Since 2007 high-speed trains have become a common type of transport in Europe. They make it possible to cut travel times by hours. The trains travel at 350 kilometres an hour, and this is not the limit! The only problem for the engineers is the loud noise the trains produce. People living in the areas the trains travel through suffer from the noise greatly. For the passengers, the situation is different. For their comfort, all the carriages are made sound-proof from the inside. Travelling on high-speed trains is comfortable and pleasant. In the future, a high-speed railroad network could cover most of Europe. For example, a trip from Paris to Rome could take only 3 hours!
