Engineering work is taking place between Welwyn Garden City and Hitchin, closing all lines late on Saturday night and early on Sunday morning.
As a result, buses will replace trains between Welwyn Garden City and Letchworth Garden City / Peterborough, and between Hertford North and Letchworth Garden City.
Customers travelling on the 23:11 Horsham to Finsbury Park (Saturday) service are advised to change at Finsbury Park for a train to Welwyn Garden City, then a replacement bus towards Peterborough.
