Heathrow Express services between the airport and London’s Paddington station were suspended for 30 minutes this morning after a fire.
A blaze at West Ealing station stopped the service for around half-an-hour, as thousands of passengers arrived at the airport ahead of the Olympic opening ceremony.
Around 125,000 people are expected to arrive in London today for the start of the Games.
Heathrow Express and Heathrow Connect services are now back up and running.
