HESS, the Swiss bus manufacturer, has received a strong intake of new orders. The latest example is from VBZ, the public transport operator for the city of Zurich. To meet the high demand, HESS will start a new additional plant in Porto (Portugal) in December 2022.
In the next few years they will be replacing their fleet of trolleybuses. After an international call for tenders, HESS was awarded the contract, which is a worth a total of about 330 million Swiss francs. It was only a few weeks ago that the French cities of Nancy and Clermont-Ferrand plus the Austrian city of Salzburg had ordered e-buses from HESS, while last spring it was the Swiss cities of Neuchâtel and La Chaux-de-Fonds.
The first delivery for VBZ comprises 13 articulated battery-powered trolleybuses and 13 HESS lighTram® bi-articulated battery-powered trolleybuses. The new HESS lighTram® buses will be running on VBZ routes from 2024. In subsequent years there are plans for up to a further 140 vehi-cles, i.e. 85 lighTram® 19 DC and 55 lighTram® 25 DC buses. The contract also includes part of the preventive maintenance of the vehicles by HESS.
The new vehicles require less energy and will allow further diesel routes to be operated electrically. They are recharged during the journey under the existing overhead lines without loss of time. The innovative energy management system allows the integrated optimisation of all energy consumption on board the vehicles. Having everything from a single source guarantees the customer maximum flexibility in the event of changing conditions over the long service life of the vehicles.
The new design increases the attraction of public road transport both in terms of the image of the city and during use. The internal layout facilitates an efficient flow of passengers and generous standing areas by doors 2, 3 and 4.
