Supervised Manoeuvre (SM)

SM.ENT-[30.L2].1This section describes the procedure for the driver to enter SM.

SM.ENT-[30.L2].2The selection of "Supervised Manoeuvre" by the driver shall only be possible if the “safe consist length” information is available on-board.

However, the Supervised Manoeuvre mode does not require that the Train Data set which would fully correspond to the composition of the shunting consist, is captured by the ERTMS on-board equipment. Preconfigured default Train Data shall be used by the on-board with the exception of either:

1. The safe consist length OR,
2. Any value that is obtained by means of a process which involves the driver or by means of a process or an external source with a safety level that could be lower than the one for the safe consist length.

SM.ENT-[30.L2].3If the safe consist length information is available and as long as the safe consist length in front of the engine, taking into account the side of the active cab which defines the front of the engine, is different from zero:

1. The ERTMS on-board equipment shall consider that no valid Train Data is stored on-board
2. The entry, modification and revalidation of Train Data that requires driver validation shall not be possible

SM.ENT-[30.L2].4The 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 entry into SM mode shall be considered by the onboard.

SM.ENT-[30.L2].5The button is enabled only when:

1. The train is at standstill AND,
2. Safe consist length information is available AND,
3. Driver ID is valid AND,
4. Level is 2 AND,
5. No RBC transition order is stored on-board,
6. Only one communication session with a supervising RBC certified with a system version X.Y > 2.2 exists AND,
7. Either:
1. Mode is SB AND the train position is valid and is referred to an LRBG OR,
2. Mode is PT AND valid train data is stored on-board AND the train position is valid and is referred to an LRBG AND no pending emergency stop is stored on-board OR,
3. Mode is FS/AD/LS/OS/SR.

SM.ENT-[30.L2].6After selecting the button, mode transition will be only performed after receiving an authorisation from the trackside.

The Main window is presented to the driver with all buttons disabled and the Hour Glass symbol (ST05) is displayed until the SM mode is authorised or rejected by trackside.

ST05: Hour glass

SM.ENT-[30.L2].7When the message “Supervised Manoeuvre Authorisation” is received from the RBC, the DMI shall display the default window with the SM mode symbol (MO24). The planning, speed and braking information is updated and the SM01 or SM02 symbol indicating the authorised direction may change ; the driver shall adapt the direction controller accordingly.

SM01 and SM02: SM authorised direction indicator (forward and backward)

SM.RUN-[30.L2].2If a Trip condition is received from trackside while running in Supervised Manoeuvre mode, a transition to Trip mode is performed (see section TR - Trip / Post Trip (TR)). After a transition to Post Trip mode, the driver is presented with the possibility to resume a Supervised Manoeuvre with the button .

SM.RUN-[30.L2].3If the safe consist length information is acquired from an external source and it becomes unavailable, the DMI shall display “Safe consist length no longer available” and, if the train is not at standstill, it shall command the service brake. The location based information stored on-board shall be shortened to the current position either immediately or, if the train was not at standstill, only when it has reached standstill.

SM.RUN-[30.L2].4At standstill, the ERTMS on-board equipment shall give the possibility to the driver to request a new Supervised Manoeuvre authorisation (e.g. in case of zig-zag movements when the end of a Movement Authority is reached) by selecting the button.

SM.RUN-[30.L2].5The 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 continue in SM mode shall be considered by the onboard.

SM.RUN-[30.L2].6After selecting the button, the on-board awaits a new authorisation from the trackside.

The Main window is presented to the driver with all buttons disabled and the Hour Glass symbol (ST05) is displayed until the SM request is authorised or rejected by trackside.

SM.RUN-[30.L2].7When the message “Supervised Manoeuvre Authorisation” is received from the RBC, the DMI shall display the default window. The planning, speed and braking information is updated and the SM01 or SM02 symbol indicating the authorised direction may change ; the driver shall adapt the direction controller accordingly.

SM.RUN-[30.L2].8If the text message “SM refused” or “SM request failed” is displayed, the driver shall inform the signaller about the situation. The driver and signaller shall apply non-harmonised rules.

SM.EXT-[30.L2].1When all Supervised Manoeuvre movements to be performed in SM mode are finished, the driver shall exit Supervised Manoeuvre mode manually.

SM.EXT-[30.L2].2The 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 exit SM mode shall be considered by the onboard.

SM.EXT-[30.L2].3The button is only enabled when:

1. The Mode is SM, AND
2. The train is at standstill.

When the driver selects Exit SM, the transition to SB is triggered (see section SB - Stand By (SB)) and the communication session with the RBC is terminated.

SM.EXT-[30.L2].4Additionally to the transition mentioned previously (i.e. SM ( SB, when the driver selects ), the following mode transitions can be triggered from SM mode:

1. NP mode. Transition triggered when the ETCS on-board is powered off as indicated in section Power off the ETCS on-board (PWR).
2. SH mode. Transition initiated manually by the Driver, see section SH.MAN Manual entry into SH (MAN).
3. SB mode. Transition triggered when the driver has not selected Maintain Shunting and the desk is closed as indicated in section OFF.CLS Close the desk (CLS).
4. NL mode. Transition manually initiated by the Driver (see section NL - Non-Leading (NL)).
5. TR mode. Automatic transition triggered when a trip condition is received from the trackside, see section TR - Trip / Post Trip (TR)).
6. SF mode. Automatic transition triggered in case of a fault, see section SF - System Failure (SF).
7. IS mode. Transition triggered when the driver isolates the ETCS on-board equipment, see sectionIS.ENT Entering Isolation mode (ENT).
8. SN mode. Transition usually initiated by an order from the Trackside, see section SN - National System (SN) . This transition also includes a transition to level NTC either initiated manually by the Driver, see section LTR.TRS.DRV Level transition initiated by driver (DRV) or ordered by the Trackside, see section LTR.TRS Level transitions (TRS).
