Eurostar trains had big problems on Tuesday. Many trains were stopped. This made travel hard for people.
A big power problem happened. It was in the tunnel under the sea. All trains stopped for many hours. Many travelers were stuck. Their holiday plans were not good.
The problem was with electricity. The power went out in the tunnel. A train with cars and people stopped. This made things worse.
Eurostar cancelled trains from London. These trains go to Paris and other cities.
Bad cables were the reason. The cables give power to the trains. They needed fixing fast. The power stop affected all trains.
Some car trains started later. But Eurostar trains were still late. Many people waited a long time. More stops could happen.
By the afternoon, some Eurostar trains ran. They were very late. The problems were expected all day. This made holidays sad for many.
