A new type of bus is about to see the light of day in Île-de-France. Called the Tzen 4, this 24 meter long and 100% electric bus will replace the current line 402 on a 14 km route in Essonne. Announced as a world first, the entry into service of this “bi-articulated bus” is expected for the year 2025.
Over the next few weeks and months, public transport in the Ile-de-France region will bring about new changes. Opening of the Villejuif – Gustave Roussy station on line 14, commissioning of the first cable car in Île-de-France or even the arrival of new trains on line 10 of the metro… users will be able to discover several new features in 2025 , before the inauguration of line 15 South of the Grand Paris Express, now announced for summer 2026.
Another novelty should get people talking. Have you ever heard of Tzen 4 ? Advertised as “ a world first », the Tzen 4 is a 100% electric bus with a length of 24 meters. It should replace, during 2025, the current bus line 402 over 14 km in Essonne. In detail, the Tzen 4 will circulate between “La Treille” to Viry-Châtillon and the RER station of Corbeil-Essonnesconsidered the “ the busiest section of the greater suburbs », according to Île-de-France Mobilités.
Much more than a simple bus, the Tzen 4 is a “ bi-articulated bus » which can accommodate up to 140 people, compared to 100 in the buses of the current line 402. In addition to being “ more comfortable “, this new bus is also intended to be “ more efficient ”, thanks to dedicated lanes on a major part of the line and priority at intersections, but also “ more environmentally friendly ». The Tzen 4 will circulate in this way thanks to a “ ground charging in less than 5 minutes » !
According to Île-de-France Mobilités (IDFM), more than 40,000 travelers are expected every day on the Tzen 4. 5 municipalities will be crossed (for a total of 30 stations), with strategic districts served, such as the Grande Borne district and the ZAC Center-ville in Grigny, the Plateau and Canal districts in Évry-Courcouronnes, the Hospital Center South Francilien and the Montagne des Glaises ZAC in Corbeil-Essonnes.
