A rail is a long, narrow strip of steel that forms part of the track system on which trains travel. Rails are laid down in parallel lines and are fixed to the ground with ties or sleepers, creating a stable and smooth surface for train wheels.

Rails are essential components of railroads and are typically made from strong, durable steel to withstand the heavy loads and constant wear from train traffic.

A rail is a fascinating bird that inhabits marshes and wetlands around the world. With their unique body structure, they are well-adapted to live in these environments. Rails are characterized by their long, slender bodies, short wings, and strong legs, which allow them to navigate through dense vegetation and wade in shallow waters. They have a secretive nature, often hiding among the reeds and grasses, making them challenging to spot. Rails are skilled swimmers and agile runners, able to move quickly and gracefully across various terrains. Their diet consists of small invertebrates, seeds, and plant matter, which they forage for while probing the muddy ground or picking food from vegetation. Known for their distinctive calls, rails communicate with a variety of vocalizations, from sharp squawks to melodic trills. These remarkable birds play an important role in the wetland ecosystems they call home, contributing to the overall biodiversity and functioning of these habitats.
