"Automating the railways".

At present control of the high-speed trains is semi-automatic since they are automatically forced to comply with permissible speeds at any instant. Stops at station platforms are under the driver's control. The whole line in Japan, for example, is directly controlled from Tokyo and for this purpose is divided into four systems. The state of the line is continuously surveyed and information is transmitted at high speed to the control centre. Each train automatically identifies itself by generating a unique frequency as it passes fixed ground equipment and the information is displayed on the control system at Tokyo. Trains entering stations automatically set the points system according to classification, i.e. whether super express, limited express or freight. One interesting but simple safety feature is provided to enable anyone on the line to stop the train in an emergency. It consists of push-button switches placed at intervals of 50 m. Operation of the switch shorts the track circuit, and consequent indication in the driving cab of an approaching train causes the brakes to be applied automatically when at an appropriate distance from the danger position. All the safety circuits are fail-safe, and the possibility of an accident due to human fallibility has been virtually eliminated. Current developments intended for future installation would incline programmed control, obstacle defection by a guided radar, controlled braking to a prescribed point and centralized computer control. Extensive work is under way in our country to utilize television technique in industry, science and agriculture. Some years ago one of the research institutes of our country designed television apparatus which is now used in railway transport to record the serial numbers of freight cars arriving at a station. As a train pulls in at a station, somewhere at a distance of ten kilometers an operator sees this train on the screen of his television set. The operator reads aloud the serial number of the freight cars and they are recorded by a type recorder. On another television set the operator can see all the railway lines in a station. The operator only has to press a button and another station will appear on the screen. These installations are being used in connection with the shifting of freight cars.

The Central Research Institute of the Military of Railways is designing a new television apparatus which will enable engine drivers “ to see” the condition of the freight car even when it is dark.

«Carriages and wagons”

The cars used on the early railways were very much like the stage-coaches and wagons traveling on ordinary roads. Although drawn by horses, these vehicles had flanged wheels which kept them on the rails.

At time went on an railroads had to carry more and more freight, bigger and better cars were invented for hauling different kinds of goods. Today, the railroads have several classes of freight cars, there being many varieties in each class.

The box car is considered to be the most common type of covered car. It is a general-all purpose car intended to carry all kinds of ordinary goods which must be protected from the weather. A special type of b ox car is a refrigerator car used for hauling food products. The walls, floor and roof of this wagon are air- and waterproof to protect goods from the heat of the outside air.

Another type of car is a tank car intended for liquid goods. The long cylindrical tank of the car is filled through an opening on the top and emptied through a special device in the bottom.

Coal, ore, gravel, and other similar goods are known to be conveyed in open-top cars, the principal types of these being the gondola and hopper car. Both types are designed for mechanized loading and unloading and, therefore, built especially strong and durable.

The simplest type of car is the flat car. Being usually employed for transporting rails, beams, timber, and heavy machines, they, if fitted with special devices, can also carry containers. The container traffic is now coming into wide use on all modes of transport because it reduces the cost of loading and unloading goods and decreases the danger of their breakage. The fact is that goods are packed into containers at factories or ware houses and are not disturbed while in transit, thus being conveyed from “ door-to-door”.

We know the passenger rolling stock of today to comprise several types of cars. There exist sleeping and dining cars, coaches for day and night sendee, saloon coaches for tourists, etc. The modern rolling stock is built with two types of inside arrangement. One is the compartment type with a side corridor, and the other is the open vehicle with a central passage.

"Movement of freight traffic"

Movement of freight starts at the initial terminal where the train is made up in the classification yard. Here cars are collected in groups or blocks. These are assembled on a departure track. The number of cars assigned to a train is related as nearly as possible to the tonnage capacity of the locomotive. After assembling the various blocks of cars on the track from which the train is to leave, they are coupled up with air brake connection, then tested and inspected. Defective cars are quickly repaired; if this requires more time than is available such cars are cut out and dispatched in a later train. The engine crew boards the train at the locomotive terminal. They pick up the caboose with the train and attach it to the rear end of the train, or a yard engine may handle the caboose. Prior to leaving the yard terminal office the freight conductor receives a series of sheets called billing, which show the number, character and destination of each car in his train, and checks the train for correct make-up or” consist”. When the train is ready to move, a signal from the conductor to the engineer starts it on its way. Except for stops for water or fuel a through freight train will run normally to the next intermediate terminal without stop or change in its consist. The

conductor makes out what is called a wheel report, listing the initials and numbers of each car,weight of the car, weight of lading and the points between which the train moves it. These wheel reports are the records from which the car accountant keeps track of car movement and the statistical department of the railroad compiles freight train and traffic statistics. At intermediate terminals cars consigned to destinations within the particular territory are cut out of the train New cars at intermediate terminals may be added. The train progresses by successive stops through other intermediate terminals to final destination, where it moves to the terminal yard. At the point cars are classified for delivery to the various industries, the operation being carried out by local yard crew.

