I have to dispute a couple of those, Joe Strummer... just from my old neck of the woods
The 145 has been extended from Redbridge Station (its post-1986 terminus) on two occasions post-1987 (and another extension within Redbridge was announced and advertised, but was not introduced), first to Leytonstone Green Man, and then to Leytonstone Station. And the destinations at Dagenham have altered since then as well (was New Road/Fords Main Works, now Asda - which wasn't even there in 1987)
The 175 has had a rerouting recently in Romford to serve the new hospital there.
Can't argue with the others listed that I know though!
