Heathrow to Paddington trains were disrupted after power fault
Rail passengers have faced disruption due to damage to overhead power cables near one of London's busiest stations.
Trains between Paddington, Heathrow, Oxford and Maidenhead were severely disrupted due to wires collapsing between Paddington and Hayes and Harlington.
Some people got off stranded trains and on to the tracks.
British Transport Police advised people not to leave trapped trains if stranded as train tracks are "very dangerous".
Earlier this month a test train damaged power cables near Paddington forcing services to be cancelled.
Five trains in the section of the collapsed lines were stuck, and some had to be evacuated.
Great Western Railway (GWR) said a limited train service had started to resume to and from London Paddington, however due to train crew and train services being displaced a reduced service will operate.
Heathrow Airport services have resumed after being cancelled for much of Sunday.
Heathrow Express said it sent a rescue service to take passengers on their way to Heathrow Airport back to Paddington where a care team took them on to buses to complete their journey.
Disgruntled passengers took to social media to express concerns over delays and missing flights from Heathrow Airport.
