We saw today that there will be disruption on parts of the Northern Line over Easter, basically no service from Friday through to Monday. Camden Town and Archway will be closed, there will be a replacement bus service, Service B (King’s Cross to Archway – see second pic for details), but it is very inconvenient for travel to our Easter workshops, as Archway is the nearest underground station. https://tfl.gov.uk/status-updates/planned-works-calendar and https://tfl.gov.uk/tube-dlr-overground/status/
Here are the posters for information.
