Нужно перевести текс. переводчик не корректно выводит, тк там железнодорожный язык. from the history of the railroad track the railway track of today is different from the track, which was used in the early days of the steam railroads. the first track had no ballast; the rails were long wooden bars and they were covered with thin straps of iron. the wooden rails were put on granite blocks. the centre of the track was a path for the horses which drew the cars. this kind of track was not satisfactory for steam trains. the granite blocks were soon replaced by wooden ties. in the eighteenth century long before the steam locomotive was invented. english engineers began to experiment with rails which were made of iron. but iron rails also often broke. people of those days knew about steel. but steel is very expensive.
