HS2 has begun tunnelling towards central London as the first tunnel boring machine started work on the 4.5-mile Euston Tunnel from Old Oak Common. The tunnel is the final deep-bore section on the high-speed route between London and Birmingham.
The facility, with an 18-month construction period, will service the new high-capacity Stadler trains entering operation from 2026 on the busy Móstoles–Humanes corridor.
