Inductive Control System For use on busy lines various safety devices are additionally available. One of these is the inductive train control. Each signal on a section of line equipped with this system has a device which activates the brakes of a passing train. The locomotive is provided with ”a transmitter” which has an iron-core coil and a condenser. This oscillating circuit is tuned to 2000 cycles/sec and is supplied with current from a high-frequency generator to which the coil of an electromagnet for a relay is connected. The high-frequency generator is driven by an electric motor or a small steam turbine which also drives a 24-volt direct-current dynamo. A second relay and two pilot lamps are connected to this dynamo. When the system is in operation, the high-frequency generator supplies current to the oscillating circuit of the locomotive and to the high-frequency relay, so that the armature of the latter is attracted by the electromagnet and allows current to flow through the 24-volt direct-current relay. When thus energized, the relay interrupts a flow of current to the actuating electromagnet of a valve. The signal beside the railway track is also equipped with an oscillating circuit tuned to 2000 cycles/sec. When the signal is at “safe”, its oscillating circuit is short-circuited and has no effect on the passing locomotive. However, if the signal is at “stop” and the train nevertheless fails to stop, the oscillating circuit of the signal will resonate in tune with that of the passing locomotive and withdraw so much energy from the latter circuit that the armature of the high-frequency relay is no longer sufficiently strongly attracted by the electromagnet and is therefore released. This in turn cuts off supply of current to the 24-volt relay, which then likewise releases its armature. This completes the electric circuit to the electromagnet that controls the monitoring valve. When this happens, the monitoring valve causes the brakes to be applied and the driving motor of the locomotive to be switched. At the same time, the pilot lamp “a” goes out and the lamp “b” lights up.

Ex. 11. Translate the following text from Russian into English. Do it in written form. Индукционная система автоматического управления торможением Indusi I 60 R гарантирует безопасное движение поездов. Она включает в себя путевое оборудование и бортовое оборудование. Путевое оборудование состоит из путевого индуктора (track magnet); бортовое оборудование содержит бортовой прибор, магнит и генератор, систему управления и дисплей. В определенных местах, например у сигналов или перед участками с ограничением скорости движения, оборудование Indusi I 60 R передает информацию с рельсового пути в кабину машиниста. Одно из многих преимуществ данного оборудования заключается в том, что оно надежно при любых климатических условиях.

Text B. Scan the text and write down all the unknown words. Read the text trying to guess the meaning of the unknown words. Retell the text in Russian.
A bullet train twisted down the track on autopilot after its driver left the cockpit (cab) to find his hat. The train, which can reach 167 mph, ran very-very slowly along on autopilot at 13-18 mph for about five minutes while its controls were unattended. Company rules at the Central Japan Railway require drivers to always wear their hats, but the driver “left the driver's seat to look for his hat after he realized he wasn't wearing it,” a spokesman said. Isn't there any sort of rule about leaving the cockpit while the train is running? There is now: “We have notified all drivers that they should continue driving until they reach a station, after which they should report that they have misplaced his or her hat.” (Reuters) .How reassuring for the passengers to learn that the drivers needed to be told that. Text С . Scan the text and write down all the unknown words. Read the text trying to guess the meaning of the unknown words. Retell the text in Russian.
Children's Railway For students of the children's railway school in Kratovo, in addition to math, history and literature the timetable this year also includes instruction on how to operate the fully working kids-sized train line, which runs from the school to the nearby village of Otdykh. The line is fully functioning complete with ticket offices, signals and three working stations: Pionerskaya, Shkolnaya and Yunost. The children are responsible for all aspects of the train's operations: "Controllers, conductors, drivers, switchmen, inspectors, cashiers these roles are all undertaken by the children," comments Svetlana Kovalenko, Press Officer for the Moscow Railroad. "Children study here for five years between the ages of 11 and 16. They have the opportunity to follow a variety of specialized subjects alongside the traditional curriculum. They are also introduced to responsibilities of work and they begin to understand how a railroad is run. "Attendance at the school is free of charge and we believe that it provides a valuable service to the children, many of whom come from underprivileged backgrounds. Lots of our students go on to follow higher or further education; this year around 50 of our students went on to study in higher educational institutions."
