NEW DYNAMOMETER-CUM-RESEARCH CAR OF INDIAN RAILWAYS

A rather detailed description is given of a car for testing new classes of locomotives to determine their power characteristics. The Research, Designs and Standards Organization (RDSO), Ministry of Railways, Lucknow, undertook to design, develop and manufacture the car using local expertise available in the organization. Only the essential items of instrumentation have been imported. It is claimed that the scope of testing with this car is much wider than that with the conventional dynamometer cars available for import. Electronic/electrical transducers and recorders of digital as well as analog types are used for the measurement, computation, logging and recording of various quantities. The main parameters that are to be measured and recorded during tests with the new car include drawbar pull, speed, distance traveled, time, horsepower, work done, acceleration of the train, fuel/energy consumption of the locomotive, voltages, currents, frequency, power factor, energy consumption, temperatures, vibrations, stresses, pressures, deflections, etc. For certain instruments, radio telemetry is provided; for others, closed-circuit TV.
