The German signalling system for HS lines LZB (LinienZugBeeinflussung)
• Each centre permanently connected to all interlockings andtrains of its area as well as to adjacent centers for in andout relationships;
• The trackside vital computer sends cyclically, to every onboard computer, data concerning the length of theavailable braking distance and the localization of brakinginitiation in respect of the braking train capacity.

The Italian signalling system for HS lines
• Speed up to 156.0 mph
BACC (Blocco Automatico a Correnti Codificate) national light signalsblock system based on continuous transmission from coded trackcircuits and on board repetition of trackside light signals, and SCMT(Sistema Controllo Marcia Treno), which is an overlie discontinuoussystem for speed control. These HS lines are also used byconventional trains (to be soon upgraded to ERTMS);
• Speed up to 187.5 mph
ERTMS (European Rail Traffic Management System) level 2. In theItalian application ERTMS operates without overlapping on othersystems and without trackside signals.Only ERTMS equipped trains can run on such HS lines. The lack of aback-up system (ERTMS level 1 or similar) is balanced by a very highlevel of redundancy of subsystems involved. 9

Why ERTMS?1. Interoperability: European Commission supports the
development of operational and technical interoperabilitywith unified signalling equipment in order to open railwaymarkets to all train operators;
2. Safety: ERTMS equipments are designed and produced incompliance with CENELEC standards;
3. Performance: high speed can be reached using the lowestamount of time distance between the trains (in Italy only2’30’’ between two trains running at 187.5 mph);
4. Availability/Reliability: due to the particular ERTMSarchitecture, there are less equipments along the lines,reducing fault probability and improving system reliability.

ERTMS levels
• ERTMS Level 1:
Overlay using Eurobalises and track side signals;
• ERTMS Level 2:
Fixed Block Authority is communicated directly from theRadio Block Center (RBC) to the train using GSM-R.Wayside track signals are optionally required;
• ERTMS Level 3:Introduction of “moving block”. Wayside track signals arenot required.

Which ERTMS? ERTMS level 1
• Discontinuous system working on an underlying and already existingsignalling system; provides a continuous speed supervision;
• Movement authorities and track description data are generated byelectronic Lineside Equipment Unit (LEU), located by side of thetracks, on the basis of information received from external signallingsystems and track circuits;

• Movement authorities are transmitted to the train via waysideequipments called balises;
• The on-board sub-system calculates a dynamic speed profile takinginto account the train braking characteristics and commands the brakeapplication if necessary;
• Lineside signals are required. Loop (cable or radio) could be used inorder to immediately refresh information related to the clear signalaspect (infill function).

Features of ERTMS Level 1
Semicontinous system working on an underlying and already existing signalling systemProvides a continuous speed supervision system, which also protects against overrun of the authorityMovement authorities and track description data are generated by electronic Lineside Equipment Unit located by side of the tracks on basis of information received from external signalling systems and track circuits.
Then Movement Authorities are transmitted to the train via devices called balises (located all along the tracks) that can send telegrams to the on-board subsystem.
The on-board sub-system (ETCS) calculates a dynamic speed profile taking into account the train running/braking characteristics and commands the brake application if necessary.
Lineside signals are required.
