ATC (Automatic Train Control)
Automatic train control system. It's the technological and functional evolution of the Automatic Train Protection (ATP).
AV/AC (High Velocity-High Capacity)
System of specialised lines and vehicles for High Velocity and consequent High Capacity.
Doubling
Transformation of a single-track line into a double track.
ERA (European Railway Agency)
The European Union's (EU) agency that establishes the mandatory requirements for European railways and builders in the form of technical specifications for interoperability, which apply to the trans-European rail system. The ERA sets common safety objectives, methods, and indicators and follows Directive 2004/49 / EC as amended.
ERTMS (European Rail Traffic Management System)
System of functional and operational integration of the various railway networks defined within the European Union and which, at the operational control level, provides for the ETCS system.
ETCS (European Train Control System)
System that includes various national ATC (Automatic Train Control) operating systems. The ATC systems are made up of traditional and innovative signalling systems and can be realized through RSC (Continuous Signal Repetition) and RSDC (Continuous Digital Signal Repeater).
Guideline
Set of railway lines with characteristics of importance for the volume of traffic and the transport relations carried out on it; it joins together centres or main nodes on the network.
Node
Conventional location that defines a railway area usually coinciding with important metropolitan areas, characterized by a high density and relative complexity of medium-large stations and other railway installations interconnected by various lines that represent the continuation of the main itineraries that enter the same node as well as other lines. It is designed to facilitate the circulation management of different traffic flows and alternative routes, i.e. belts and service braces.
SCC/CTC (Command Control System/CTC Large network)
It's a system for regulating circulation and nodes with performance characteristics superior to traditional systems for centralized traffic control.
System
Production unit of a local railway company with an identifiable jurisdictional area on the railway network. They can belong to both the Infrastructure Manager and the transport companies.
Terminal
Infrastructure suitable for intermodal transport, mostly suitable for the exchange between carriers of large load units, with or without small area warehouses.
