Basically, any of the services via Edgware Road would have to be C

I'm not sure of the reasons.

UIVMM it's because C stock can't go as fast as D stock, so would
cause
delays.

I always thought it was a gauging issue at Dagenham East - some part of
the C stock kept getting smacked by a platform edging stone or railing.
I've seen C stock DMs with Upminster on their dest. blinds, so they've
definitely been there in the past.
