A Thameslink service calling at the airport was delayed by nearly two hours.
Rail services are expected to be disrupted for the rest of Wednesday due to the fault between London St Pancras and St Albans.
Thameslink issued an alert to passengers which said: “Please do not attempt travel between Bedford and London Bridge until further notice.
“The earlier disruption caused by multiple signal failures has now reoccurred.
“Due to the level of disruption, passengers are advised to delay travelling until later.
“If you do decide to travel, you will need to use alternative means on some or all of your journey, and you will need to allow an additional 60 minutes to travel.”
A depot was also affected, causing delays to trains due to operate early morning services.
Network Rail, which is responsible for signalling, was approached for a comment.
