What is indicated by the term YL in railroad language?

The term YL stands for "Yard Limits," which is a specified area or zone on a railroad where certain operational rules apply. Within yard limits, train movements are typically governed by specific signaling and speed restrictions, which are important for safely managing the movement of trains, cars, and other railroad equipment in the vicinity of a yard.

Yard Limits are crucial for ensuring safe operations because they define where trains may operate at higher speeds compared to the surrounding areas, which often have different rules. When a train is within yard limits, it is important for crew members to be aware of potential movements of switching locomotives and other trains that may be entering or leaving the yard. The application of yard limit rules helps prevent accidents and ensures that all personnel involved in train operations understand the required protocols.

Other options, while relevant in different contexts, do not accurately represent the term YL as it pertains specifically to railroad operations. Therefore, Yard Limits is the correct interpretation of YL within the scope of railway terminology.
