"Like rail" is a colloquial expression often used in informal conversations to compare or liken a particular situation, behavior, or action to that of a train on a railroad track. It describes the idea of something proceeding or progressing in a steady, predictable, and unwavering manner, similar to how a train moves on its designated path without any deviation.
This term is related to the metaphorical association made between a train and stability, consistency, or predictability. When something is said to be "like rail," it implies that it follows a set course or pattern of behavior without any sudden changes or deviations. It suggests a reliable and steady progression, lacking any form of interruption or distraction.
The use of "like rail" can also connote a lack of flexibility or spontaneity, as trains are confined to a predetermined track and cannot easily change their direction or path. Thus, when something is described as "like rail," it may imply that it is rigid or inflexible, sticking strictly to a set routine or plan without room for adaptation.
Overall, "like rail" is an idiomatic expression employed to compare the smooth and consistent motion of a train on a rail track to various aspects of life or situations that exhibit similar characteristics of stability, predictability, or lack of flexibility.
