Strike contingency plan Walthamstow to Heathrow

Maybe OverGround train service from Blackhorse Road to Gospel Oak,
then Overground train Service Gospel Oak to Richmond.
Then train from Richmond to Feltham, from Feltham 285 bus for
terminals 1,2,3, or 490 bus for terminal 5.
Sounds great as a day out, but the OP's got a plane to catch!!
