Network RUS: Electrification ‘Refresh’
- 30 year perspective as part of Long Term Planning Process 'to
give funders’ choices for investment in CP6 and beyond'
- 3 key objectives:
–Identify the extent of lines to be electrified –Consider the case for conversion of third rail DC network to AC –Include a consideration of lines to be electrified to maximise the ability of freight operators to use electric locomotives
3
Work programme to date
- 2013 - Working Groups 1, 2 and 3. Freight Electrification and DC
– AC workshops
- A number of bilateral meetings held with interested stakeholders
- Business cases being produced for priority options
- Costs being produced in parallel
4
The starting point
- Baseline electrified network with all known committed schemes
completed
- Most likely view of services using the network at that time

The initial sift
- Key measure of likely business case is traffic converted to length of
route electrified (the ‘conversion ratio’)
- For each remaining diesel service group calculate the length of
electrification required for it to convert to electric
- Look at where service groups overlap and combine options where the
conversion ratio can be improved (with a limit on option size)
- Consider requirements for diversionary routes, and add these to the
most appropriate options
- Order the options by their conversion ratio, and consider how the case
for each would be affected by the earlier higher-priority schemes
- Group options into tiers, where 1 = highest conversion ratio and 6 =
lowest

Wider factors
- Capture other key issues :
1.Efficient use of infrastructure – reduction in diesel vehicle kilometres on ‘existing’ electrified network per STK electrified 2.Efficient use of rolling stock – ‘island fleet’ measure at TOC level 3.Value of released infrastructure – number of high speed / high frequency long distance conditional output aspirations which could be delivered by electric traction 4.Diesel rolling stock released – number of released vehicles adjusted for age 5.Passenger diversionary route capability – average annual diverted traffic on key flows able to convert 6.Freight – overlap with freight option 7.Strategic fit with other schemes, wider considerations
- Results for factors 1-5 are grouped into six categories and allocated star ratings
- 5 stars indicates a result in the top 1/6 for that measure
11
Choosing options for appraisal
- Likely to be a case for undertaking full business case appraisal for:
– Options with passenger conversion ratio of either tier 1 or tier 2 – Options in tiers 3 or 4 which perform well against the wider criteria
- Where the ratio analysis doesn’t suggest that there is a better case for
combining options, but that there is nevertheless a relationship between them we have grouped into packages
- Examples of the types of relationship are:
– The case for a given option relies on an earlier phase having been completed – The options may be served by the same TOC, rolling stock or depot
- Subsequent slides show LNW options being appraised

Approach to business case appraisal
- Business cases being produced for shortlisted options using the economic appraisal
framework defined by funders (e.g. WebTAG by DfT)
- Key measure of Value for Money is the Benefit Cost Ratio (BCR), which reflects…
- Benefits = Net sum of (dis)benefits to users & non-users, and indirect taxation
impacts – Improved journey times & journey opportunities – Increased capacity – The environment
- Cost = Net cost to the transport budget (Δ Capex + Δ Opex + Δ Revenue):
– Initial infrastructure cost – Changes in operating costs – Changes in revenue arising from time savings and/or new service patterns
20
Journey times & journey opportunities
- Potential timetable impacts considered include:
– Journey time improvements resulting from superior acceleration/deceleration characteristics of electric trains – Opportunities to improve connectivity through the introduction of new service patterns – ‘End of wires’ issue; toolkit of ‘solutions’ ranging from interchange & shuttle service, bi-mode trains, loco-hauled services, diesel under the wires, backfilling by extension of other services
- Often the ‘best’ solution differs according to whether one takes a
‘financial’ or ‘socio-economic’ perspective
- Drives revenue, user benefits, non-user benefits, and indirect taxation
impacts
21
Capacity
- On train capacity
– Direct (e.g. replacement of diesel loco-hauled stock with multiple units) & indirect (e.g. release of cascadable diesel units to meet growth elsewhere on the network) – Replacement of ‘short’ DMUs - is there a VfM case for the additional capacity? What is the envelope in which electrification becomes a VfM enabler of additional capacity? – PDFH provides the tool for valuing the demand response and user benefits
- Network capacity – infrastructure costs avoided in the context of
accommodating additional train services where the network is (or will be) at capacity – scheme specific benefit
22
The environment
- Reducing the environmental impact of rail services
– Greenhouse gases
- Estimating emissions (tCO2e) – rail energy consumption rates & DECC marginal
emission factors
- Valuation – DECC values reflecting national targets and abatement costs1
- Body of evidence growing on embedded carbon1
– Other environmental benefits (e.g. noise, other particulate matter) typically not quantified for economic appraisal purposes, but benefits noted in AST
- Reducing the environmental impact of transport through encouraging mode-shift to rail
– Highway impacts including air pollution, noise & greenhouse gases reflected in the ‘Marginal External Cost’ of car use values; quantum of benefit linked to rail demand generation
1 Note the cost of carbon is ‘internalised’ in the price of electricity if using DECC’s energy price forecasts. Also, the majority embedded emissionsrelating to materials are likely to be covered by the EU ETS and will therefore also be “internalised”
23
Operational costs
- Rolling stock; lease, fuel consumption, maintenance &
availability, VTAC (as a proxy for track wear & tear) –Anticipated cost of new build fleets; sensitivity testing & scenarios important
- Maintenance of new electrification assets; average rates or the
electrification asset usage charge
- Number of diagrams, incl. potential for journey time savings to
reduce resource requirements
- Replacement of ‘short’ (2-car) DMUs
24
Capital costs
- Whilst awaiting cost estimates appraisals produced on basis of
‘placeholder cost’ based on indicative cost per STK – the ‘Atkins range’ referenced in the 2009 RUS
- These costs are being reviewed to ensure consistency of unit
rate assumptions and with conclusions emerging from ECAM process
25
Planned next steps
- Reporting to Northern Task Force of emerging BCRs for
northern options September 11th
- Ongoing review of costs
- Completion of appraisals during October, to be followed by
Working Group
- Strategy development October onwards
- Draft for consultation to be published alongside report of
Northern Task Force in February 2015