“ The diesel traction”

The advance of transportation took a long time and scores of talented engineers did all in their power to develop the transportation system people have now at their disposal. But man never stops at what he had reached, and what seems fantastic today turns out to be quite realizable tomorrow.

The idea of creating a new kind of motive power for locomotives interested Russian scientists and engineers long ago. Great contribution to the solution of this problem was made by the Higher Technical School in Moscow later named after N.E.Bauman. Thus Prof. Grenetevsky designed an original diesel engine to meet the requirements of railway sendee while A.N.Shelest proposed a project of an original diesel locomotive and patented it in Russia and England. Nevertheless, in pre-revolutionary Russia these as well as many other projects were not realized.

The transport difficulties in the early twenties made railway engineers turn their attention to diesel traction. As a result, large-scale research and experimental work was done despite the great economic difficulties the young Soviet Republic faced at that period.

We may consider November 6, 1924 to be the birthday of the world's first main-line diesel-electric locomotive. This, 1,000 hp unit was built to Prof. Gakkel's design. Field tests showed the task of creating a practical main-line locomotive had been largely solved.

The diesel locomotive is more expensive to build and maintain than the electric of equal power since the diesel locomotive carries a power plant on itself. In addition, the diesel engine is an air pollutant prime mover, so the diesel traction should not be recommended for use on suburban lines round large cities. Noise and vibration are also considered the drawbacks of the diesel locomotive. Another disadvantage of the diesel locomotive is that the diesel engine runs on organic fuel the supplies of which are not inexhaustible.

Diesel traction is normally employed today on non-electrified trunk lines and on lines where traffic is not dense enough to justify electrification. I addition, it is the diesel traction which is particularly suitable for switching services for the diesel locomotive is not connected to the overhead wires and can easily and rapidly perform its switching duties.

"From the history of railway construction in Russia".

Our country, Russia, stretches across two continents, from the Baltic Sea to the Pacific Ocean. The first railway in Russia using steam traction was an industrial line at Nizhni Tagil in the Urals, built in 1834, for which the first two steam locomotives in the country were constructed by father and son named Cherepanovs. The first public railway was the Petersburg-Pavlovsk railway. At first it was opened from Pavlovsk to Tsarskoye Selo with horse traction in October, 1836. Locomotives were introduced in 1837. The first important railway construction from Petersburg to Moscow was begun in 1843 and opened to public traffic in 1851. That was a first -class double-track railway line, which linked two large industrial and cultural centres. It had 644 km in length, 185 bridges and 19 viaducts were erected to make the line as straight and level as possible. Since 1890 to 1900 more than 11,000 miles of railway were built. By the end of 1925 the railway system had grown to 46,300 miles. The Baikal-Amur Line, more than 3,000 km long, was built in the Far East of our country, and the process of building new railway lines is going on. Today railway transport different than that in old times. There are many thousands of locomotives is quite different than that in old times. There are many thousands of locomotives, hundreds of thousands of cars and oil-cisterns. The trains today go much faster. The whole wagon fleet was fitted with continuous brakes, and hundreds of thousands wagons were equipped with automatic couplings. Many old lines were improved and electrified and use of diesel traction was begun. Heavy rails were laid extensively and a substantial mileage was equipped with automatic block signaling. Railway transport is still one of the cheapest ways hauling freight over long distances. Communications are important to the national economy of a country. Without good roads and railways a country cannot develop its resources and industry. Without roads it is impossible to market agricultural produce.

"Assembling the train. Movement of passenger traffic."

Passenger trains are assembled in a car yard with a number of specified cars as baggage, mail and express coaches, dining, parlour and sleeping cars. Every car in the train has received careful inspection inside and outside to make certain of its mechanical condition. Each car has been washed: not only have inside woodwork and floors been scrubbed, but carpets and seats have been gone over with vacuum cleaners. Preparations for dining service constitute a considerable operation. Food supplies have been requisitioned from the store rooms, and stored in the car refrigerators, cupboards and small but complete pantry. Clean linen has been stocked. After preparing the cars and cleaning and stocking them with supplies, they are coupled, inspected, and tested to ascertain whether mechanical appliances such as air brakes and signal and steam lines are functioning properly. The train is now ready to receive its passengers, baggage and mail.

When ready, a switching engine moves the trains to the assigned departure track at the station. The road locomotive has been inspected. The crew takes over the locomotive at the terminal, moves in to the departure track and couples it to the train. Here the train receives tests of air brakes and signal lines again. The train crew has been mobilized, they are called for duty according to schedule. A modern train stands in the terminal ready to receive its passengers. It departs at the moment called for by its schedule. The program of departure seems so simple that few passengers realize that it has required the services of a small army of railroad employees to make the movement possible.

“ Signal and signaling”

Safe operation of freight and passenger trains requires a system of signaling. To inform the locomotive and train crew of the position of other trains in relation to their own, signals installed at frequent intervals give indications which are visible both by day and by night. Wayside signals installed along railroad tracks are called fixed signals.

