Western Rail Access to Heathrow (WRAtH) has been delayed by up to two years after the business case and private funding sources rolled back due to the impact of Covid-19 on air travel. The brand new railway line, which would have linked Heathrow to Reading via a short spur off the GWML at Langley required a Development Consent Order to progress.

The Development Consent Order is expected to be submitted late next year.
