From Monday 23rd March, London Overground will have the following changes.
Dalston to New Cross = Cancelled completely.
Highbury & Islington to West Croydon = Cancelled completely.
Services will be 4tph Highbury & Islington to Crystal Palace and 4tph Highhbury & Islington to Clapham Junction.
IF staff levels drop below a certain level due to being put in isolation, then it may be required to drop to 2tph for each. Prepare for any changes. As such, there is no plan for any LO station to close as they have on London Underground.
Be aware, that staff levels does not mean just drivers, but also managers, station staff, controllers, signallers, maintenance, cleaners etc. The railway is a massive operation requiring many people to keep it running. If you encounter a staff member whilst travelling, please take a deep breath before you yell at them for lack of service. They are there helping you to travel whilst your loved ones are happy and self-quarantined.
