1. The existing individual machines for track maintenance are being combined together, forming complex machine systems. 2. The ballast bed fulfils important functions as the binding element between sleepers and substructure. 3. The loads of the trains having been distributed by the ballast bed onto the track substructure were not uniform. 4. The maintenance crew can perform this work highly efficiently using ballast bed cleaning machines. 5. Being very elastic, the ballast bed withstands the dynamic impacts. 6. The fouling having occurred under normal operational loads was caused by the broken off edges of the ballast stones, settlement of the stones and friction processes. 7. The increased proportion of fines reduces the elasticity of the track, the water permeability and the durability of the track geometry. 8.

TRACK RENEWAL AND TRACK REHABILITATION OPERATIONS Vocabulary. accuracy – точность arduous – трудный, тяжёлый careful handling – бережная транспортировка continuous assembly line – action – непрерывная конвейерная работа cost-efficiency – рентабельность, эффективность затрат cyclic action – цикличная работа expenditure – издержки, расходы double flange – двойная реборда колеса high output – высокая производительность hydrostatic drive – гидростатический привод by manual labour – вручную (to) pre-deposit – предварительно укладывать precise placement – точная укладка rear – задняя, хвостовая часть sleeper exchanger – шпалозаменяющая машина subsequent costs – последующие затраты track rehabilitation – реконструкция, ремонт железнодорожного пути track renewal – замена рельсового пути work area – рабочая зона The good functioning of the railway track depends upon the condition of the individual components such as rails and sleepers. Defective parts must be replaced in good time in order to avoid high subsequent costs. In the past, these material-intensive and arduous tasks were carried out by manual labour, but today these are performed using powerful machines. Mechanized track renewal methods help to reduce costs as well as to achieve high quality. The machines designed for track renewal operations allow conducting this work either in complex continuous assembly-line action or in compact cyclic action. Track rehabilitation using the continuous-action assembly-line method has proven to be the most cost-efficient method of work. The entire supply of new sleepers and rails within the track being laid is fully mechanized operation. Accuracy and high working speed are the outstanding features of this technique. Other advantages are the careful handling of the material, particularly the rails, and better preparation of the subsoil (sleeper bed). The new rails are pre-deposited next to the tracks. The new sleepers are supplied from the rear over the newly laid track. The absolutely accurate and automatic laying of the sleepers, as well as the installation of the new rails, goes like clockwork - in one shift of about four hours almost 1, 000 metres of track can be laid. Sometimes the application of cyclic track renewal method is much more reasonable. Laying track in cyclic method is an easy and compact single-sleeper laying process. The sleepers are pre-deposited between work area and sleeper transport wagon. Cyclic action single sleeper exchanger is capable to pick up and carry 20 concrete sleepers or 24 wooden sleepers at a time. Wheels are equipped with double flanges and hydrostatic drive. The machine can achieve the maximum self-propelled speed of up to 22 km/h. In the course of operation, the laying unit picks up sleepers with the help of two horizontally extending angle sections. Electronic measuring sensor for sleeper spacing is responsible for precise placement of sleepers. Sleepers are laid exact to the millimetre. The evident advantages of the modern cyclic action machines are simple electronic hydraulic sequence control, one-man-operation process, relative high output and cost-efficiency: 20 concrete sleepers are laid in 100 seconds. Answer the questions according to the text: 1. In what case and why is it necessary to conduct track renewal works? 2. Is the task of railway renewal a simple one? 3. Why have the mechanized track rehabilitation methods become popular? 4. What are the contemporary techniques for mechanized track rehabilitation operations? The machine types involved into each of them differ considerably, don’t they? 5. What are the advantages of continuous assembly-line track renewal method? 6. What are the operational features of continuous action track renewal machines? 7. When is the cyclic track renewal method preferred? 8.
