Hi, I have a railcard on an Oyster card so would like to avoid paying the peak cap so I am able to get cheaper fares. I will be flying into Heathrow T5, but on the weekend I arrive the Piccadilly line is partially closed in the city. To avoid the peak fare going straight to zone 1, am I right that I’m able to get the Elizabeth Line to Ealing Broadway and tap out, then return tap in again and get the Central or Elizabeth into zone 1, and will only be charged off-peak? (Will be after 9.30 am)
