In the context of railway operations and timetables, the letter "A" commonly signifies "Automatic interlocking." This refers to a signaling and control system that automatically manages the routing of trains through junctions and crossings without requiring manual intervention from a dispatcher. Automatic interlocking is designed to enhance safety and efficiency by preventing conflicting train movements and enabling smoother traffic flow through busy sections of the rail network.

The other options do not accurately capture the specific meaning associated with "A" in timetables. "Authorized crossover," for example, would refer to a specific designated point where trains are allowed to switch tracks, but it does not relate to a standard abbreviation used in timetables. Similarly, "Association of railways" and "Acknowledged stop" do not represent established terminology in the context of timetables, making "Automatic interlocking" the most fitting and relevant interpretation of the letter "A."
