# Staff responsible (SR)

SR-[L12.N].1In Staff Responsible (SR) mode, the driver is allowed to move the train under their own responsibility in an ERTMS/ETCS equipped area.

The driver shall be authorised by the signaller to start a movement in SR mode by means of an operational instruction, except in the case of starting a movement in ERTMS/ETCS level 1 or 2 with trackside signals.

In SR mode the driver moves the train under his own responsibility. However, the ETCS on-board equipment supervises the train movements against a ceiling speed and a given distance determined by a National Value that can be modified as indicated in section SR.LIM Modify the SR speed and distance limits (LIM).

The ETCS on-board equipment also supervises train movements against running in the direction opposite to the train orientation.

SR-[L1.N].1To restart trains that have not been tripped after an emergency situation, in level 1 with trackside signals, the driver shall run on sight up to the next trackside signal by considering the instructions and / or restriction issued by the signaller, if any.

- If the train is not located at an ETCS stop marker the authorisation is valid from the current location of the train to the next ETCS stop marker.
- If the train is located at an ETCS stop marker this authorisation is valid from this ETCS stop marker to the next one, the driver is authorised to pass the EOA. The driver shall:
  1. Receive European Instruction 7 from the signaller,
  2. Check the applicable speed limit,
  3. Use the override function if requested, and wait for the symbol (MO03) indicated below, see section OVR.USE Use override function (USE).

     MO03: Override EOA is active

  4. Start the train,
  5. Not exceed the override EOA speed while the Override EOA is active symbol (MO03) is displayed.
- If allowed by non-harmonised rules, the driver can be authorised by the signaller to pass several consecutive ETCS stop markers with only one written order.
- If the signaller can establish that the track is free, then the signaller can exempt the driver from running on sight in SR mode according to non-harmonised rules.

## SR.LIMModify the SR speed and distance limits (LIM)

SR.LIM-[L12].1The driver can modify the value of the SR mode speed limit and of the given distance when the train is at standstill and in SR mode.

When modifying the SR mode speed limit or the given distance, the driver is responsible for entering reasonable values.

If a train movement is detected while the driver is entering the SR speed/distance limits, the brake command is triggered.

The speed limit given by the driver prevail over the National/default value.

SR.LIM-[L12].2If the driver activates the Override procedure while already in SR, the supervised distance, as determined by the distance in a National Value or entered by the driver, is reset.

SR.LIM-[L1.T].1To modify the SR speed and distance limits, the driver shall press the button on the Default window of the DMI as indicated in Figure SR.LIM-[L1.T].F1.

## SR.RUNRunning in SR (RUN)

SR.RUN-[L12.N].1When the Staff Responsible symbol (MO09) is displayed, the driver shall:

1. Run on sight, unless an operational instruction exempts him from running on sight in SR,
2. Not exceed the applicable speed limit determined by a National Value or set by the driver,
3. In ETCS level 1 and 2 without trackside signals, stop at the next ETCS stop marker, inform the signaller about the situation and follow any instructions given.

MO09: Staff Responsible

SR.RUN-[L12].1The driver must check if the track is free, if points are correctly positioned, and must respect the existing line-side information (signals, speed boards etc.).

SR.RUN.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.

SR.RUN-[L2].1If receiving a track ahead free request from the RBC, the driver is requested to enter the track ahead free information (see section OTH.TAF Track Ahead Free (TAF)).

SR.RUN-[L1.T].1The permitted speed, target distance and target speed are not shown by default on the DMI. The driver can toggle on and off the display of these parameters by touching the area indicated in Figure SR.RUN-[L1.T].F1.
