Заранее огромное откликнувшимся! нужен перевод! now there are a lot of different types of passenger cars. they are a coach, a sleeping car, a dining (restaurant) car, a lounge car, a combine car (a combination of coach and baggage car). sometimes for long journeys other types are used, such as a disco car, a theatre or a movie theatre car. as for the observation cars, they were usually put into the rear of many famous trains, so that the passengers could view the scenery. they became popular, and special dome cars were constructed to provide passengers with better view. they had a glass enclosed upper level above the roof. many innovations have been introduced in car construction since the early days. modern carriages are made of light-weight steel, aluminum and plastics. at present, most long-distance trains are furnished with fluorescent lighting and air-conditioning. so the problem of comfort is solved. now passenger cars are lighter, but they can carry heavier loads at high speed.
