19158-63/93 are bound for Stagecoach South. (thanks to Kuyoyo)
ALX400's are for SLATYFORD (this has just been posted in the last 24 hours)

This information has already been posted, for the last time NO Enviro 400's are staying at Stockton for service, although you may find E400's around Teesside (I saw 19158 driving up Portrack) not in service.
