(20 Oct 2014, 4:21 pm)Kuyoyo wrote National Express news - due to issues with Yourbus (a high number of VORs reported, resulting in operation recently by Parks of Hamilton), Go North East will temporary taking on operation of the 591/594 between London and Edinburgh. Owing to the overnight nature of the 594, it seems they will be worked by ex-Yourbus B9Rs 7116 (FJ60 KVM) and 7118 (FJ60 KVP) as these two have crew seats.

EDIT: Sorry, only just seen that - apparently happened a fornight ago and since been replaced by Bruces of Salburgh
And GNE have reverted to operating the 591/594 - as shown by 7112 arriving in Newcastle on Friday afternoon on the 1555 591 to Edinburgh arriving over half an hour late (arrival in Newcastle was meant to be 1545).
