Hitze horror in Cologne: This is how passengers torture themselves in KVB tracks!
Ehrenfeld, Deutschland - Today, on July 1, 2025, it gets really hot again in Cologne! The Cologne Verkehrsbetriebe (KVB) recently released a list of which city railways are equipped with air conditioning systems. But many passengers of urban transport often experience an unpleasant journey at outside temperatures above 25 degrees. In particular, the tracks of the 2200 and 2300 series not only have no cool breeze, but are also notorious for their hot temperatures and the associated “sauna rail” experiences. The KVB also mentions the unpleasant smells and glued seats as frequent problems in heat mobil.express.de.
Did You Know that the KVB has a total of 299 buses in use and 225 of them are air -conditioned? That corresponds to about 75 percent. But even in the buses, it can get uncomfortably warm at high outside temperatures, since the air conditioning systems are affected by regularly opening the doors. On average, the doors open every two minutes and let the heat in, which makes the cooling more difficult [blog.kvb-koeln.de] (https://blog.kvb-koeln.de/von-klimaanlagen- und saunahen).
What are the lanes?
The KVB service teams have equipped the series 2400, K4500, 5100, 5200 and 5300, about 47 percent of the city railways, with air conditioning systems, but are not sufficient to effectively lower the temperatures. As a rule, the railways can only reduce the internal temperature by three to six degrees. The high visitor frequency, caused by the numerous stops, also creates the air conditioning systems mobil.express.de.
- lanes with air conditioning:
- series 2400
- Series K4500
- series 5100
- series 5200
- series 5300
- lanes without air conditioning:
- series 2200
- series 2300
- series K4000
The KVB plans to replace the older series 2200 and 2300 with new, air -conditioned models in the next five to ten years. However, it is not possible for static reasons to retrofit the air conditioning systems-another point that should give passengers to think [blog.kvb-koeln.de] (https://blog.kvb-koeln.de/von-klima facilities- und sauna trolley).
pandemic of the heat: what to do at extreme temperatures?
The outcry of passengers is unmistakable on social media: Why are the air conditioning not switched on? In fact, the air conditioning systems are activated in the operational vehicles when they are available. In the case of older models, the passengers only have to open the windows, which in a city like Cologne, where fresh air is often in short supply due to the lack of green areas, does not really help. If the mixing of hot air with the cooling tests of the air conditioning systems is added, the trip quickly becomes a sweaty endurance test for everyone involved [blog.rnv-online.de] (https://blog.rnv-online.de/macht-mal-die-klima facility-an/).
The KVB has already taken important steps in recent years to improve the experience for its travel guests. The city railways of the series 2400 were completely renovated and equipped with modern air conditioning systems. The 5300 flour railways also use a revocation system that saves energy. But in view of the current weather, there is still a lot of room for improvement, since the climate systems are also heavily contaminated by frequent opening of the doors and the heat output of the passengers [blog.kvb-koeln.de] (https://blog.kvb-koeln.de/von-klimaanlagen- und sauna lags).
The KVB therefore faces the challenge of satisfying the passengers even with minus degrees in winter and tropical temperatures in summer. Because ultimately everyone wants a cool place on the way to work or for leisure activities - and not just in an air -conditioned car, but also in the lanes and buses that are promoted tens of thousands of Cologne every day.
