(22 Jul 2019, 3:55 pm)Boggle wrote Bit of a mix up for the 16:50 X21 from Newcastle to Durham tonight. 6139 turned up from Chester (as normal for school holidays) closely followed by 6033 from Riverside (as normal on school days), both for the same run. A lack of communication somewhere there.
Most bizarrely, both buses ran the service in tandem, 6033 following 6139 entirely empty.
