How the European Rail Traffic Management System ERTMS works in terms of controlling the speed of the train?

ERTMS has two main components, which include GSM-R, a radio system for enabling communication between the driver and the traffic management centre, and ETCS, an automatic control system that helps to control speed limits of a train by communicating with the driver.

What is ERTMS Signalling?

The European Rail Traffic Management System (ERTMS) is a single European signalling and speed control system that ensures interoperability of the national railway systems, reducing the purchasing and maintenance costs of the signalling systems as well as increasing the speed of trains, the capacity of infrastructure …

What is railway interoperability?

Interoperability supports safe and technical compatibility of trains and infrastructure and enables the railway to compete more effectively with other forms of transport. It establishes common standards and assessment processes for new, upgraded or renewed rail vehicles, infrastructure and components.

How does the European train Control system work?

ETCS is the core signalling and train control component of ERTMS, the European Rail Traffic Management System. ETCS continuously calculates a safe maximum speed for each train, with cab signalling for the driver and on-board systems that take control if the permissible speed is exceeded.

How does Etcs work?

Technology. ETCS is the core signalling and train control component of ERTMS, the European Rail Traffic Management System. ETCS continuously calculates a safe maximum speed for each train, with cab signalling for the driver and on-board systems that take control if the permissible speed is exceeded.

What is Cbtc signalling?

Communications-based train control (CBTC) is a railway signaling system that makes use of telecommunications between the train and track equipment for traffic management and infrastructure control.

What is common safety method?

The Common Safety Methods (CSMs) describe how the safety levels, the achievement of safety targets and compliance with other safety requirements should be fulfilled. The CSMs are directly applicable and enforceable in the Member States.

What is CBTC technology?

Communication-based train control (CBTC) is a signalling system that uses communication between onboard and trackside equipment for train operation and control. CBTC has been widely adopted in recent years on monorails, commuter trains, metros, and other urban railway services.

What makes up the European rail traffic management system ( ERTMS )?

ERTMS comprises of the European Train Control System (ETCS), i.e. a cab-signalling system that incorporates automatic train protection, the Global System for Mobile communications for Railways (GSM-R) and operating rules.

What are the components of the ERTMS system?

The ERTMS System is based on two main system’s components: ETCS (European Train Control System) and GSM-R (Global System for Mobile Communications – Railway).  ETCS is an Automatic Train Control system (ATC) developed by UNISIG in cooperation with the European Union, Railway stakeholders and the GSM-R industry.

Which is the system design authority for ERTMS?

ERA plays the role of system design authority for ERTMS. In that respect, it must establish a transparent process to manage, with the contribution of the sector’s representatives, any system changes .

How are ERTMS related to the relationship between train and track?

The application levels of ERTMS are a way to express the possible relationships between track and train. These relationships are related to the trackside equipment used, to the way trackside information reaches the on-board units and to which functions are processed trackside and on-board.
