My "solution" would be to fit aircon to A, C and D Stock and order extra C Stock. The following lines should re-open (with no intermediate stations):
- Finsbury Park to East Finchley
- the GE connection to Leyton
- Goblin - Thameslink connector
Then for July and August the following service pattern should operate:
Tube Lines
BAKERLOO LINE
No service beyond Queen's Park, except for depot journeys
CENTRAL LINE
No service East of Liverpool St - Bethnal Green Station closed
NORTHERN LINE
Edgware / Mill Hill E branches only at N end.
PICCADILLY LINE
All trains to Heathrow
DRAIN
normal, um, errr, good service
VICTORIA LINE
normal, um, errr, good service
JUBILEE LINE
No service beyond West Hampstead

Chesham Shuttle
Baker St - Watford Semi-Fast

Rayner's La - Edgware Rd
Ealing Broadway - Plaistow/Barking

Wimbledon - Edgware Rd
