After a final look today at the new concrete and steel bases springing
up everywhere on the District/NLL road to Richmond, I'm convinced now
that NR intends to resignal the whole lot during the Easter Possession.

Judging from the positioning and number of bases I'm guessing that
4-aspect MAS (with the occassional repeater) is going in, at least on
the up line. Having asked around, some District Line T/Ops say that the
line is indeed being resignalled and that the signal cabin at Richmond
may be abolished. Is any more information available?
