Are Oyster60+ valid between Liverpool Street and Tottenham Hale on Stansted Express.
If travelling to Harlow, Bishop Stortford or Stansted Airport can Oyster 60+ be used with a Boundary Zone 6 ticket on Stansted Express?
Doesn’t distinguish the Stansted Express from any other NR service so I would say yes. I tried to buy a ticket on the line to Cambridge North from the boundary of zone 6, but found it much cheaper to book it from Enfield Lock (last valid station) instead. I don’t know why this should be.
