When was the last time that Arriva ran buses in to Cambridgeshire? I completely forget what but I am certain they used to have something that ran in to Cambridgeshire? I know in the 2000s and 2010s they used to have a few routes to Royston which is almost Cambridgeshire but not quite. I think possibly Stevenage to Hitchin to Royston and possibly Hertford to Buntingford to Royston if i remember right. These ran right by the border but did not actually cross. However I am pretty sure they had one service that diverted via Ashwell & Morden station meaning it actually crossed the border and entered in to Cambridgeshire. But my memory is not the best and i am struggling to find anything to confirm? Can anyone confirm when Arriva last ran anything which crossed the border in to Cambridgeshire and which route this was?
