Line where ERTMS is over posed to the national signalling system

The train in front to the signal is an ERTMS train and there’s an available MA for that train

(from its current position to the first ETCS Stop Marker). Driver is asked to follow DMI info.

1) The train in front to the signal is not an ERTMS train and there isn’t any available MA for that train

Driver is asked to look outside and follow indication provided by signals.

2) The train in front to the signal is an ERTMS train and there isn’t any available MA after the signal

Virtual track section 1 not yet cleared or an SCMT train is still occupying section x.

Pre conditions for the High Density Function: • ERTMS L2 Baseline 3

• The train running first (train 1) connected with RBC and with train integrity function active on-board

• Position report (after a Virtual Track Circuit) valid including the confirmation of the Train Integrity checked on-board

• The train 2, following the train 1, connected with RBC

• The signal c) with the symbol X active

HD ERTMS System Requirement for Train and for EVC ERTMS/ETCS

HD ERTMS have to guarantee the high density headway only for chain of trains with this

minimum characteristics (Gamma Trains) :

• Max lenght a 200 m;

• time delay for breaking system application< 4,5 s .;

• 140 % Weith Breaking;

• 1,0 m/s2 average deceleration for EB in the speed range 0-100 km/h

The Train using the HD ERTMS functionalities must be use ETCS EVC BL3 R2 with:

• the “ETCS smart sleeping” functionality (without the breaking of the train in case

of losing connection with tail EVC)

• Position Report (Q_lenght parameter ) to RBC to check the safe tail of the train.

• Cab Radio for GPRS and MT with professional Filter agains interferences

• 0,9 the parametre of “rolling stock correction factors”
