1 SEPTEMBER 2019 Developing the case for the West London Orbital (WLO) Presentation to the Transport Economists Group 1 Outline of presentation • Background/context • What is the West London Orbital? • Challenges/opportunities along the route • How we have developed the business case Background & Context London is growing • The Mayor’s Transport Strategy sets out a target for 80% of trips to be made by walking, cycling or public transport by 2041, whilst the draft new London Plan identifies a need for 66,000 additional homes per year • To achieve these targets there is a need for an 85% increase in public transport capacity to support a city of over 10.6 million residents by 2041 • Some of this public transport capacity needs to be delivered through major schemes – incremental upgrades to existing services are not sufficient • In addition to funded and committed schemes, a package of major transport interventions is required to support growth in the capital – Currently, these proposals are not fully funded 4 TfL is investigating the feasibility of a number of major schemes 5 6 What is the West London Orbital? The WLO proposal • ~11miles of route with services between Hendon/West Hampstead & Hounslow/Kew Bridge • Service is proposed to open in 2 phases • Phase 1 (4 tph: West Hampstead ->Hounslow) in 2026 • Phase 2 (4 tph: Hendon – Kew Bridge) in 2029 • 15 stations including 4 new stations • Harlesden • Neasden • OOC Victoria Road station • Lionel Road 8 The scheme • Existing infrastructure owned by Network Rail. • West London Boroughs are collectively promoting the scheme • Current services include: • Current freight only line (Dudding hill line) • Busy passenger/ Freight corridor (NLL) • Busy passenger corridor (Hounslow loop) • Scheme is estimated to cost £273m (2017 prices) 10 The WLO scheme is included in the Mayor’s Transport Strategy (MTS) • Initial scheme development work was borough-led • After strong stakeholder support, the MTS was amended to reflect WLO Proposal 88: ‘The Mayor, through TfL, the West London Alliance boroughs and Network Rail, will work towards the delivery of a new London Overground ‘West London Orbital’ line connecting Hounslow with Cricklewood and Hendon via Old Oak, Neasden and Brent Cross’ 11 12 Project Delivery Overview – Indicative timescales Stage 1 - (FY 2018/19) Completed Review and Update existing work, confirm desired outcomes. https://tfl.gov.uk/corporate/publications-and-reports/west-london-orbital Stage 2A and Stage 2B - Stage 2A currently underway (18-24 months) Further Design work (GRIP 2), Business Case development and public consultation Stage 3 - Future Phase (18-24 months) Scheme development to single preferred option (GRIP 3 & 4) and more public consultation Stage 4 - Future Phase (12-18 months) Transport & Works Act Order (or similar) preparation and submission 12 Transport Challenges & opportunities along the route LB Brent, LB Ealing, LB Hammersmith & Fulham, LB Harrow, LB Hillingdon, LB Hounslow and LB Barnet West & north west London is the most significant economic region outside the Central Activities Zone • The region contributing 20% to London’s GDP and having the highest productivity per worker out of any London sub-region. • Its employment clusters are home to agglomerations of major industries, including transport, logistics, pharmaceutical and media. • The region acts as the UK’s global gateway through Heathrow and will become London’s gateway to the north via HS2 at Old Oak Common • The Park Royal/A40/Heathrow corridor has high demand for industrial land use, driven by warehousing and logistics, and airport related activities. • LB Brent and LB Ealing have some of the highest levels of net demand for industrial land in London • These boroughs have a high concentration of Strategic Industrial Locations (SIL) critical for effective functioning to London’s economy as it can accommodate by virtue of their scale, noise, odours, dust, emissions, hours of operation, etc. 14 West and north west London is also a region with significant growth potential • Some of London’s most significant Opportunity Areas (OAs) which would experience transformational change over the next decade are located in the region. • In total, 8 of London’s opportunity areas are located in the region – Total of over 80,000 homes and 100,000 jobs • These characteristics mean the area will play a critical role in delivering new homes and jobs London needs over the next 25years. 15 The opening of the Elizabeth line will bring a step change between west London and the CAZ • The new Elizabeth line will improve radial connectivity between west London and the CAZ & Isle of Dogs • Associated changes to the bus network would provide some improvement in radial connectivity to stations • However, north-south connectivity between town centres in the north of the region e.g. Wembley and Brent Cross; and those south e.g. Hounslow, would not benefit in a significant way. Change in PT journey time at Harlesden (2016 – 2031). Source: WebCAT • Comparing current & forecast journey times with committed improvements show that the north- south corridor sees little improvement at either end. 16 Poor orbital connectivity is a constraint on mode shift in west London 17 These challenges informed our scheme objectives Objective A Enable the delivery of new Objective B homes and jobs in west London Enhance orbital public in line with the principles of Good transport connectivity to and Growth (MTS Policy 21) between major trip attractors (e.g. town centres and Opportunity Areas at Old Oak, Brent Cross and the Great West Corridor) in west Objective C London to support mode shift towards active, efficient and Enhance public transport sustainable modes, and west capacity in west London to London’s continued economic relieve pressure on existing growth corridors and ensure resilience of the public transport network as population grows 18 How we developed the business case Business Case Development • The Strategic Outline Business Case (SOBC) is the first of a 3 stage decision making process (DfT approach) • SOBC developed using the five case model approach – Strategic case: supported by a robust case for change – Economic case: demonstrates value for money – Commercial case: commercially viable – Financial case: affordable – Management case: scheme is manageable • This presentation focuses on the strategic & economic cases 20 A number of work streams informed the development of the business case Strategic modelling What is the overall Technical Development impact of the scheme Capacity Study on the PT network? operations How many homes & assessment jobs can the scheme Are there any technical unlock? show-stoppers at a high level?

Density “WLO dependent” applied assumes a PTAL uplift of 1 resulting in increased density •No change to housing levels for SHLAA Phase 1 & 2 • More flexible approach to planning.
