8.180 This section covers Network Rail‟s plans for renewals in CP5. Its proposed volumes of asset renewal during the period are set out in Tables 8.11 to 8.13. These tables set out some of the key volumes planned by Network Rail; they do not capture all volumes proposed. We have worked with Network Rail to develop appropriate
renewal volume indicators for CP5 and these will be included in its delivery plan. The company‟s planned renewals expenditure and efficiencies are set out in Tables 8.14 to 8.16.
Volumes
8.181 Network Rail has forecast track renewals volumes for CP5 based on the new ways of working defined by its track policy. This has made comparison of volumes to CP4 difficult. Conversion of the volumes to kilometres of rail, sleeper and ballast renewal, and number of S&C units show that the company plans to deliver fewer kilometres of
rail and sleepers, more kilometres of ballast and significantly more S&C units. These changes are mainly driven by the new policy, but also include accelerated renewals. 8.182 Signalling volumes, as measured in Signalling Equivalent Units (SEUs), are forecast
to be much higher in CP5 than in CP4. Total SEU renewals almost double, from approximately 5,800 in CP4 to approximately 11,000 in CP5. The increase is largely driven by renewals associated with delivery of NOS. The SEU volume for CP5 shows a marked increase in ETCS delivered units, in line with the national strategy. The number of level crossings renewals to be delivered also increases from 123 in CP4 to 499 in CP5, again largely driven by NOS and requirements for obstacle detection. 8.183 Network Rail forecasts that its new civils asset policy requires a step-change in civil
asset renewals volumes, with increases relative to CP4 in almost all work types. Volumes of underbridge works are forecast to increase by 101%, volumes of
overbridge works by 7%, volumes of tunnels works by 58% and volumes of coastal and estuarial defence works by 141%.
8.184 Volumes of renewals relating to buildings assets have not been captured during CP4 but have been forecast for CP5 for franchised and managed station assets.
8.185 Plans for electrification and fixed plant show increased volumes of conductor rail and low voltage DC (LVDC) distribution cables compared to CP4. AC distribution volumes are significantly lower than in CP4 as are all DC distribution volumes with the
exception of LVDC distribution cables. A high volume of signalling power cable renewals is planned to address a recently identified backlog of work. The plans include new volume measures for CP5, including volumes of overhead line mid-life refurbishments and of signalling power cable renewals.

Efficiency
8.186 Network Rail has proposed CP5 exit renewals efficiencies of 15.8% for the network, 15.5% for Scotland and 15.9% for England & Wales170.
8.187 The company has set out plans for its renewals efficiencies in a series of business cases. Key areas for delivering efficiencies are:
(a) development of policies which Network Rail considers to be better optimised for minimum whole life cost;
(b) asset information efficiencies to be delivered by ORBIS; (c) better scheduling of work;
170 In Network Rail‟s SBP it presented renewals efficiency for „core‟ asset renewals only, which it
defined as track, signalling, civils, buildings, telecoms, and electrification and plant. It presented figures excluding the efficiencies which are built into its CP5 asset policies. Figures presented here are for all renewals expenditure and include the efficiencies which are built into its CP5 policies.
(d) more effective contractual relationships; (e) standardisation of processes; and (f) multi-skilling of staff.
8.188 Efficiencies are discussed by main asset category later in the chapter.
Expenditure
8.189 Network Rail forecasts renewals expenditure of £13.6bn across the network, £1.48bn in Scotland and £12.1bn in England & Wales. This level of expenditure is considerably higher than in CP4 despite efficiencies achieved in CP4 and forecast to the end of CP5, and despite an accounting change moving costs from renewals to maintenance. Network Rail‟s key proposals which drive this increase in expenditure are:
(a) the rationalisation and centralisation of signalling control through implementation of NOS;
(b) a large increase in proposed expenditure on civil structures and earthworks renewals resulting from the application of the updated policy and a better
understanding of asset condition, degradation and risk, the net effect of which is forecast to deliver a step-change improvement in the level of civil assets risk on the network;
(c) renewals brought forward from future control periods to deliver work more
effectively, for example as the result of enhancement schemes, or to make use of access before it is limited by traffic growth;
(d) proposed expenditure on improving asset information systems and management, ORBIS; and
(e) a proposal for additional investment schemes where Network Rail believes there is a business case. For example it has proposed additional investment in
improved information technology, Research & Development (R&D), safer and faster isolations and a new system to provide alerts to track workers.

Outputs
8.190 Network Rail has forecast the asset condition and performance metrics which its policies will deliver as described in chapter 3. For both condition and performance its approach is, in the main, to keep asset specific metrics constant at the level forecast for the end of CP4. However, for civil structures, earthworks and off-track it is planning an improvement in overall condition. For track, number of failures per year causing delays of greater than 10 minutes is forecast to increase marginally. For electrification and plant the same metric is forecast to increase by approximately 10%. For
structures, the number of open risk items with a risk score of greater than 20 is expected to reduce significantly by the end of CP5.
