It is very hot in Austria. The temperature is up to 41 degrees. The train company warns people. The heat harms the rails. The heat harms the train tools.
Heat can bend the rails. Steel gets big in the heat. Then the rails bend. This is bad for trains. Trains must drive slower then.
Trains arrive late. Some tracks close for a short time. Workers check the rails more often. They use concrete beams for safety. The wires above the train also get hot.
The train company gives advice. Do not travel if you can stay home. Take water with you. Wear a hat for the sun. Look at the train app before you go.
