Tube and tram could extend into Sutton
Plans to 'stretch' the Northern Line and build a new station in Merton
have been included in a series of ambitious transport proposals
compiled by the leaders of south London councils.

From looking at the map it seems an obvious link - but if so why has
this not been done before. IIRC the southern end of the Northern line
gets quite congested - Is this because the stations are too small, the
train frequency too low or the peak hour passenger demand too great.

IIRC the idea of extending the Northern Line southwards has been suggested a
number of times before. It didn't make it into the 1972 London Rail Study so
the economic case must have been poor at that time. However times change and
congestion now is a lot worse than it was then.
