Oh you've wrecked the criteria! I was going to suggest St Ann's Road
/ Seven Sisters Road on the GOBLIN as well as Forest Road, Winchester
Road and Chingford Hatch on the Chingford - Liverpool St line. These
extra stations would hugely increase the catchment areas for these
lines even though I recognise they would slow overall journey times.

You could decrease journey times to Chingford by builiding a new terminus on
the south side of Kings Road. This new station would have a catchment area
which was 100% houses, whereas the current station's catchment area is 70%
trees. You could also make a fortune by building houses on the line north of
Kings Road.

If Network Rail were feeling suitably insane they could build an
interchange station at Ferry Lane Estate where the GOBLIN cross the
Lea Valley line via Tottenham Hale. Obviously not every Lea Valley
train could stop as it's reduce line capacity but the locals to
Hertford East could possibly provide a half decent service.

Since the Goblin largely parallels the Victoria Line, with which the line
interchanges at Tottenham Hale, I don't see this one stacking up.

A station at Pickett's Lock was proposed for a while in connection with the
2005 World Athletics Championships, but it would also be the nearest station
for a fair number of houses.

An Enfield Highway station on Carterhatch Lane.

Station ideas which have been bounced around by official bodies include
Wingletye Lane
Little Ilford
Ventnor Road, Sutton
Brent Cross Thameslink
"Great West Road" between Kew Bridge and Brentford
Mitre Bridge, North Pole, Stamford Bridge (Fulham Road), and Battersea High
Street on the WLL
Old Oak on the NLL
