I’ve heard and seen on twitter that Network Rail are operating two return London Liverpool Street - Peterborough via Cambridge this Saturday and Sunday 18/19 February, due to ECML closed from St Neots to Kings Cross.
Bit unusual in that they have only gone into RTT last night, and won’t have been shown in any schedules that passengers have booked this weekend.
