Latest news from the Bluebell's website states that (providing nothing goes wrong!) 'Beachy Head' should be moved out of Atlantic House & into the Loco Maintenance Shed and/or the Loco Works to complete painting & commissioning this Autumn. Entry into traffic is then expected to be at some time between Easter & early summer 2024.
