Positive Train Control

Federally mandated integrated safety system preventing train collisions, overspeeding, and switch violations.

Driving Difficulty Level 4 / 5

Advanced

Based on vigilance required, reaction window, and braking penalty severity.

menu_book System Overview

Positive Train Control (PTC) is the modern North American digital train control framework. Integrating GPS location, digital track databases, wayside interface units, and wireless radios, it continuously governs train movements.

settings How It Operates

check_circle Monitors train location with centimeter accuracy using GPS and wheel tachometers.
check_circle Continuously calculates dynamic braking curves for the entire train mass based on track gradient, signal aspects, and speed limits.
check_circle Pre-warns the engineer visually and audibly if an overspeed condition or stop signal approaches.
check_circle Intervenes with penalty braking to bring the train to a complete stop if human action is inadequate.
