South Western Railway has apologised after Isle of Wight commuters were among those left stranded on a powerless train for more than two hours near Battersea, London.
The service left Southampton Central station at 7.30am this morning (Tuesday) but lost power as it reached Battersea.
Yards from the platform, passengers were left trapped in an airless train.
In a statement, South Western Railway said:
“We’re sorry to passengers who have had their journeys delayed today owing to an electrical failure near Clapham Junction. This was caused by a piece of damaged equipment from a train which came into contact with the conductor rail, causing the electricity supply to fail.
“The issue has now been resolved and we are working with Network Rail to recover normal service as soon as possible.
“We ask that customers check before they travel.”
