The correct sequence is: Air compressor generates compressed air → stored in reservoir → regulated through control valve → transmitted to brake cylinders on wheels.

Cant or superelevation is the banking of the outer rail on curves to counteract centrifugal force and allow trains to maintain higher speeds safely.

Standard Indian railway concrete sleepers are typically 200-250 mm thick to provide adequate support and distribution of train loads.

Creep refers to the slow longitudinal movement of rails caused by train movements, thermal stress, and environmental factors.

Screw couplings were used in older Indian railways to manually connect coaches together, though they have been largely replaced by automatic couplers.

A yellow signal indicates 'caution' - the driver should prepare to stop at the next signal as it may show 'stop' indication.

For a curve radius of 400 meters, the maximum safe speed is approximately 60 km/h to prevent derailment due to centrifugal forces.

Regulating engine temperature is the function of the cooling system, not the fuel injection system. The fuel injection system focuses on fuel atomization and precise timing.

Block sections in Indian Railways typically range from 5-10 km, which is the distance between consecutive signal posts for safety purposes.

Gati Shakti is a national master plan to develop integrated multimodal infrastructure for economic growth and faster movement of goods and passengers.
