HS1 network interface
You may own adjacent land or need to build facilities, transport or infrastructure, or place utility apparatus on or near to the High Speed 1 rail network
If you do, then we need a close working relationship. An integral part of our role is to manage the activities of outside parties who want to carry out works on or near to the railway, or to build bridges under or over land or where that activity impacts in some way on the rail network.
If your building work is NOT alongside HS1 but on another part of our network then please visit our Network Interface page.
The High Speed 1 railway, formerly known as the Channel Tunnel Rail Link (CTRL), is different from the rest of the rail network in that Network Rail (High Speed) operate and maintain it on behalf of HS1. This interface is dealt with by Network Rail (High Speed) Outside Parties team.Network Rail (High Speed 1) Outside Parties Team Charter (90 KB)

All work of this nature, no matter how small, presents a risk to the operational railway or the rail infrastructure and vice-versa. The railway environment is a dangerous one and can impact upon your works. We would be pleased to explain these risks to you.
Within the Outside Parties team, we have engineers committed to managing the impact on High Speed 1 from the works of the developers and providing advice to anyone planning activities near the railway.
