For whatever reason, the Starting Signal into a DLB section is always
a Two position signal.

Somerton is an island of 3 Position Signalling, but the Starting
Signal is again 2P.  (And the Home off the Upfield Line, for that
matter).

The last Up Home, protecting the Junction of the Albion line may
disappear, it's always seemed a bit unneccessary to me.  E 573 will
need a illuminated '65' indicator, and Dwarfs seem to have a difficult
time surviving resignalling. |-)

Knowing the abolitionists out there, I wouldn't be surprised if they
go.
