Alas it hasn't made it into the Journey planner and there doesn't seem to be any intermediate times.Not sure how its "slipped" as the original given date was 11th January - they've probably only updated the systems to New Years Eve and have now got a more coherent plan.
Apparently the bus timetable has been 'erratic' at best, but its recently been updated on NRE with extra info on bus times: https://www.nationalrail.co.uk/service_disruptions/262979.aspx
I appricate this isn't planned but they must have some idea of how long it takes for the bus to reach places, based on buses running during engineering works.
Someone has managed to at least cancel the trains from the system so they show up.
Is the ability not to add in the bus times due to not enough staff working? Be it due to holidays or simply covid-19 related sickness or self isolation?
