What is ETMS2?

ETMS2 likely refers to the Enhanced Train Management System 2. While specific details may vary depending on the implementation, it is generally understood as an advanced rail transportation management system designed to improve safety, efficiency, and capacity utilization in rail operations. It typically involves the integration of technologies like GPS, communication networks, and on-board computers to provide real-time train tracking, speed control, and automatic braking capabilities, aiming to prevent collisions and optimize train movements. Without further context, pinpointing exact specifications is difficult.
