Is the Channel Tunnel Part of High Speed 1?

No. The **Channel Tunnel (Chunnel)** and **High Speed 1 (HS1)** are **distinct but connected infrastructure assets**:

Channel Tunnel

• What: **50.5 km (31.4 mi) rail tunnel** under the English Channel.
• Operator: **Getlink (Eurotunnel)** — concession until 2086.
• Services:
  • **Eurostar** (high-speed passenger: London–Paris/Brussels/Amsterdam).
  • **LeShuttle (Eurotunnel)** — **vehicle-carrying trains** (cars, trucks, coaches) — **Folkestone ↔ Calais**.
  • **Freight trains** (DB Cargo, Europorte, etc.).
• Ownership: **Getlink SE** (publicly traded).

High Speed 1 (HS1)

• What: **109.9 km (68.3 mi) high-speed railway** from **London St Pancras International → Channel Tunnel portal (Folkestone)**.
• Opened: **Section 1 (2003), Section 2 (2007)** — **full line 2007**.
• Speed: **300 km/h (186 mph)** — **UK's only true high-speed line**.
• Operator: **HS1 Ltd** (consortium: Borealis, Ontario Teachers', etc.) — **30-year concession**.
• Services: **Eurostar** (international), **Southeastern Highspeed** (domestic: Kent → London in ~30 min).

Relationship

**HS1 ends at the Channel Tunnel portal.** **Eurostar trains run on HS1 → enter Channel Tunnel → continue on French LGV Nord / Belgian HSL 1 / Dutch HSL-Zuid.** The **tunnel is the cross-Channel link**; **HS1 is the UK high-speed approach**. **LeShuttle (car train) uses classic lines (South Eastern Main Line) to reach the tunnel—NOT HS1.**

Analogy: **HS1 = driveway; Channel Tunnel = bridge; LGV Nord = highway.** Separate owners, operators, regulations, but **seamless for Eurostar passengers**.
