What is the function of an Intermediate Boundary Fence?

The function of an Intermediate Boundary Fence is primarily to separate roadway from non-roadway territory. This fencing is crucial for ensuring the safety of roadway workers by clearly defining areas designated for their operations, thereby reducing the risk of accidental entry onto tracks where trains may operate. By establishing a distinct boundary, the fence helps to manage the movement of personnel and vehicles, maintaining safety protocols required in active rail environments.

Options relating to securing train stations, preventing access to mainline tracks, and indicating speed limits for trains do not accurately reflect the primary role of an Intermediate Boundary Fence. While preventing access to mainline tracks may seem similar, it does not encompass the broader purpose of distinguishing between different operational zones within the rail environment.
