Must know: kinetic, electrical diagrams and arrangement of serviced equipment and installations of passenger cars of all types; specifications individual parts and assemblies, installations and devices of cars; rules, technical instructions, instructions of manufacturers, tolerances and wear rates allowed during the operation and repair of parts and assemblies of cars; device and design of control and measuring instruments, fixtures and tools used in the maintenance, repair and testing of passenger car units and the rules for using them; fundamentals of electrical engineering and mechanics; order technical training wagons of the train in flight, acceptance and delivery of the train; ways to identify, prevent and eliminate malfunctions in the operation of parts and assemblies of cars; technology of maintenance and control of the technical condition of cars and their equipment; location of points Maintenance and equipment of wagons along the route passenger train; timetable for passenger trains; traffic safety instructions and measures fire safety passenger trains. During maintenance on the route of passenger trains, consisting of cars with electric heating or air conditioning - 6th category.

After the train is sent on a flight from the passenger station, the point of formation or turnover, the train electrician (TEM) controls the operation of the electrical equipment:

• checks the serviceability of the tail signal lights on the tail car;
• examines the electrical equipment inside the car and on the outside of the panels and control panels;
• writes down the readings of electrical measuring instruments in the trip sheet;
• checks the operation of the circuits of electricity consumers, the heating alarm of roller axle boxes and fire alarm installations;
• checks the state of insulation of electrical equipment by signaling a short circuit to the case;
• controls the operation of high voltage electrical equipment;
• conducts additional briefing of wagon conductors on the specifics of operating a particular type of wagon directly at the conductor's workplace.

After 3-4 hours of movement of a passenger train from the point of formation or turnover, the electrician must check the readings of electrical measuring instruments and record in the trip sheet of the electrician the current of the battery charge, its voltage, the voltage of the generator and the lighting network of each passenger car of the train. Control over the operation of the electric equipment of cars with a recording of the readings of electrical measuring instruments is carried out along the route at least three times a day.

When the fuse in the circuit of the generator, battery or any consumer is triggered, the electrician identifies the cause of the trip, eliminates it, replaces the fuse fuse and checks the operation of the car's electrical equipment. If failures along the way cannot be eliminated, at the nearest train stop, electricity consumers switch to power supply from the neighboring serviceable car. When switching to the power supply of a passenger car (no more than one) from a serviceable neighboring car, the electrician must first make sure that the electrical equipment of the car from which it is supposed to take electricity is in full working order.

In the absence of positive current leaks to the body in both cars, connect the inter-car connections and turn on the package switches on the boards or consoles of both cars, respectively "Supply to the main" and "Reception from the main". After that, for at least 15 minutes, the operation of the electrical equipment of both cars should be continuously monitored. The transfer of electricity consumer circuits to power from another passenger car is drawn up by an act of any form signed by the head of the train, the electrician, the conductor of the emergency and serviceable car.

On wagons without an emergency lighting main, in the event of a power supply system failure and the impossibility of restoring its operability, the electrician informs the head of the train about this. If a blown fuse is found in the excitation winding circuit of the DC generator, it is allowed to remove the seal at the car stops, open the casing of the carbon voltage regulator and replace the fuse, which must be documented in the FMU-73 form signed by the head and the electrician of the train. When the fuse in the excitation winding circuit of the generator blows again, the consumers are fed from a serviceable passenger car. The operated current protection device in the circuit of any consumer of electricity is restored by the electrician after checking the circuit. Found defects are eliminated. In the event of repeated operation of the current protection device, the circuit of electricity consumers is disconnected from the power supply system until the cause of the failure at the point of formation or turnover is clarified. The operability of electric power consumer circuits is checked while the car is in motion by turning them on from the control panel of the car’s electrical equipment and monitoring the readings of electrical measuring instruments and alarms.

