Passengers travelling between St Albans City and London St Pancras will need to use replacement buses, as no trains will be running.
Thameslink will have no services between Bedford and Mill Hill Broadway, while East Midlands Railway will have rail replacement buses operating between Bedford and Hitchin.
Replacement bus services will run between:
- Bedford and Hitchin
- Luton Airport Parkway and Hitchin (via Luton)
- Harpenden and Potters Bar (via St Albans City)
- Mill Hill Broadway and Luton
- Bedford and Luton
If you are heading from London, the closure means trains to St Albans City will terminate short at West Hampstead Thameslink or Kentish Town, while trains to Bedford will terminate at West Hampstead Thameslink or Mill Hill Broadway.
Jenny Saunders, customer service director for Thameslink, said: “I’m sorry our Thameslink passengers north of Mill Hill Broadway on the Bedford route will have to take a rail replacement bus this weekend because of this essential engineering work.
“This will take longer than the normal train ride, so please go online to check your journey before you set out and allow any extra time.”
300 metres of new track is being laid in St Albans train station and drainage systems upgraded in Radlett as part of a series of improvement works.
Further engineering work is scheduled with additional closures planned for June 20-21 and June 27-28.
Dan Matthews, operations director for Network Rail, said: “We appreciate everyone’s understanding while these important improvements take place, and we’re sorry to anyone whose journey will be affected.
“This weekend we’re carrying out further improvement work to make the railway more reliable and resilient for passengers and freight.”
