Train passangers in Letchworth and Royston will be affected by engineering work this bank holiday weekend.
From 10pm tonight Shepreth level crossing in Station Road will be closed so that engineers can carry out an upgrade.
Tomorrow, buses will replace trains running between Letchworth and Cambridge. All London to Cambridge services will start to terminate at Letchworth, with a train shuttle service also operating between Cambridge and Kings Lynn.
Passengers should check before they travel at nationalrail.co.uk.
