.

Efficient and more regular service

The Bus T Zen 4 is abus with a high level of serviceand mostly in its own lane. This means that a lane will be reserved for it, to offer a more efficient and regular service. Its length of 24 meters allows a capacity of 130 passengers per bus (40% more than an 18-meter bus) in order torespond effectively to the expected level of attendance. This project will also beenvironmentally friendly, with a hybrid NGV/electric or 100% electric engine.
