I remember once seeing Service 8 Darlington - Spennymoor running over 50 minutes late once due to roadworks at Beaumont Hill in Darlington.
Also remember once getting Service 7 for Framwellgate Moor and The Honest Lawyer was flooded and it took us 1 hour 15 minutes to get to the Coach and Horses then we had to turn round at the roundabout and it took us about 20 minutes to get back to Thinford roundabout. After over 90 minutes on a horrid Dart I decided I'd had enough, so I walked to Ferryhill Market Place and caught Service 35 to Bishop Auckland which then changed to the 5/5A to Newton Aycliffe.
