Trains between Luton and London are still suspended as the evening rush hour begins.
First Capital Connect is advising passengeres not to travel due to severe disruption on the network.
Significant overhead line damage at Hendon and flooding at Balcombe mean trains on the Thameslink route are disrupted.
Network Rail is not expected to repair the damage today.
First Capital Connect said on its website: “We advise you not to travel unless your journey is essential and if you have to travel to do so outside the evening peak if at all possible. We expect to be unable to operate any trains until at least 06.00 on Saturday. We will provide any update to this here as soon as we can.”
Customers travelling between Central London and Luton (for trains to/from stations Bedford) should use Great Northern services between London King’s Cross and Hitchin for replacement buses between Hitchin and Luton (these buses will not run after approx. 22.00) or Greenline bus services between London Victoria Buckingham Palace Road and Luton (your tickets will be accepted).
Customers travelling to/from Luton Airport should use bus route A to/from Luton.
After 22.00, replacement buses will operate directly between London St Pancras International and St Albans for onward trains to/from Luton.