The electrician participates in the inspection of the undercarriage equipment carried out by the employees of the maintenance points. At intermediate stations, an electrician finds out the causes of extraneous noises or knocks that occur during train movement, checks the generator mount, generator drive, boxes with electrical equipment, the condition of terminal boxes, cables, detachable connections, fastening of temperature sensors on axle boxes, battery box deflectors. Upon detection of failures of the equipment located under the car, or the unsatisfactory condition of its safety devices, the electrician:

• takes measures to ensure traffic safety by the train brigade or together with the workers of the PTO;
• when the indications of the system for monitoring the short circuit of wires to the body of the car indicate a decrease in the insulation resistance in the electrical circuits of the car, the electrician at the stops must identify circuits with reduced insulation resistance and places of insulation failure in them. If it is impossible to identify the reason for the decrease in the insulation resistance of the electrical circuit during the flight, the circuit is turned off.

In a high-speed train, when the axle box heating control system (SKNB) is triggered or if another malfunction of the car is detected that threatens the safety of train traffic and the lives of passengers, the electrician must immediately inform the head of the train, who, by radio, transmits to the locomotive driver a message about the need to immediately stop the train. If it is not possible to transmit such a message to the locomotive driver, the train must be stopped by a stop crane.

In all cases, if the axle box heating control system fails, the electrician instructs the conductors of the cars at train stops to check the heating of the axle boxes in accordance with the Instructions for the conductor of passenger cars.

In the event of a train stop after the activation of the axle box heating control system, the electrician and the head of the train must personally check the temperature of the axle boxes by touch.

With significant heating of the axle box, the electrician, the head of the train and the locomotive driver set a safe mode of movement to the nearest station or maintenance station, where the wheel pair is rolled out from under the car for a complete revision of the axle boxes in order to determine the cause of heating.

If the temperature sensor fails (breakage of the SKNB), it is allowed to move the car to the nearest PTO with one temporarily shunted temperature sensor.

If the circuit of any fire sensor fails at night (the control unit signals a fire or a malfunction), it is allowed to temporarily operate the unit with the acoustic alarm turned off until daylight, and if it is impossible to establish and eliminate the cause of the sensor circuit failure during daylight hours - to the point of formation or turnover. In this case, it is necessary to systematically check the premises and the condition of the equipment at the location of the failed fire detector.

In all these cases, an act of the form FMU-73 is drawn up in two copies signed by the head of the train, the electrician and the conductor of the car.

When checking the operation of electrical equipment, the main batch switch of the power supply system must not be set to the zero position, since the roller box heating control systems, the fire alarm installation, the automation circuits, and the alarm are turned off in this case.

In the event of a fire or a fire in passenger car the electrician must act in accordance with the Instructions for ensuring fire safety in the cars of passenger trains and, together with the head of the train, take part in the evacuation of passengers and extinguishing the fire.

On the way of the train, when inspecting train sets, changing locomotives, as well as at the turnaround and formation point, the electrician, together with the locomotive crew or employees of these points, connects high-voltage connections to the locomotive. When the train is placed under electric heating at the station from a stationary high-voltage power supply point, the electrician connects and disconnects the high-voltage line in accordance with local instructions.

In the event of a malfunction of electrical equipment that cannot be eliminated along the way, the electrician, through the head of the train, must submit an application for repairs at the depot (on the section) of the turnover point or formation.

In the event that PTO employees at intermediate stations or turnover points detect malfunctions that require replacement of wheel sets or dismantling of the gear-cardan drive, an act FMU-73 is drawn up indicating the malfunction, while it is prohibited:

• use non-standard fuse-links, install fuse-links in fuses that do not correspond to the nominal values ​​​​of the protected circuit;
• work with the equipment located under the car on an unguarded train;
• lay temporary cables (wires) both inside the car and from car to car.

Upon arrival at the turnover point, the electrician is obliged to identify the cause of the malfunction that occurred along the route, make an appropriate entry in the trip sheet and the VU-8 form log about the elimination of the malfunction.

For wagon malfunctions that the electrician could not eliminate on his own, an application must be submitted to the PTO of the passenger turnover station.

A copy of the application, which remains with the head of the train, must be signed by the person who accepted the application for repairs. The electrician, together with the workers of the PTO, takes part in troubleshooting.

After completing the application repair, the electrician must check the quality of the work performed and report to the head of the train about the readiness of the train for further movement. Upon the return of the passenger train to the point of formation, the electrician is obliged to hand over the composition to the foreman or senior inspector of the relevant repair departments, and also to transfer the application for repair to the employees responsible for preparing passenger cars for the flight.
