Tunnels and Underground Incidents

The aims of the group are to:

• support the development of the NFCC’s Annual Plan;

• deliver agreed priorities and projects within the agreed project

plan;

• support the development of professional expertise and

guidance;

• provide advice and speak on behalf of the fire sector in the

specialist areas within the remit of tunnels and underground

incidents;

• share good practice, evaluation and learning between fire and

rescue services and appropriate partners to encourage the take

up of new and innovative schemes that deliver positive

outcomes for communities;

• engage and influence key stakeholders; and

• collaborate to deliver beneficial outcomes where appropriate.

HS2 Overview

345 miles of High Speed track

£55.7Bn budget

48 high speed trains an hour

Around half the population able to access the High Speed Network


Key Railway Characteristics• Trains will travel up to 360 km/h – dependent on route alignment and infrastructure

• Powered by OLE – 25Kv

• HS2 will be an all ticketed service and passenger numbers will be limited to 550 persons for a 200m

train and 1100 for a 400m train.

• 18 trains/hour in each direction.

• 8 planned new stations

• Tunnels – Bored or cut and cover

– 9 tunnels on Phase 1

– 7 tunnels on Phase 2

• Numerous viaducts – 0.5 - 4+km

• The trains will be managed by a Network Integrated Control Centre located at Washwood Heath,

Birmingham

• Only electric rolling stock will be used for revenue operations.

• There will be no hazardous freight on HS2.

• Maintenance trains may be diesel or electric - fire suppression fitted if diesel.


Key Elements• Tunnels

– Cut and cover or bored

– Intervention/ventilation shafts

– Tunnel portals

• Stations

– Phase 1 – Euston, Old Oak Common (Acton), Birmingham Interchange (NEC) and Birmingham Curzon Street

– Phase 2 – Manchester Airport, Manchester Piccadilly, East Midlands Hum (Toton, Nottinghamshire) and Leeds

• Depots

• Phase 1 – Calvert (Bucks), Washwood Heath

• Phase 2 – Crew, Staveley (Derbyshire), Leeds

• Network Integrated Control Centre – NICC – Washwood Heath

• Open Route

– Bridges and viaducts

– Rail system compounds

– Cuttings/Embankments


HS2

General Fire Objectives


General Fire Objectives• The overarching fire objectives are the protection of;– The infrastructure occupants – passengers, operational staff, railway

workers, maintenance staff, visitors, members of the fire and rescue service (FRS) and other emergency staff.

– Infrastructure and associated assets – property protection

– Business of providing high-speed rail services – business continuity

– The environment.

• As Statutory Undertaker HS2 are not required to pass through the normal Building Control process, therefore a Qualitative Design Review (QDR) process for consultation and assurance for building design, construction and trial/operation will be utilised to seek a position of no objection/agreement with the FRS.


HS2

Key Engagement Principles


Key Engagement Principles• HS2 has provided a single and central coordinating function for

engagement with the FRS and to act as single point of contact between Contractors and FRSs - HS2 FRS Liaison Manager

• The FRS will provide a central group - HS2 Fire Service Liaison Group to aid coordination.

• Route wide design features (tunnels, shafts, portal buildings, open route, construction etc) will be principally agreed by the HS2 Fire Service Liaison Group.

• Location specific features will be agreed by FRS Local Group(s) but engagement managed via the HS2 central function.

• Process for resolving route wide and local issues established – HS2 FRS Resolution Group.

• Liaison and Local Groups will reach a position of agreement/no objection on design, construction and testing/operational stages of the project.

FRS Strategic / Tactical Considerations?


FRS Operational Considerations• Access – cuttings, embankments, tunnels and open route.

• Potential delayed response and intervention

• Effective communication – FRS, NICC and emergency services.

• Minor/major Incident?

• Resource requirements – Local, 13 & 16, Regional and National

(NR).

• LRF – Multi agency response plan?

• JESIP

• Exercising for specific infrastructure.

• Training, operational competence and preparedness.

• 7.2.d) and enforcement inspections.
