End of next year, though I'm not sure about access to the circle line.

3. Take this to Earl's Court where one can change to a Heathrow-bound
Piccadilly line train using the lifts.

Surely it's easier to do a cross platform change to a westbound
District to get the Piccadilly cross-platform at Baron's Court or
Hammersmith?

Coming back, the route involves switching at two points to end up on an
anti-clockwise circle line to Moorgate, from which one can at present
get on the level to a train to Luton/Bedford at certain times of the
day. *Unfortunately this possibility will soon vanish forever. After
this things get a lot more complicated...

Get a southbound Thameslink at Farringdon, and use the ramps at London
Bridge to get a northbound?

(alternatively, there are lifts from SSL to Thameslink at St P, if the
walk between them isn't too much)
