How can you get from England to France in just 20 minutes? Travel in the Channel Tunnel. This railway tunnel runs underneath the English Channel, the body of water that separates England and France, and

tunnel opened, the design proved to be a good one-fire broke out in a train coming from France and
everyone was able to escape through the service tunnel
