Major disruption is affecting Heathrow Express and Elizabeth Line trains this morning after a tunnel was closed due to safety reasons.

Network Rail says that there is a water leak in the tunnel and means that only one line is available to be used.

The tunnel is between Hayes and Harlington and Heathrow Terminals 4 / 5.

Elizabeth Line services will be cancelled or revised with no trains running to Heathrow Airport.

Heathrow Express services will be reduced to two trains per hours.

Elizabeth Line passengers can use their ticket on Heathrow Express, Great Western Railway, London Buses and London Underground.
