E6 ENGINEERING WORKS ALL LINES Stratford and North Greenwich Following several instances - between Stratford and North Greenwich - where Protection Masters have been found to be on the track prior to the passage of the last timetabled train, all PMs must note the following: The Signal Operator at Neasden Service Control Centre can be contacted on Auto 40879 to determine that the last "timetabled" train has passed through the area. RESTRICTIVE ENGINEERING WORKS The Site Person in Charge responsible for work published for Asbestos Exclusion Zones, Keep Clear Areas, Wheels Free or Areas where no other work that affects the integrity of the signalling can take place must ensure that the TAC incident desk receives confirmation, between 21:30 and 23:00, that the published work will be taking place on the shift concerned. If no confirmation is received by 23:00 TAC may disregard the restriction and other staff may be permitted to work within the affected area. Contacting the signaller when passage of last train not witnessed When contacting the signaller, because it has not been possible to witness the passage of the last train, protection staff must state the line, station, platform number and if known, the number of the last train. Do NOT contact the signaller until after the published time for traction current to be switched off. BAKERLOO LINE Marylebone and Paddington, both APD signals maintenance Lambeth North and Waterloo south end tailwall, both APD signal & points maintenance CENTRAL LINE White City platform 3, middle road Protection staff should be aware, that although White City middle road platform 3 is fed from the Park Royal to Wood Lane westbound traction current feed, the last train into the middle road platform approaches in an eastbound direction.

CIRCLE & HAMMERSMITH AND METROPOLITAN LINES King's Cross (Disused station) Following the discovery of discarded syringes in the area of Kings Cross disused station, staff are to be extra vigilant whilst passing through or undertaking works in that area. If any such items are identified please ensure these are reported through the EIRF system and immediately advise your manager. Page 8 of 11

Liverpool Street - Monitoring equipment At Liverpool Street station, on the Circle & Hammersmith and Metropolitan lines and 200m into tunnels towards Aldgate, automated survey monitoring equipment is installed, fixed to the tunnel and track to monitor movement during construction works above. Please avoid touching this equipment, or obstructing in any way the barrel shaped prisms mounted low down on track and trackside - particularly their line of sight to the instruments hanging from the tunnel crowns. If you think you may have inadvertently touched or damaged this equipment, please contact Jocelyn Donovan at Jocelyn.donovan@ipcmonitoring.com. REVISED TRACK ACCESS ARRANGEMENTS ALDGATE TO MOORGATE AND TOWER HILL TO WHITECHAPEL ALL As a result of a formal incident investigation into a number of recent protection irregularities, it was identified that the following enhancement to track access arrangements will be trialled on these traction current sections: Aldgate to Moorgate Inner Rail Moorgate to Aldgate Outer Rail Tower Hill to Whitechapel Eastbound Whitechapel to Tower Hill Westbound. Staff requiring access to any of these traction current sections in this complex area, must NOT contact the track access control until after the published switching off time for traction current. The track access controller will book you on once they have confirmation that the last train has cleared the area and traction current has been switched off. There is no need to contact the signaller if you do not witness the passage of the last train or trains over these four traction current sections. You must however, continue to test for traction current on all traction current sections that you will be accessing. Aldgate and Liverpool Street, all APD signals maintenance DISTRICT LINE EMERGENCY CONTACT BETWEEN NOTTING HILL GATE AND BOUVERIE PLACE Protection Masters working on the Traction Current Sections "Notting Hill Gate to Bouverie Place, both" should note the tunnel telephone lines (for emergency discharge of traction current) are controlled by the Metropolitan Service Controller at Baker Street. Staff working in this location should telephone 910 in the event of an emergency; this information should be entered in their log books.

REVISED TRACK ACCESS ARRANGEMENTS ALDGATE TO MOORGATE AND TOWER HILL TO WHITECHAPEL ALL As a result of a formal incident investigation into a number of recent protection irregularities, it was identified that the following enhancement to track access arrangements will be trialled on these traction current sections: Aldgate to Moorgate Inner Rail Moorgate to Aldgate Outer Rail Tower Hill to Whitechapel Eastbound Whitechapel to Tower Hill Westbound. Staff requiring access to any of these traction current sections in this complex area, must NOT contact the track access control until after the published switching off time for traction current. The track access controller will book you on once they have confirmation that the last train has cleared the area and traction current has been switched off. There is no need to contact the signaller if you do not witness the passage of the last train or trains over these four traction current sections. You must however, continue to test for traction current on all traction current sections that you will be accessing.
