Heatwave Melts Track Sealant and Halts Leipzig Trams

Overview

• Leipzig's tram network remains suspended as of June 30, 2026, while the city transport operator LVB inspects routes and begins clearing and repairing melted sealant and asphalt from tracks.
• LVB says sealing mastic and softened asphalt flowed into switches and onto rails and was dragged along by tram wheels, creating obstructions that made safe operation impossible.
• The heat also sidelined part of Leipzig's bus fleet and overloaded supermarket refrigeration systems, and other German cities reported rail joint damage and concrete road deformations.
• French authorities recorded roughly 1,000 excess deaths over three days during the same heat episode, highlighting immediate public health strain across Europe.
• Officials and experts have started damage surveys and emergency fixes and are discussing revised material specifications and design standards to make transport and roads more heat resistant.
