I wish they would better space out the Durham bound 21s in the evenings, there's points you have to wait up to 45 minutes for one to Durham but there's two Chester terminating journeys in that time at points, the 2020 X12 off Newcastle ends up picking the people who have got bored of waiting ages for the 21 towards the Chester/Durham end of the route quite often.
