Continuous welded track
Continuous welded track was developed in response to the observation that the bulk of track maintenance work takes place at the joints. It is worth mentioning that jointed track has suffered from buckling in the past; the fishplates need to be removed and greased annually (the requirement was relaxed to bi-annually in 1993).
Where this was forgotten or where ballast conditions were especially weak, buckling took place in hot weather.
As steel production and manufacturing processes improved, the rail lengths installed were progressively increased, and the natural consequence of this would be to eliminate the joints altogether.
A major obstacle to doing so is thermal expansion: the rails expand in higher temperatures. Without joints, there is no room for the rails to expand; as the rails get warmer they will develop an enormous force in trying to expand.
The CWR is installed and fastened down at an optimum temperature, to ensure that the highest possible expansive force is limited. In the UK this temperature is 27 C°.
The CWR rails are made by welding ordinary rails together. For many years rails could only be made in lengths of up to 60 ft (18 288mm) in Britain, and the factory welding process made them into 600, 900 or 1200 ft lengths, depending on the factory. The process used was a flash-butt process in which high electric currents are used to soften the rail end, and the ends are then forced together. The flash-butt process is very reliable, providing that the factory ensured good geometry of the rail ends.
The long rails could be conveyed to site by special trains.
The long rails had to be welded together (or to adjacent track) using a site welding process, and after initial experimentation the proprietary thermit welding process was used.

Ex.3. Translate the sentences into Russian.
A number of companies sell composite railroad ties manufactured from recycled plastic resins, and recycled rubber. These ties are said to outlast the classic wooden ties.
Plastics composite PermaTiesTM ties are exceptionally durable; they are ideal for harsh, extreme industrial manufacturing or mining track conditions.
We invite you to compare the composite ties to wood, concrete and other composite ties and see the advantages for yourself.
Concrete is a substance used for building that is made by mixing sand, small stones,
cement, and water.
Concrete is a building material made from a mixture of broken stone or gravel, sand, cement, and water, which can be spread or poured into moulds and forms a stone-like mass on hardening.
The drainage system over some sections of route has had to be refurbished or renewed.
Drainage of track is the most important factor for the proper maintenance of track. Water softens the formation unless it is drained away as soon as it falls on the track.
Regular examination, inspection and routine maintenance of drainage systems is essential.
Neglect of drainage problems will inevitably lead to track problems.
If the permanent way or track structure is to be maintained at a suitable standard for the passage of freight or high speed passenger trains, adequate drainage must be installed in new or upgraded track and existing drainage must be maintained so that it works effectively.
The one drawback (disadvantage) to concrete is that because of its rigid qualities it does not have the same flexibility as wood, or even composite ties.
Heavy stone blocks used as early sleepers offered little flexibility and were replaced by timber sleepers.
Railroad ties are being made out of plastic now.
Axion International Holdings has won a $957,000 contract to provide the U.S. Army with two bridges made from a recycled plastic. Axion says that its recycled plastic railroad ties are actually longer-lasting that typical creosote-treated wood railroad ties.
