PTC Server

- Displays Authorities and Speed Restrictions- Enforces Authorities and Restrictions- Warns Crew when Approaching Limits- Warns of Roadway Workers performing

Authorized Work on Track- Reports Location to Server

- Tracks Trains closely- Monitors Field Conditions

• Track Circuits• Switches• Defects Detectors

- Computes Authority Limits

- Transmits Movement Authorities & Speed Restrictions to Trains