We know that the semaphore used to be the most common type of the signal. The relative position of the semaphore arm constituted the signal. To indicate “stop” a horizontal arm was used. “Proceed” was indicated by a vertical arm. To give restrictive (i.e.cautionary) indications the arm was inclined up or down. Colored lights give the indications at night. The semaphore mechanism is equipped with lenses illuminated by a lamp, so that a red light shows when the semaphore is in the “stop” position, a green light – when the semaphore is in the “proceed” position, and a yellow light – when the semaphore is in the restrictive position. The colour-light signal sometimes used is known to have semaphore arm and give both day and night indications be means of red, green and yellow lights. We know some signals to be operated by hand, others to be automatic. Locomotives on some railroads are known to be equipped with apparatus located in the cab, which gives a continuous indication to the engine man identical with that that shown by wayside signals.

By cab signals the engine grew is supposed to be always informed of conditions ahead regardless of the weather that affects the man's ability to see wayside signals. Locomotive cab signals are equipped to give audible warnings whenever the aspect changes to one more restrictive. A protective device is installed on some railroads to apply the brakes automatically and bring a train to a stop if, for any reason, a “stop” signal should be passed. It is called automatic train control. The first signals installed are known to have been hand-operated, usually by station employees.

4. Where is the alternating current converted into direct current?
5. What is the essential part of any substation?
6. What is a rectifier of a substation needed for?

Nowadays technical progress, including the progress in railway engineering is unthinkable without the proper power supply system.

Till recent years, all electric energy has been generated by thermal and hydro-power stations. But the hydro-power stations are always tied to rivers. As for the thermal power plants the supplies of fuel needed for their operation are not inexhaustible. So power engineers are now in search of new sources of energy.

The great efforts of scientists and engineers have resulted in discovering atomic energy which caused a revolution in energetics.

After having been generated, the electric energy is sent to the electricity grid system of the country. It is the grid system that distributes the power to the consumers, including the electrified railways.

Both conventional and nuclear power stations generate a high voltage alternating current(a.c.).The fact is that the alternating current can be more economically transmitted over long distances than the dirrect currnt(d.c.) and the higher the voltage the less energy is lost.

Although the alternating current can be used to drive trains, in many countries it is converted to the direct current because d.c. Motors are simpler in construction than a.c. machines.

As is known, the conversion of a.c. to d.c. takes place in railway substations. The first essential of a substation is a trandformer in which the electric current taken from the transmission line is lowered in voltage. Another important instrument the substation is fitted with is a rectifier which converts a.c. to d.c, this one-way (i.e. dirrect) current being then fed to the overhead wire.

Electronics has found a wide application in railway substations, silicon rectifiers being one of the most commonly used electronic instruments. Due to electronics most substations are now operated by remote control.

“ Engine driver today.”

Nowadays in Russia modern diesel locomotives are known to have a lot of highly complicated machinery which must be regularly examined if the reliability of locomotives and safety of passengers and freight are to be maintained. At present, diesel locomotives are reported to handle about 50 per cent of the transportation. The passenger diesel such as “TEP-70” and “TEP-80” can run at a speed of 160-200 km/h, and freight diesel such as “2TE-116” can handle 8,000 ton trains and more, the power of their diesel-generator equipment reaching 6,000hp. Therefore the railways need highly qualified engineers and drivers to operate diesels successfully. The work of a modern diesel locomotive driver completely differs from that of a steam locomotive driver. The modern driver sits comfortably in an upholstered chair in a very clean cab. Right in front of of of him he has a large glass window which gives him a splendid view of the line ahead. In wet or snowy weather, a powerful screen wiper keeps the glass clean. Besides that, there are special fans to prevent window glass from freezing in cold winter. All the information the driver requires, i.e., speed, pressure, engine temperature, etc., is given by a few dials and warning lights on an instrument panel in front of him. The driver's control cab which is made as sound-proof as possible is constructed of a thin iron sheet lined with wooden panels on the inside. The side windows of the cab for the driver and his assistant are made to slide, and the others are of the drop type as those used in carriages.

And now let's learn how to train the future diesel and electric locomotive drivers in England. Traditional training for train drivers is expensive both in terms of cost and time. It costs 40,000 English pounds to provide basic training for one driver and takes up to 11 months. Theoretical training is easy to organize and typically one instructor can cope with up to 12 trainees (ученики). But train drivers require considerable practical instruction to acquire the necessary skills which drivers need for competent performance. Practical training requires minimum 300 hours on service trains with an instructor. Such training provides experience of normal everyday driving duties. However, it is almost impossible to provide experience of unusual and emergency situations. Most practical training is carried out initially in a depot using old rolling stock to provide training in shunting and mainline driving. It is in this area of training that simulation can be most effectively used. There are many problems that require attention of both railway managers and trainers if simulation is to be successfully introduced and integrated into an existing training system.
