On 23 February 2017, Royal Assent was granted for phase one of HS2, which comprises a new high speed railway between London and the West Midlands with stations at London Euston, Old Oak Common, Birmingham Interchange, and Birmingham Curzon Street.
HS2 in Hillingdon
The railway will run in a tunnel from Old Oak Common into Hillingdon under South Ruislip and Ruislip Gardens before emerging at Ickenham High Road. It will then travel overground before ramping up onto a viaduct over the Colne Valley and then descend to ground level before going into a tunnel under the M25 and further west.
