Vienna's line 39A switches to full hydrogen operation thanks to CaetanoBus fleet - Sustainable Bus
"Wiener Linien announces it is expanding its zero-emission bus offer with the deployment of ten CaetanoBus H2.City Gold vehicles on Line 39A, following the introduction of battery-hydrogen buses in the city centre. The tender was awarded back in early 2024. Green hydrogen is supplied by Wien Energie, produced from renewable electricity at the Smart Campus of Wiener Netze in Simmering, enabling fully emission-free operation, the operator points out."
"Line 39A - known for steep gradients, short stop spacing and high peak-time loads - is one of the most demanding routes in the city. Its profile, in the intention of Wiener Linien, makes it a fitting environment for hydrogen buses, which combine long range with stable performance on hilly terrain. In recent weeks, vehicles and staff have undergone extensive testing and training ahead of the transition. More than 80 percent of Wiener Linien passengers are already travelling on low-emission modes."
Wiener Linien will deploy ten CaetanoBus H2.City Gold fuel cell buses on Line 39A from 1 December, expanding the operator's zero-emission bus fleet. Green hydrogen will be supplied by Wien Energie, produced from renewable electricity at Wiener Netze's Smart Campus in Simmering, enabling fully emission-free operation. Since 2024 twelve bus routes have transitioned to zero-emission propulsion using green electricity or green hydrogen. Line 39A’s steep gradients, short stop spacing and high peak-time loads make hydrogen buses suitable due to long range and stable hilly performance. Staff and vehicles underwent extensive testing and training ahead of service start.
