(07 Jun 2015, 1:08 pm)MrFozz 722/723 was that the service jointly operated by United/Arriva and Northern???
Used to use it a lot when I lived in Durham and the 724 when I lived in Spennymanure and Bishop Auckland all the time 
Yes it was.
Think it stopped serving Newcastle around 2003 with Arriva operating it between Darlington and Durham (Framwellgate Moor?) and GNE Durham and Newcastle. There has been loads of changes since then.
Was quite fun actually having two operators doing the same service but was annoying at the same time as I don't think GNE accepted Arriva tickets. Think my first rides on GNE Prestige's were on evening 723s.
