Introduction 1.1.1 Devon County Council (DCC) commissioned Jacobs to undertake an assessment of the Peninsual Rail Task Force (PRTF) Northern Route scheme. This project seeks to identify the conditions required for a sustainable railway serving the South West peninsula and the likely conclusions of an Economic Case, were a bid for funding to Central Government to be made. 1.2 Background 1.2.1 Following a breach of the railway at Dawlish caused by extreme weather in February 2014, the Government commissioned Network Rail to report on options to maintain a resilient rail service to the South West peninsula in the event of extreme weather events occurring again. The study forms a part of Network Rail’s Long Term Planning Process. 1.2.2 Several options were identified in addition to strengthening the existing route and appraisal work was commissioned by Network Rail to assess the outline business case for each of the seven potential diversionary routes it identified. Economic appraisal of the alternative route options, consistent with Department for Transport (DfT) WebTAG guidance, demonstrated that each option represents poor value for money. 1.2.3 However, the assessments were undertaken under the assumption that the alternative routes would replace the Dawlish line for travel between Exeter and Plymouth and beyond. The appraisal focussed on the costs and benefits of providing an improved service from Exeter to Plymouth and the resilience benefits brought about by reduced disruption. 1.2.4 This report revisits several of the assumptions underlying the assessment of Option 3 (Alternative Route A) - a reinstated railway via Tavistock and
