The introduction of hydrogen trains as an alternative to diesel in the Taunus region is facing ongoing difficulties, causing disruptions for passengers.
The large-scale pilot project aims to reduce CO2 emissions, but has encountered various setbacks, including delivery problems, technical issues, and a shortage of staff.
Out of the planned fleet of 27 hydrogen trains, only 12 are currently in operation, according to the Rhein-Main-Verkehrsverbund (RMV), the regional transport authority. The RMV expects to receive four more trains in June, with the goal of having the entire fleet operational by September. Once fully implemented, the hydrogen trains will be deployed on three additional routes.
Originally, the Taunus route (RB 15) was intended to host the world’s largest fleet of hydrogen trains when the timetable changed in December. However, delivery issues prevented the full launch of the fleet. The trains that were delivered faced reliability problems and required significant overhauls. The RMV reports that the trains have become more stable since then.
To compensate for the missing hydrogen trains, diesel trains were temporarily used, but they also proved to be unreliable, causing operational disruptions. In addition to technical challenges, the operator Start, a subsidiary of Deutsche Bahn, is now facing a shortage of staff. Around 20 out of the approximately 60 engine drivers have resigned, and almost 20% of the remaining staff are on sick leave. Shift planning has become difficult due to the vehicle and staff shortage.
The manufacturer Alstom, when questioned about the reasons for the project’s setbacks and delays, cites the impact of the COVID-19 pandemic and the Russian war of aggression in Ukraine. These events created unprecedented bottlenecks in terms of staff and materials, resulting in longer-lasting effects than initially anticipated. Alstom has not disclosed the additional costs incurred, but it is responsible for covering the expenses of the replacement bus service that is currently in use for safety reasons, according to the RMV.
Once all the trains are delivered and the project runs smoothly in the long term, valuable lessons will be learned. However, the current focus is on ensuring that all trains are available and that commuters in the Taunus district can rely on a safe and reliable transportation service, as stated by the Alstom spokesperson.
While construction work is currently underway on the RB 15 line between Friedrichsdorf and Brandoberndorf, resulting in a temporary closure, the RMV has announced that it will offer free transportation on the route in August and September to compensate for the inconvenience caused to passengers.
The hydrogen train project in the Taunus region holds great promise for reducing CO2 emissions and transitioning to a more sustainable and eco-friendly transportation system. However, it is clear that significant challenges need to be addressed, including improving delivery reliability, resolving technical issues, and ensuring an adequate and stable workforce. Overcoming these obstacles will be crucial for the success and long-term viability of the hydrogen train initiative.
