I just noticed that Dalston Kingsland has two roundels in the street
bearing the station name. I remember seeing an old external photo of
Oakwood or Southgate station with a station name roundel over a seat in
the 1930s, but I believe that was replaced with an UndergrounD roundel
shortly after the station opened. I'm not aware of any newer ones. I'm
wondering why here... could it be to alert people to the fact that this
is not Dalston Junction? Is it a new feature since DJ opened? Are there
any other station name roundels in the street?
