What is the purpose of yard limits?

Yard limits serve a specific purpose in railroad operations, primarily focused on allowing increased flexibility in train movements within designated areas. When yard limits are established, they permit extra trains to occupy the main track without requiring formal train orders. This is effective for facilitating operations within a yard or other defined area, as it frees up the need for additional communication or authorization that typically accompanies train movements outside of these limits.

Establishing yard limits helps streamline logistics, especially in busy areas where multiple trains may need to operate in close proximity. It creates an environment where trains can maneuver more freely and efficiently, which can be crucial during peak operational times.

While yard limits do involve considerations related to safety, compliance, and overall train management, the primary focus is on the operational flexibility they provide for trains in that specific zone, directly aligning with the intent of allowing extra trains to utilize the main track without additional orders.
