Study Notes
Track Movement Authority (TMA) Procedures
- Purpose of TMA: A verbally dictated movement authority used when ERTMS (European Rail Traffic Management System) equipment fails or is unreliable, during extensive line side signal equipment failures, or when a train needs to relocate during a Start of Mission.
- Situations Requiring TMA: Used for trains with ERTMS failures, extensive signaling issues, those unable to set up in ERTMS, those needing to move due to brake demands from ERTMS loss, or for trains without ERTMS equipment.
- Limited Scope: A TMA is granted for a single movement in one direction; if a return movement is needed, a new TMA is required.
- Communication Before TMA: Train Controller confirms with the driver about the Level Crossing List, Weekly Operating Notices, and relevant E Notices. Missing information necessitates details of speed restrictions.
- Communication Failure: If communication lapses during TMA grant, the TMA is considered ungranted until restored.
- Clear Understanding Required: Before granting a TMA, a clear understanding between the Train Controller and Driver is necessary about start and end marker boards, authorized distance, routes at stations, and exit marker board locations.
TMA Grant Confirmation
- Confirmation Process: A TMA is only granted once the Train Controller provides a unique authority number.
- Documentation: Completed TMA forms must be kept for audits.
TMA Speed Limits
- Speed Guidelines: Maximum permitted speeds in a TMA are not targets; drivers must adjust based on various restrictions. These include permanent restrictions (like turnouts or platforms), temporary/emergency restrictions (noted on the TMA), and level-crossing conditions.
- Freight Train Speed: The maximum permitted speed of a freight train or locomotive within a TMA is 60 km/h.
Pre-Movement Actions
- ETCS/ERTMS Isolation: Onboard ETCS/ERTMS equipment must be isolated before starting the movement.
- Adherence to Authority: Do not exceed the maximum speed authorized by the Train Controller.
During Movement
- Speed Restrictions: Drivers must adhere to all permanent, temporary, and emergency speed restrictions.
- Level Crossings: Be prepared to stop at level crossings unless confirmed as clear and safe.
- Weekly Operating Notices: The Train Controller will inform drivers about temporary/emergency speed restrictions if necessary.
Driver Change
- Driver Change Notification: A new driver must inform the Train Controller of the change, both for recording and documentation.
TMA Extension
- Extension Procedures: If a TMA needs extending, the train must be brought to a stand for confirmation, and the extended TMA limits re-evaluated with the Train Controller. The extension must be documented on the TMA form.
- Movement Safety: If unsure, a train must stop to speak with the Train Controller rather than potentially moving into dangerous situations (like approaching platforms or TMA limits).
Reaching the Exit Marker Board
- Transition to Level 2: Train Controller and driver determine if the train can transition to Level 2 Full Supervision or if the TMA needs extending. All necessary actions are to be finalized.
Train/Locomotive Transition Requirements
- ETCS/ERTMS Restoration: Onboard ETCS/ERTMS has to be restored to allow transitioning to Level 2 Full Supervision
- Start of Mission: The start of mission sequence (if needed) is concluded
- Appropriate Operating Mode: The appropriate operating mode is selected.
- Authorization: Passing the marker board is only permitted when authorized by the Train Controller.
Non-Transition Considerations
- Failing ETCS Equipment: If ERTCS equipment doesn't function or a movement authority can't be granted, a TMA extension or a new TMA must be established.
- Completion Confirmation: After passing the limits of the first TMA the driver needs to inform the Train Controller before cancellation.
Additional Considerations
- EOA/Signal Passing: Override needed when allowed to pass EOA or a color light signal without a MA.
- Turnouts: Turnouts must be correctly positioned, with a maximum speed limit of 25 km/h.
- Train Speed: Speed depends on permanent/emergency restrictions, level crossings, and maintainable stopping distances.
