Main civils construction on Phase 1 (London to Birmingham) of the project began in 2019, and it is currently anticipated that this phase will be fully operational by 2026. Originally intended to link Birmingham and Crewe (Phase 2a) and Crewe to Manchester (Phase 2b) however it was confirmed in 2023 that all of Phase 2 has been cancelled.  The data table contained within the report will only detail the route centre line, however the proposed safeguarding areas (surface and subsurface), depots and station locations will be displayed on the section map. Data source: HS2 Ltd Data update schedule: Quarterly #### HS2 route: nearest overground section Details of the nearest overground section of HS2. Data source: HS2 Ltd Data update schedule: Quarterly ### HS2 safeguarding #### HS2 surface safeguarding An area required for HS2 construction and operation, along one of the proposed routes. It is therefore possible that the property will be demolished for the construction of this route. The Safeguarded Area is generally within 60 metres of the line of the route, though may be more in some areas. Property owners within the Safeguarded Area will be able to ask the Government to buy their property at its unblighted open market value, and will receive additional compensation. However, many compensation schemes are only available to homeowners who purchased their property before the HS2 route was announced. Further information on the compensation schemes and their eligibility rules can be found on the HS2 website. [https://www.gov.uk/government/collections/safeguarding-information-and-maps-for-hs2](https://www.gov.uk/government/collections/safeguarding-information-and-maps-for-hs2) Data source: HS2 Ltd Data update schedule: Quarterly #### HS2 subsurface safeguarding This means that the HS2 route is likely to pass beneath the property in a bored tunnel. This may restrict any subsurface development of the property, and there is the potential for noise and vibration resulting from the construction and operation of HS2. Data source: HS2 Ltd Data update schedule: Quarterly #### HS2 Homeowner Payment Zone This payment scheme is for owner occupiers of rural properties near the HS2 route. However this scheme is only available to those who purchased their property prior to 9th April 2014. Data source: HS2 Ltd Data update schedule: Quarterly #### HS2 Extended Homeowner Protection Zone These are areas that were formerly in a Safeguarding Area, but have since been removed. These properties may still benefit from the Express Purchase Scheme. Data source: HS2 Ltd Data update schedule: Quarterly ### HS2 stations This could be a new station that is being built especially for the new route, or an existing station. While this could be beneficial to the homeowner, regarding future transport links, there may be disruption while the scheme is constructed alongside noise and air pollution for a period of time. Data source: HS2 Ltd Data update schedule: Quarterly ### HS2 depots HS2 maintenance depot meaning trains will be stored, serviced and maintained at this location when they are not in use. Data source: HS2 Ltd Data update schedule: Quarterly ### HS2 noise and visual assessment The visibility assessments are taken from computer-generated models supplied by HS2, and show areas with a theoretical line of visibility to HS2 at different stages of development (construction, initial operation and after 15 years of operation). The model showing visibility after 15 years of operation assumes a growth height of 7.5m of any mitigation vegetation planting. This model is only currently available for Phase 1 and Phase 2a of HS2, and only within 2km of the HS2 line itself. The noise assessments represent sound from HS2 and are generally assessed up to 1km from HS2 in rural areas, and up to 500m in urban areas, though in some cases the assessed area may be greater or smaller than this. This assessment does not take account of any existing background noise from railways, motorways etc. Data source: HS2 Ltd Data update schedule: Quarterly ### Crossrail 1 route The Crossrail railway project links 41 stations over 100 kilometres from Reading and Heathrow in the west, through underground sections in central London, to Shenfield and Abbey Wood in the east. This is now known as the Elizabeth Line. The data table contained within the report will only detail the route centre line, however the new stations and any additional worksites will be displayed on the section map. Data source: Publicly available information sourced by Groundsure Data update schedule: Static ### Crossrail 1 stations This could be a new station that has been built especially for the new route, or an existing station that is being upgraded.  Data source: Publicly available information sourced by Groundsure Data update schedule: Static ### Crossrail 2 route Crossrail 2 is a proposed route connecting Surrey to Hertfordshire through Central London. Further information on the Crossrail 2 project can be found at [http://crossrail2.co.uk](http://crossrail2.co.uk) Please note that the Crossrail 2 project is currently not going ahead and there is no guarantee that the scheme will receive agreement and funding at this time. Data source: Crossrail 2 Data update schedule: Quarterly ### Crossrail 2 stations This could be a new station that is being built especially for the new route, or an existing station. While this could be beneficial to the homeowner, regarding future transport links, there may be disruption while the scheme is constructed alongside noise and air pollution for a period of time. Data source: Publicly available information sourced by Groundsure Data update schedule: Quarterly ### Active railways and tunnels #### Railway tunnels Railway tunnels taken from contemporary Ordnance Survey mapping. This information has been digitised by Groundsure. Data source: Ordnance Survey Data update schedule: Biannually #### Active railways Currently existing railway lines, including standard railways, narrow gauge, funicular, trams and light railways. This information has been derived from Ordnance Survey mapping and OpenStreetMap and digitised by Groundsure. Data source: Ordnance Survey and OpenStreetMap Data update schedule: Annually (Ordnance Survey) and biannually (OpenStreetMap) ### Historical railways and tunnels #### Historical railway infrastructure Railways and tunnels digitised from historical Ordnance Survey mapping at scales of 1:1,250, 1:2,500, 1:10,000 and 1:10,560. This dataset also includes the location of the Royal Mail tunnels beneath London. Data source: Ordnance Survey and Groundsure Data update schedule: Variable #### Abandoned railways Former railway lines, including dismantled lines, abandoned lines, disused lines, historic railways and razed lines. This information has been derived from OpenStreetMap and digitised by Groundsure.
