The track is one of the basic features of a railway. It is called the permanent way. The fact is that in the early days of railroad workers building the fist had to lay temporary tracks to transport the materials to the construction site. And only after that they laid down the permanent tracks or the permanent way, as it was called. The permanent way consists of rails, ties, and ballast.The railroad track of today is quite different from that used in the early days of the railways. The first tracks had no ballast the rails were made of wood and rested on heavy blocks of granite. Then the wooden rails were replaced by iron ones, and the granite blocks were replaced by wooden ties or sleepers. This kind of track however was not strong enough for heavy steam trains. The discovery how to make cheap steel was of great importance to the railways for, when placed in the same track steel rails had a life time 15 as long as iron rails.The distance between the rails is called the gauge. The standard gauge in most countries is 1.435 mm while in Ukraine the railroads have a gauge of 1,524 mm. That gauge was finally adopted when the first main-line Moscow-St. Petersburg railway was under construction. Thus Russia was the world's first country where the uniform gauge was adopted for all railways. In America, the gauge was unified only in 1886.The place where the ends of the rails in the track meet is known as the rail joint. The rail joint has always been the weakest part of jf the track for nearly all rails wear out first at the ends.Some railroads have two or more tracks. In order to make the trains pass from one track to another the railroads have a switch which is a very important element of the track.
