Thameslink and Great Northern passengers between Hitchin and Peterborough faced severe travel disruption due to wire damage.
The cancellations began at around 1.10pm yesterday (Tuesday, August 16), and have been caused by faulty overhead wires.
Thameslink, Great Northern and LNER services were disrupted through Huntingdon and St Neots.
Disruption continued throughout the evening, but lines reopened later the same night.
A spokesperson for Great Northern said at the time: "Damage to the overhead wires between Peterborough and Hitchin means all lines are blocked.
"Trains running between these stations may be delayed by up to 60 minutes or cancelled.
"Trains are unable to run between Hitchin and Peterborough.
"This will impact direct services between Horsham and Peterborough.
"If you're making a journey between Peterborough and Hitchin, you should consider travelling another way, or much later on once the service starts back up again."
The disruption also affected passengers on other long-distance routes between London King's Cross, Stevenage and Peterborough.
