Repeat Incident in Jena-Ost
The incident on Thursday morning brings back memories for residents and regular passengers: just over a year ago, a tram derailed at the same stop in Jena-Ost. In the current incident as well, public transport users had to accept delays and route adjustments. The exact physical circumstances that led to the wheelsets jumping out again at this specific point are likely to become the focus of the Jenaer Nahverkehrsgesellschaft once more.
Background Knowledge: Trams and Rainy Weather
The fact that rain is cited as a trigger for derailments is often due to the specific nature of the track systems in combination with environmental influences. On the metallic rails, the onset of precipitation – often mixed with road dust, pollen, or leaves – forms an extremely slippery film of lubricant. This massively reduces the static friction (the so-called grip) between the steel wheel of the tram and the rail. Braking distances increase, and loss of contact can occur more easily in curves or switch systems.
The Jenzigweg stop is located in the densely populated district of Jena-Ost and is an important connecting axis for commuters at the foot of the prominent Jenzig. When trams on this route fail or are blocked, it often affects a large part of the tram traffic east of the Saale.
