Well this afternoon has been interesting.
With almost no notice, Meridian Bus seem to have suspended their 5 day old route 321!

No explanation given so far, and their website has no mention of the route at all. Rumours on Facebook range from a engineer that’s phoned in sick to the Redline service 21 not charging fares for this week.

MK Council are advising passengers on the City Centre to Olney section to catch the 21. Passengers for the Buckingham end of the route I’d suggest either the X5 or 32.
