  • Structure
  • Current position
  • access provision - actual and an ideal
  • cost drivers
  • Work in progress
  • national system level
  • route and area specific
  • key lessons
  • Opportunities
  • Implications for planning and delivery
  • Conclusions

3
  • Current position - access provision
  • Network has finite capacity, yet over time
    increasing demands have been placed upon it
  • A small number of critical junctions routes
    need more access
  • in Kent gt70 of delay minutes attributed to key
    junctions - only 3 of access available at those
    sites
  • But globally, current engineering access not
    fully utilised

4
  • Current position - compared to an ideal
  • General Characterisation of Existing ROTR Work
    Pattern 
  • Characterisation of Ideal ROTR Work Pattern

5
  • Current position - cost drivers
  • Short possession access not effective or
    efficient
  • Long possessions give most efficient use of
    engineering resources - optimum length driven by
    engineering activity
  • Performance regime incentivises under-planning
  • Clear need for industry business case
    optimisation
  • value of running incremental trains vs.
    incremental cost of engineering work in shorter
    access windows
  • Unconstrained Projects - major impact on
    maintenance and renewal plans
  • Renewals - item / scope change - and then
    programme slip

6
  • Work in progress - national system level
  • Network Access Unit (Leeds) established to
    co-ordinate delivery of engineering access
  • Integrated Planning Units (IPUs) taking overall
    view of possessions use within Network Rail
    Regions
  • Area planning Teams - local ownership from T-46
  • Collection of industry KPIs on possession
    performance
  • Maximise use of individual possessions
  • Optimum value tools - e.g. POET (possession
    optimisation efficiency tool)

7
  • Work in progress - route specific
  • Targeting best industry outcomes for a particular
    route
  • London-Norwich
  • London-Brighton
  • Bristol-Birmingham
  • Southampton West Midlands Action Team
  • Scotland RSSB
  • 2004/05 timetable wins in 2003/04 where
    possible
  • cross industry teams developed plans
  • NR, IMCs, TOCs, FOCs and RSSB

8
  • Work in progress - key lessons 1
  • Tri-partite meetings between IMC/NR/TOC are
    essential to achieve best results for possession
    requirements
  • Annual workload should be assessed to identify
    cyclical maintenance for key junctions and plan
    engineering access accordingly
  • Renewals plan should be fixed when cyclical
    maintenance is planned - at the latest
  • Resource utilisation should be considered over
    wide geographical scope main trunk routes at
    weekends, suburban commuter routes in midweek
    nights

9
  • Work in progress - key lessons 2
  • Treat cyclical possessions and work within them
    as a project
  • plan, monitor and control work accordingly
  • Main routes with 3 tracks - access for
    patrolling inspection is problematic
  • must work with TOCs to achieve optimum value
    solution
  • Look at safety and efficiency of site access
  • provide additional and improved access points
    where these would give significant extra site
    working time

10
  • Opportunities
  • SWAT has identified real efficiency savings for
    2003/04
  • 58 increase in track mile hours, 32 fewer
    possessions
  • weekend blocks are c100 more productive c20
    of work currently done at the weekend
  • Scotlands plan for maintenance from 2005
  • reduces total engineering access hours
  • increases work hours whilst keeping paid hours
    constant
  • weekend work moves to 11 hour shifts, weeknight
    access to 7 hours shifts
  • unlocks increases in output efficiency, volume
    and quality
  • facilitates reductions in delays and TSRs

11
  • Implications for planning and delivery
  • Need clear view on projects and renewals
    workbanks
  • and plans that are stable within industry
    planning horizons
  • Need to consider broad patterns of access
    relevant to different types of route
  • site optimisation model gives best possession
    times for mtce renewal work - but needs better
    train value info
  • but also optimise overall demand for resource
  • Blockades often necessary and most efficient
    solution
  • pre-determined formula giving visibility on cost
    of blockades would remove significant levels of
    risk

12
  • Conclusions
  • Finite capacity - used for train paths or
    engineering - two issues cannot be separated
  • Utilisation strategies must balance effectiveness
    and efficiency of engineering access against the
    value of the transport opportunities foregone
  • Access optimisation needs clear view of costs and
    values of passenger traffic, freight traffic and
    engineering work
  • Maintenance, renewal and project work is
    fundamentally linked - planning across all 3 must
    be integrated
  • Optimal practical solutions come from tri-partite
    dialogue between engineers, network controllers,
    and TOC/FOCs
