Disappointed with Hess and MAN: Zurich Transport Services tender for 100 electric buses

Several Swiss media outlets report that Zurich Transport Services (VBZ) is set to invest up to 140 million Swiss francs (approximately 150 million euros) in the procurement of up to 100 new battery-electric buses. The corresponding tender is expected to be published later this month. Additionally, manufacturers may voluntarily submit offers for up to 100 trolleybuses, with an estimated volume of a further 160 million Swiss francs (approximately 172 million euros).

When asked why Zurich Transport Services is not exercising options with its existing suppliers, a VBZ spokesperson expressed dissatisfaction with two of its current contractors, Hess and MAN. The spokesperson explained that trolleybuses from previous orders placed with Hess are still being delivered months behind schedule. Moreover, operational issues have been reported with the heating and ventilation systems, the powertrain, and the automatic raising and lowering of the pantographs. Meanwhile, MAN buses have been plagued by problems with the doors, chassis, and heating system.

According to VBZ, the procurement process was delayed by several months to allow both manufacturers time to improve their vehicles. Had these improvements been successful, the transport services would have exercised the options in the existing purchase agreements. However, this was not the case. The VBZ spokesperson stated that the organisation continues to face ‘significant and ongoing challenges related to the reliability of our MAN and Hess bus fleets.’ As a result, the transport services feel compelled to seek new suppliers.
