    Description
    Loco drivers of heavy haul trains must be aware of relatively complex train dynamics.  They need to have a broad understanding of the Loco operation and the various control systems that make the loco a safe operating machine.  Loco drivers should also have an understanding of engine defects that many occur enroute and have the capability to trouble shoot them and take corrective / remedial action.

    The Diesel Loco Simulator is designed to satisfy these objectives.  The trainer consists of a Driver Panel and Control Panel similar to that in the WDG 3A Loco.  The panel consists of instruments to indicate various engine parameters.  The engine is simulated using an AC or DC Motor.  This is coupled to a scaled down working alternator.

    Scaled down electric motors are used to simulate traction motor.  Six such motors are used each motor is fitted with speed sensors.

    A PC based system is used in place of the loco microprocessor.  However a simulated version of the microprocessor will indicate a display similar to the loco microprocessor.  All text messages will be indicated on this panel.  The PC based system is used in order to build a training system with specific lesson plans.  Some of the faults that can be generated are as follows:

    • Low lube oil pressure during run in locomotive
    • Lube oil pressure not building up
    • Fuel oil pressure not building up
    • Fuel oil pressure has become zero during run suddenly
    • Fuel oil pressure fluctuating
    • Fuel oil pressure dropping on load
    • Hot engine alarm coming up
    • Loco shutting down with hot engine indication
    • BP pressure not building up

     

    • Loco Brake not applying
    • Loco Brake not releasing
    • Fuel pressure not building up
    • Engine not cranking
    • Engine cranking but not starting
    • Engine become over speed during cranking
    • Engine starting but not raising
    • Loco working only in one direction
    • Continuous wheel slip indication coming
    • Hot engine alarm coming
    • Battery charging meter showing discharging

    Battery charging meter showing over charging

    The simulated microprocessor control shall include following features :

    • The simulator shall be required to demonstrate the functions as on the actual locomotive.
    • Simulated Sensing and implementation of master controller settings.
    • Transition from Series to Parallel Based on the Speeds
    • Control of auxiliaries, including radiator fan temperature settings.
    • Motoring Operation from N1 to N8
    • Dynamic Braking Operations on setup, half and full DB positions.
    • Wheel Slip Relay and indication
    • Speed control through Notch Handle & Independently
    • Pneumatic Brake application and reduction of speed.
    • Traction Horse Power increase and decrease
    • Battery Charging and Load control
    • Fault Logging and Resetting on the Microprocessor
    • VCD Activation and De-activation by the Microprocessor
    • Automatic Flasher Light Activation.
    • Altitude & Atmospheric temperature based Load control by Microprocessor
    • The Reverser Direction indicating the actual movement should be shown through indicators
    • Control the speeds of Radiator fan and HOT engine indications with appropriate corrections as on actual locomotive.
    • Low water Level Indication
    • Engine Over-speed Protection
    • Battery Discharge indication on Microprocessor & Provision to disconnect the batteries from the simulator circuit.

    Simulated Sensor signals for sensing and indication as on actual microprocessor locomotive will be provided i.e. Lube Oil Temp, Lube Oil Pr, Engine Water Temp, Engine Speed, Traction Motor Speed and Current, Battery Charging Current, Auxiliary Generator Field and Armature, Exciter Field and Armature, Barometric Pressure, Atmospheric Pressure Compressor Cutting In and Cutting Out, Fuel Oil Pressure

    The Simulator will facilitate demonstration of individual wheel speed and thereby check the wheel slip / slide condition and take corrective measures to reduce the speed or activate sanding operations.

    The driver panel is fitted with the flasher lights to simulate abnormal conditions on the track automated alerter system or VCD operation and automated brake operation demonstrated.


     

    The panel also demonstrates the self test at power ON or on request of the driver.

    The microprocessor control panel and driver panel are in a simulated closed loop where by the following systems cab be controlled

    • Fuel Oil System
    • Lube Oil System
    • IRAB1 air brake system
    • Engine Cooling Water System
    • Instructional Manual
