The term "rolling stock" refers to the vehicles used in a transit system. These vehicles can include buses, trains, trams, or any other form of transportation used to move passengers or goods. It does not specifically refer to wheels, empty vehicles, or passengers, but rather encompasses all types of vehicles used within a transit system.

Gangway refers to a passageway or aisle that allows people to move between train cars. It is commonly used in cross-train car access, where passengers can walk from one carriage to another while the train is in motion. This term is not related to train rails, subway platforms, or bridges of boats.

Alight means to exit a transit vehicle.

A stinger is a power supply lead used to connect electrical devices to a power source. It typically has a plug on one end that can be inserted into an electrical outlet, and on the other end, it has connectors or terminals that can be attached to the device that needs power. This allows the device to receive the necessary electrical current to function properly.

The Crush load refers to the maximum number of people that a transportation system or vehicle can safely carry. Therefore, the correct answer is "Maximum Person Capacity" as it directly relates to the concept of Crush load.

A graded section of rail refers to a sloping or inclined portion of a railway track. This term is commonly used in the railroad industry to describe a section of track that is built on a slope or incline. This answer is correct because the other options - reduce speed, form of liquified gas, and pick up passengers - do not pertain to a bank or a section of rail.

The word "alee" refers to a nautical term used to describe the side or direction that is sheltered or protected from the wind. It is often used to indicate the opposite side or direction from where the wind is blowing. In this context, "away from wind direction" is the correct answer as it accurately defines the meaning of the word "alee".

The correct answer is "Weight Of Empty Vehicle". Tare weight refers to the weight of a vehicle when it is empty, without any additional load or passengers. It is the weight of the vehicle itself, excluding any fuel, passengers, or the driver. This measurement is important for various purposes, such as determining the maximum load capacity of the vehicle or calculating the net weight of goods being transported.

The correct answer is "Uncrewed Railway." This refers to a railway system that operates without a crew on board the trains. It is automated and controlled remotely, eliminating the need for human operators. This technology is often used in modern metro systems and can improve efficiency and safety by reducing the risk of human error.

The correct answer is "Boat's Propeller." A screw is a device used to convert rotational motion into linear motion. In the context of a boat, the propeller acts as a screw by rotating and propelling the boat forward through the water. It works by creating a pressure difference between the front and back of the blades, which generates thrust and moves the boat.

A lamp iron refers to a light mounting bracket that is used to securely attach a lamp or light fixture to a wall or ceiling. It provides support and stability for the light, ensuring that it is securely fixed in place. This bracket is typically made of iron or another sturdy material to withstand the weight of the light and prevent it from falling or becoming damaged.

Transfer means having the privilege to change vehicles. This could refer to situations where a person is allowed to switch from one vehicle to another, such as in a car rental service or a transportation system with multiple modes of transport. It implies the ability to transfer from one vehicle to another without any restrictions or additional charges.

The correct answer is "Enter Transit Vehicle." The word "board" refers to the action of entering a transit vehicle, such as a bus, train, or plane. When someone is told to "board" a vehicle, it means they should enter it and take their seat or find a place to stand. Therefore, "Enter Transit Vehicle" is the most appropriate meaning of the word "board" among the given options.

The correct answer is "Emergency Brake Valve." EBV stands for Emergency Brake Valve, which is a device in a vehicle's braking system that controls the application of the emergency brakes. It is responsible for activating the emergency brakes in case of an emergency or when the driver manually applies the emergency brake.

The correct answer is "Open Door Indicator." This is because an open door indicator is a device or signal that alerts passengers or operators when a door is open. It is important for safety and security reasons to ensure that doors are properly closed before a train starts or moves.
