The heat in the public transport, 40 degrees?

Munich’s U-Bahn lines 3 and 6 will operate normally during the Oktoberfest despite extensive renovation work, according to officials. The city’s utility company, Stadtwerke München, confirmed that the two lines will run without restrictions starting Saturday, September 19, and continue until October 4. This marks a key milestone in the ongoing modernization efforts at two central stations, Poccistraße and Goetheplatz, which require major repairs due to their age and condition. The renovations involve comprehensive upgrades to the infrastructure of these stations. Work began earlier this year, with initial phases involving partial service disruptions. These disruptions were necessary to allow crews to carry out essential maintenance tasks such as reinforcing structural elements, replacing outdated equipment, and improving accessibility features. The project has required careful coordination to ensure that public transport services remain as reliable as possible throughout the process. Once the regular operation resumes on September 19, the lines will run under normal conditions for nearly three weeks before transitioning into a phase of limited service. During this time, the track section between Sendlinger Tor and Implerstraße will be operated on a single track, which will reduce capacity and potentially cause delays. This one-track operation is scheduled to last for approximately two months, after which there will be a brief period of normal operations between late November and mid-April 2027. Following this, another shutdown is planned, lasting until August 2027, during which passengers will need to rely on replacement buses instead of the U-Bahn. The decision to conduct these works during the summer season reflects both the complexity of the task and the timing of the city’s infrastructure plans. While the Oktoberfest represents a peak travel period, the city opted to prioritize the completion of the project ahead of schedule rather than delay it further. Officials emphasized that maintaining service continuity during this high-demand period was a critical goal. Meanwhile, in Berlin, extreme heat has continued to pose challenges for public transportation systems. Although temperatures reached 40 degrees Celsius in early June, the impact on the city’s rail network remained manageable. However, officials acknowledged that rising temperatures could become a more frequent issue in the future. A recent inquiry by Green Party representatives highlighted concerns over the long-term effects of heat stress on infrastructure and passenger comfort. Berlin’s public transport operators reported minor technical issues linked to the heat, including deformed rails, faulty signaling systems, and overheating of vehicle climate control units. Some regional trains had to make unscheduled stops due to locomotive cooling requirements, while electric buses occasionally experienced malfunctions related to battery cooling. Despite these incidents, overall service disruption levels were described as “controlled” by transport authorities. The lack of historical data comparing current heat-related disruptions with past years has raised concerns among critics. Without comprehensive records, it is difficult to assess how frequently such problems might occur in the future. Nevertheless, new train models being introduced by the S-Bahn and tram operators are designed to function reliably even at higher temperatures. However, user comfort remains a challenge, particularly in older vehicles, which lack air conditioning. Transport planners in Berlin have begun developing strategies to address the growing risks associated with climate change. While immediate measures are still under consideration, the focus is shifting toward longer-term planning. With increasing summer temperatures projected, cities like Munich and Berlin face the dual challenge of upgrading aging infrastructure while preparing for the environmental changes that lie ahead.
