Introduction 1.1 Background and Project Overview The re-modelling of the Kings Cross (KX) Area will include the implementation of European Train Control System (ETCS) Level 2 on the East Coast Mainline (Engineers Line Reference (ELR): ECM1) between Kings Cross 0MP and Yaxley 73MP (south of Peterborough) and will include the Moorgate line (ELR: MEB1), Hertford Loop (ELR: HDB) and the Cambridge Line towards Royston (ELR: SBR). Generally, high Level activities will include: 1. Kings Cross (KX) Permanent Way (P-Way) Layout remodelling; 2. Overhead Line Equipment (OLE) system design and construction associated with the KX remodelling; 3. Electrification and Plant (E&P) systems design and construction – KX remodelling and Phase 1, including KX station systems; 4. Civil Engineering design and construction associated with KX remodelling and Phase 1 requirement’s; 5. Telecommunications and Global System for Mobile Communications Railway (GSM- R) design and construction associated with KX remodelling and Phase 1 requirement’s.1 The full extent of the project is shown in Appendix A. 1.2 Proposed Works This report, however, will focus of the works on the remodelling of the immediate vicinity of Kings Cross Railway Station. This will include, alteration of track layout on the approach to KX Station and design and construction of new and renewal of existing OLE equipment, as well as associated E&P, civil engineering and telecommunications works, required to accommodate the aforementioned. By undertaking the above works in the KX area, it will enable the reopening of the east bore of Gasworks Tunnel, easing congestion both in and out of KX Railway Station. A plan of the proposed remodelled area, overlaid atop the existing track layout, is provided in Appendix B. To enable the above works, a site compound will be established on recently disused site on York Way, just south of Gasworks Tunnel at grid reference TQ 303 835. A temporary access will then be constructed from the compound, which sits above the railway, to track level. 1 Network Rail. 2016. Pre-construction Information: Kings Cross Remodelling ECML/ETCS Phase 1. 2 2. Methodology 2.1 Desk study The Multi-Agency Geographic Information for the Countryside (MAGIC) and Network Rails’ GI Portal and GeoRINM were used to identify the following; Statutory designated sites, such as Special Protected Areas (SPA), Special Areas of Conservation (SAC), Sites of Special Scientific Interest (SSSI), National Nature Reserves (NNR) and Local Nature Reserves (LNR), within 1 km of the project boundaries; Ancient woodland within 100m of the project; Tree Preservation Orders (TPOs) within 100m of the project; Watercourses which flow beneath (culverted) or adjacent to the railway within the project extent; Ponds within 250m of the project (Great crested newts can travel up to 500m from the breeding ponds. Research by English Nature (now Natural England) (2004) suggests that if the habitat within 250m of their breeding ponds is suitable then newts will be unlikely to travel further than this2). 2.2 Field survey A Preliminary Ecological Appraisal (PEA) of the project area was carried out on the 7th and 8th July 2016. Weather conditions were warm, clear and dry with temperatures of approximately twenty degrees Celsius. The survey included an assessment of lineside and adjacent habitats and their potential to support protected species in line with the Chartered Institute of Ecology and Environmental Management (CIEEM) guidance3. Invasive species, listed on Schedule 9 of the Wildlife and Countryside Act, 1981 (as amended) were also recorded. Where waterbodies were visible from the railway an assessment was made on their habitat suitability for great crested newts4. 2.3 Limitations Only the east bore of Gasworks Tunnel could be accessed during this survey. Safe access could not be sought into any of the other bores of this tunnel due to the movement of trains. Other bores of the tunnel, which are to be subject to intrusive works, will be subject to survey at a later date, when conditions permit safe access. Only the east bore of Copenhagen Tunnel could be accessed during this survey. No intrusive works will be undertaken within this bore of the tunnel. The other bores of Copenhagen Tunnel, where works will be undertaken, will be subject to survey at a later date, when conditions permit safe access. With regards to invasive plant species listed on Schedule 9 of the Wildlife and Countryside Act 1981 (as amended), this PEA focusses primarily on the identification of Japanese knotweed, Himalayan balsam, giant hogweed, cotoneaster species and rhododendron. 2 Cresswell & Whitworth, 2004.
