"DO" and "WB" Interlockings in Roanoke

[NW Mailing List]

In 1949 the N&W built two new interlockings in the Norfolk area: "WB" at
West Roanoke and "DO" at ?  I am assuming that the controlled switches
replaced hand throws at both locations.  Were new buildings built to contain
the interlocking machines and operators?  One story or two?  Or were
one/both controlled from another location?  Any info about these two would
be helpful.
