Trip / Post Trip (TR)

TR-[112021].1The Trip (TR) mode is activated when an event (dangerous situation) causes a train to trip. The transition to Trip mode can be performed from FS, LS, OS, SR, SB, SH, SN or UN modes, when one of the Trip conditions is fulfilled.

The driver is informed about the reason for the train trip.

The driver has no responsibility for the train movement in Trip mode.

TR-[22].1The Trip (TR) mode is activated when an event (dangerous situation) causes a train to trip. The transition to Trip mode can be performed from FS, AD,LS, OS, SR, SB, SH, SN or UN modes, when one of the Trip conditions is fulfilled.

The driver is informed about the reason for the train trip.

The driver has no responsibility for the train movement in Trip mode.

TR-[30].1The Trip (TR) mode is activated when an event (dangerous situation) causes a train to trip. The transition to Trip mode can be performed from FS, AD, SM, LS, OS, SR, SB, SH, SN or UN modes, when one of the Trip conditions is fulfilled.

The driver is informed about the reason for the train trip.

The driver has no responsibility for the train movement in Trip mode.

TR.MSRImmediate measures (MSR)

TR.MSR.1The Trip mode is indicated to the driver with the Trip symbol (MO04).

MO04: Trip

When the Trip symbol (MO04) is displayed, the driver shall assume that there is a dangerous situation and therefore, the driver shall perform all actions necessary to avoid or reduce the effect of this situation.

Once the train is at standstill and the Acknowledgement for Trip symbol (MO05) is displayed with a flashing frame, the driver shall acknowledge the symbol.

MO05: Acknowledgement for Trip

TR.MSR-[B3M1]Once the TR mode is acknowledged, the text message associated to the TR reason is no longer displayed.

TR.MSR-[L0N1.T].1To acknowledge the trip mode, the driver shall press the button with a flashing frame, as indicated in Figure TR.MSR-[L0N1.T].F1.

Figure TR.MSR-[L0N1.T].F1: Acknowledgement for trip button (touch screen technology)

TR.MSR-[L2.T].1To acknowledge the trip mode, the driver shall press the button with a flashing frame, as indicated in Figure TR.MSR-[L2.T].F1.

Figure TR.MSR-[L2.T].F1: Acknowledgement for trip button (touch screen technology)

TR.MSR-[L0N1.S].1To acknowledge the trip mode, the driver shall press the button associated to the symbol of Acknowledgement for trip as indicated in Figure TR.MSR-[L0N1.S].F1. Both the Acknowledgement for Trip symbol (MO05) and the Ack button displayed with a flashing frame.

Figure TR.MSR-[L0N1.S].F1: Acknowledgement for trip button (soft key technology)

TR.MSR-[L2.S].1To acknowledge the trip mode, the driver shall press the button associated to the symbol of Acknowledgement for trip as indicated in Figure TR.MSR-[L2.S].F1. Both the Acknowledgement for Trip symbol (MO05) and the Ack button displayed with a flashing frame.

Figure TR.MSR-[L2.S].F1: Acknowledgement for trip button (soft key technology)

TR.MSR-[L12].1If the ETCS level is 1 or 2 , the mode immediately changes to Post Trip once the driver acknowledges the Trip mode and so, the Trip symbol (MO04) is replaced by the Post Trip symbol (MO06, located in area B7).

MO06: Post Trip

In PT mode, the command of the emergency brake is released. The driver is responsible if preforming a reverse movement.

In PT mode, the driver is informed about the reason of the brake application.

TR.MSR-[L12.N].1When the Post Trip symbol (MO06) is displayed, in case an immediate reverse movement is necessary due to an emergency, the driver decides or is instructed by the signaller to perform a reverse movement to minimise the effect of the train trip because it is necessary, the driver shall do so following any instructions given by the signaller.

When the Post Trip symbol (MO06) is displayed, in case an immediate reverse movement is necessary due to an emergency, the driver decides or is instructed by the signaller to perform a reverse movement to minimise the effect of the train trip because it is necessary, the driver shall do so following any instructions given by the signaller.

After performing a reverse movement, as soon as the train/Shunting movement is at a standstill, the driver shall inform the signaller about the situation and follow any instructions given.

TR.MSR-[L12.N].2The authorised distance to perform a reverse movement is given for a national value. If during the reverse movement, this national distance is over-passed, the brakes are applied.

The “PT distance exceeded” text message is displayed when the brake command is triggered due to the detection of a train movement exceeding the distance allowed for reverse movement in Post Trip mode. In this case, the brake command shall be released at standstill.

TR.MSR-[L12].2When the Post Trip symbol (MO06) is displayed, in case a reverse movement is not necessary, the driver shall inform the signaller about the situation and follow any instruction given.

TR.CONContinue a mission after a Train Trip (CON)

TR.CON.1After a trip has occurred, the driver shall continue running in the same direction only if the driver has received authorisation by means of a European Instruction 2 from the signaller.

TR.CON-[N].1In the case of a train/Shunting movement not required to be moved after a trip, the signaller shall order the driver to remain at standstill and to perform End of Mission by means of European Instruction 3.

TR.CON-[L0N].1Once the driver acknowledges the Trip mode, if the ETCS level is 0 or NTC and the train data stored is no valid, the mode shall directly change to Shunting mode, see section SH.RUN Running in SH (RUN).

Consequently, the Trip mode symbol (MO04) is replaced by the Shunting symbol (MO01, located in area B7).

MO01: Shunting

TR.CON-[L0].1Once the driver acknowledges the Trip mode, if the ETCS level is 0 and there is valid train data stored, the mode directly changes to the Unfitted mode, see section UN - Unfitted (UN).

As a result, the Trip mode symbol (MO04) is replaced by the Unfitted mode symbol (MO16, located in area B7).

MO16: Unfitted

TR.CON-[LN.V].1After the acknowledgement of the trip mode, if the level is NTC and there is valid train data stored, the mode directly changes to the National system mode, see SN - National System (SN) section.

Consequently, the Trip mode symbol (MO04) is replaced by the National system symbol (MO19, in level NTC, the location of the symbol is not specified).

MO19: National system

TR.CON-[L12].1To continue running in ETCS levels 1 or 2, the driver shall receive the European Instruction 2 with all additional instructions given by the signaller. According to the task to be performed, the driver shall select Start or Shunting and follow the instructions given in the European Instruction 2.

TR.CON-[B41.L12].1After the acknowledgement of the trip mode and the train is in Post Trip mode, if the ERTMS/ETCS level switches to 0 or NTC and no valid train data is stored on board, the mode shall change to Shunting mode, see section SH - Shunting Mode (SH).

TR.CON-[B41.L12].2After the acknowledgement of the trip mode and the train is in Post Trip mode, if the ERTMS/ETCS level switches to 0 and valid train data is stored on board, the mode shall change to Unfitted, see section UN - Unfitted (UN).

If in Post Trip mode, if the ERTMS/ETCS level switches to NTC and valid train data is stored on board, the mode shall change to SN, see SN - National System (SN) section.

TR.CON-[L1].1If the driver selects Start in level 1, a proposal of change to Staff Responsible mode is presented to the driver.

The driver shall follow the steps indicated in section SR.ACK Acknowledge of SR (ACK).

TR.CON-[L2].1If the driver selects Start in level is 2 the following options can be proposed by the RBC:

  1. SR mode: if a proposal to change to Staff Responsible mode is presented to the driver, the driver shall follow the steps indicated in section SR.ACK Acknowledge of SR (ACK).
