Balise for Automatic Train
Protection (ATP) and Operation (ATO)

Intertech Rail also manufactures equipment for ATP (Automatic Train Protection) and ATO (Automatic Train Operation).


ATP is a type of rail protection system that continuously checks the speed of the train and checks if it is compatible with the speed allowed in that segment, and if it is allowed by that type of signaling on the railway section.


If the train is not following that maximum speed it may include a speed decrease or even an automatic train stop. It prevents that for any situation if the train passes a red light it suffers a penalty and the train stops automatically regardless of the driver's actions.


ATO (Automatic Train Operation)


It works similarly to ATP, but is used as a traffic guide or rapid transit system whose main objective is the safety of people.


This system is used to mitigate risks in railway operation and automate the operation of trains and the degree of automation is indicated by the degree of control of the train and the railway, where GA4 is when the train is controlled automatically without operators on board.

Frequently Asked Questions

  • What is ATC (Automatic Train Control)?

    Automatic Train Control (ATC): ATC is a system that monitors and controls the movement of trains, ensuring they operate safely and efficiently. ATC includes various subsystems, such as train detection, speed control, and trackside signals. ATC is designed to help prevent accidents by automatically enforcing speed limits and stopping the train if necessary.

  • What is ATO (Automatic Train Operation)?

    Automatic Train Operation (ATO): ATO is a system that automates the driving of trains. ATO is responsible for starting, accelerating, and stopping the train, as well as maintaining the speed and position of the train on the track. ATO can be used to reduce the workload of train drivers, increase efficiency, and reduce the risk of human error.

  • What is ATP (Automatic Train Protection)?

    Automatic Train Protection (ATP): ATP is a safety system that ensures trains do not exceed speed limits or run past signals. ATP continuously monitors the train's speed and position, and automatically applies the brakes if necessary. ATP can help prevent train accidents caused by human error, such as speeding or running a red light.
