SH.PS.1The button is a delay-type button, meaning that the driver must keep pressing during 2 seconds to be considered by the DMI. If the button is pressed by the driver for less than the 2 seconds, no valid request to maintain Shunting mode shall be considered by the onboard.

SH.PS.2The button is enabled only when:

1. The Mode is SH AND,
2. The Passive shunting permitted input signal is received from the train interface.

The passive shunting input signal can have the following values:

1. Passive shunting permitted
2. Passive shunting not permitted.

The passive shunting input shall have the value “Passive shunting permitted” if the train is immobilized by means of a braking system that can be released from another cab after its activation. Otherwise, the value is set to “Passive shunting not permitted”.

SH.PS.3After selecting the Maintain Shunting button, when the driver closes the desk (see section OFF.CLS Close the desk (CLS)), the ETCS on-board enters PS mode. The notion of responsibility of the driver is not relevant for the PS mode.

The ETCS on-board enters Passive Shunting mode when:

1. “Passive Shunting permitted” input signal is received.
2. Desks are closed
3. “Continue Shunting on desk closure” function is active, which is generated after the Maintain Shunting button is selected.

SH.PS.4Passive shunting may be rendered unavailable (e.g. on decision of the Railway Undertaking) by permanently setting the input signal to “Passive shunting not permitted”.

## SH.RUNRunning in SH (RUN)

SH.RUN-[L12.N].1When Shunting mode is active, the Shunting symbol (MO01) is displayed:

MO01: Shunting

The Shunting mode speed limit determined by a National Value shall not be exceeded.

The driver is responsible for:

1. Remaining inside the Shunting area.
2. Train movements and Shunting operations.

SH.RUN-[L12.N].2While the Shunting symbol (MO01) is displayed, the driver shall apply the non-harmonised rules.

SH.RUN-[N].1When a driver has to run on sight, the driver shall proceed with caution, controlling the speed having regard to the visibility of the line ahead, so that it is possible within the free visible part to stop short of any vehicle, stop aspect or obstacle on the infrastructure. This does not apply to unexpected obstacle entering the track zone within the stopping distance.

SH.RUN-[L0N.N].1Network specific clauses to indicate how operate in SH mode in level 0 and NTC.

SH.RUN-[L0N1.T].1The Shunting mode speed limit is not shown by default on the DMI. However, the driver can toggle on and off the Shunting mode speed limit display by touching the area indicated in Figure SH.RUN-[L0N1.T].F1.

SH.RUN-[L12.N].3To protect and restart Shunting movements in case of emergency situations, the driver shall apply non-harmonised rules.

SH.RUN-[L12.N].4When a Shunting movement needs to pass a defined border of a Shunting area, the driver shall apply the non-harmonised rules.

SH.RUN-[L12.N].5When a Shunting movement is tripped by passing a defined border of a Shunting area, the driver shall apply the non-harmonised rules.

SH.RUN.1If a Trip condition is received from trackside while running in Shunting mode, a transition to Trip mode is performed (see section TR - Trip / Post Trip (TR)).

After a trip has occurred, the driver shall continue running in the same direction only if the driver has received permission by by means of a European Instruction 2 from the signaller.

SH.RUN.2The remote shunting information is defined as a two state output with the following values:

1. ERTMS/ETCS on-board is in a mode permitting remote shunting
2. ERTMS/ETCS on-board is not in a mode permitting remote shunting.

The remote shunting output value “ERTMS/ETCS on-board is in a mode permitting remote shunting” shall be used by the train to allow a radio remote control unit to control the train.

The remote shunting output value “ERTMS/ETCS on-board is not in a mode permitting remote shunting” shall be used by the train to inhibit any radio remote control.

## SH.EXTExit form SH (EXT)

SH.EXT-[L12].1When all Shunting movements to be performed in SH mode are finished the driver shall:

1. Exit Shunting mode manually.
2. Ensure that no traction unit remains in the Maintain Shunting status.
