    HOV means:

    • Hand-Operated Vehicle

    • Heavy Odor Vehicle

    • High Occupancy Vehicle

    • High Octane Volume

    Correct Answer
    A. High Occupancy Vehicle
    Explanation
    HOV stands for High Occupancy Vehicle. This term is commonly used to refer to vehicles that are designed to carry a certain number of passengers, typically more than one, in order to promote carpooling and reduce traffic congestion.

    What do you mean by CNG?

    • Compressed Natural Gas

    • Commuter Network Group

    • Clean New Garages

    • Crank Nexus Glue

    Correct Answer
    A. Compressed Natural Gas
    Explanation
    CNG stands for Compressed Natural Gas, which is a type of fuel that is used as an alternative to gasoline or diesel in vehicles. It is a cleaner and more environmentally friendly option, as it produces lower emissions compared to traditional fuels. CNG is made by compressing natural gas, mainly composed of methane, to less than 1% of its volume at standard atmospheric pressure. It is stored in specially designed cylinders in vehicles and can be used in both light-duty and heavy-duty vehicles. CNG is widely used in public transportation, commercial fleets, and personal vehicles as a sustainable and cost-effective fuel.

    CWR means:

    • Car Wait Region

    • Call When Ready

    • Continuous Welded Rail

    • Claim With Reason

    Correct Answer
    A. Continuous Welded Rail
    Explanation
    CWR stands for Continuous Welded Rail. This term refers to a method of constructing railway tracks where long sections of rail are welded together to form a continuous track. This technique eliminates the need for rail joints, resulting in a smoother and more durable track structure. Continuous Welded Rail is commonly used in modern railway systems to improve track stability, reduce maintenance requirements, and enhance train ride quality.

    Which of these is Articulated bus?

    • Long-Distance Trip Bus

    • Bus With Two Levels

    • Bus Which Bends In Middle

    • School Bus

    Correct Answer
    A. Bus Which Bends In Middle
    Explanation
    The correct answer is "Bus Which Bends In Middle." An articulated bus is a type of bus that is divided into two sections, connected by a flexible joint in the middle. This joint allows the bus to bend, making it easier to navigate around corners and maneuver through narrow streets. The bending feature of an articulated bus allows it to have a larger passenger capacity compared to a regular bus, making it suitable for high-capacity routes in urban areas.

    What can be used to make a Alternator?

    • Rotating Generator

    • Route Switcher

    • Bus Display Device

    • Inconsistent Commuter

    Correct Answer
    A. Rotating Generator
    Explanation
    A rotating generator can be used to make an alternator. Alternators are devices that convert mechanical energy into electrical energy. They consist of a rotating generator, which is a device that rotates to generate electricity. In an alternator, the rotating generator is connected to a mechanical source, such as an engine, and as it rotates, it produces alternating current (AC) electricity. This AC electricity can then be used to power various electrical devices. Therefore, a rotating generator is the correct answer as it is the necessary component to create an alternator.

    Main reservoir meaning

    • Train Station

    • Lead Engineer

    • Compressed Air Storage

    • Maintenance Garage

    Correct Answer
    A. Compressed Air Storage
    Explanation
    Compressed air storage refers to a system or facility that stores compressed air, which can be used for various purposes. It is commonly used in industries and manufacturing processes to power pneumatic tools and equipment. The compressed air is stored in tanks or reservoirs, allowing it to be readily available when needed. This storage system ensures a constant supply of compressed air, enabling efficient and reliable operation of pneumatic systems.

    Lineside signals means:

    • Engine Power Indicator

    • Passenger Counter

    • Fuel Gauge

    • External Visual Signals

    Correct Answer
    A. External Visual Signals
    Explanation
    Lineside signals refer to the external visual signals that are placed alongside the railway tracks. These signals are used to convey important information to train drivers, such as whether to proceed, slow down, or stop. They help ensure safe and efficient train operations by providing clear instructions and warnings to the train crew about the track conditions ahead.

    Layover time meaning

    • Time Of Departure

    • Time Of Arrival

    • Scheduled Downtime

    • Unexpected Maintenance

    Correct Answer
    A. Scheduled Downtime
    Explanation
    Layover time refers to the period of time between the arrival of one transportation vehicle and the departure of another. During this time, the vehicle is not in operation and is typically used for maintenance, refueling, or other scheduled activities. Therefore, the correct answer "Scheduled Downtime" accurately describes the meaning of layover time.

    Meaning of term Bus shelter

    • Bus Repair Shop

    • Section Of Road For Buses

    • Parking Garage For Buses

    • Bus Tunnel

    Correct Answer
    A. Parking Garage For Buses
    Explanation
    A bus shelter refers to a structure or area specifically designed to provide shelter and waiting space for bus passengers. It typically consists of a roof, seating, and sometimes walls or glass panels to protect people from weather conditions. However, a parking garage for buses is a completely different concept. It is a designated facility where buses are parked when not in use or undergoing maintenance. It is a secure and organized space that allows for the storage and maintenance of multiple buses simultaneously.

    Do you know the meaning of Holding lights?

    • Signal To Change Drivers

    • Signal To Stop Train

    • Signal Not To Move Train

    • Signal To Move Carefully

    Correct Answer
    A. Signal Not To Move Train
    Explanation
    Holding lights are used in railway signaling to indicate that a train should not move. When the holding lights are displayed, it means that the train should remain stationary until further instructions are given. This signal is important to ensure the safety and coordination of train movements on the tracks.

    Which of the following is the part of the Boss?

    • Speed-Controlling Device

    • Fare Collector

    • Center Portion Of Wheel

    • Air Quality Measurement

    Correct Answer
    A. Center Portion Of Wheel
    Explanation
    The center portion of the wheel is a crucial component of the boss. The boss is the central part of a wheel where the axle is attached. It provides support and stability to the wheel, allowing it to rotate smoothly. The other options listed, such as the speed-controlling device, fare collector, and air quality measurement, are unrelated to the boss of a wheel.

    An Auto Restricted Zone (ARZ) refers to a designated area where certain restrictions and regulations are automatically enforced. This could include limitations on vehicle access, speed limits, or specific driving behaviors. The term "auto" suggests that these restrictions are implemented automatically, without the need for manual intervention. This concept is commonly used in traffic management systems or areas with high security requirements to ensure compliance and enhance safety.
