I saw this too when I went past East Ham depot. I'm 99.9% sure I also saw Diamond Jubilee vinyls on 357227 as well.Have just seen 2 c2c 357 units applied with large Union flags and Diamond Jubilee symbols.

Sometimes I wish these boards had a "like" button like facebook...A Stratford silver roof...? On an ELECTRIC loco...? That's as wrong as a very wrong thing. No, no, no, no, no. Stratford is a DIESEL depot. As nice as 90009 looks it is an abomination; an offence against nature.
