My colleagues in the PSV Circle have reported a replacement 7513 in the form of LJ61 CHG, formerly Arriva London North T203, a classic Enviro 400. Presuming it is having the centre door removed before it comes north to Durham/Teesside.

Wonder if a replacement for 7508 is on the cards too. Can't remember if that was an accident victim as well, or just past its best !
