Sleepers, many of the sleepers on modern track are being replaced with concrete sleepers.
No. Railway tracks are only the rails and ties/sleepers and hardware used to hold the track in place. A railway line is a set of tracks designed to move a train between at least 2 points. A railway line can consist of many tracks.

how to replace railway sleepers

The wooden or concrete railway sleeper (or railroad tie) is used as the base for the railway track to keep the tracks intact in its place In other words, wooden sleepers hold the rails to the correct gauge. Additionally, they absorb and distribute the weight of the train uniformly. swampesterswithin.blogspot.com
To keep the rails at a certain spacing, and to spread the weight of the train over a wider area.
The width apart of rail tracks are set to the gauge of the trains and carriages that are allowed to run on those tracks. They are kept in position by wooden sleepers, though concrete sleepers are often used nowadays.
Railway tracks are laid on large sleepers (also known as ties) to distribute the weight of the train and its cargo evenly across the ground, providing stability and preventing the tracks from sinking into the soil. The sleepers also support and anchor the rails, ensuring that they remain aligned and in place, even under the stress of heavy loads and moving trains.
The large surface spreads the weight of the train (and tracks) over a broader area. The shape of the sleepers also helps to keep them firmly in place while trains are running on the tracks.
Railway lines (tracks) are laid down on a bed of evenly spaced sleeps. The sleepers are usually of creosoted heavy timber, though concrete is often used instead of wood. The sleepers kept the rail tracks from moving and causing a train to derail.
