Thee Evolution of Train Control: Merging Signaling andAutomation

Modern rail transportation depends on they chewless integration of signaling systems andd Automatic Train Control (ATC) for safe, high-capatious operations. This integration forms the cre of contemprary railway management, moving beyond simple signal indicatations to a networked, intelligent system that continuously monitors and controlls train movements.
