What is the primary function of a Train Control Apparatus on a train?

To manage fuel consumption
To receive and display cab signals and control train speed
To communicate with passengers during transit
To monitor weather conditions along the route

The correct answer is: To receive and display cab signals and control train speed

The primary function of a Train Control Apparatus is to receive and display cab signals while controlling train speed. This is crucial for maintaining safe operations on the railway. The apparatus ensures that train operators have real-time information about track conditions and speed regulations, which directly affects the safe and efficient movement of trains. By receiving cab signals, the system informs the conductor about aspects such as stop signals, speed restrictions, and track status, enabling timely decisions to be made. Control of train speed is essential for not only adhering to regulations but also for ensuring passenger safety and comfort during the journey. The other options, while related to train operations, do not accurately describe the primary function of the Train Control Apparatus. Fuel consumption management, passenger communication, and weather monitoring are important aspects of train operation but are not the central role of the Train Control Apparatus itself.
