Yesterday TfL released details of the fares to be charged on the Elizabeth Line when it starts operating at the end of this year. They also confirmed fares for the second TfL Rail line from May 20th between Paddington and Heathrow. This will become part of the Elizabeth line later on.
The big news is that Heathrow (TfL Rail) will be joining Heathrow (LU) in zone 6. This means that travelcards will be valid as will all other TfL concessions (zip cards, freedom passes, etc). The downside is that there will still be a premium to be paid for single fares to/from Heathrow (TfL Rail), but Oyster and contactless capping at the zone 6 level will limit the effect on return journeys and indeed on other travel within the zones that day once in London.
As for the rest of the line, fares in the central area will be the same as normal Underground fares. This will extend westwards as far as Hayes & Harlington and West Drayton. To the east Whitechapel and Canary Wharf are mentioned as being standard LU fares, but the press release is silent on further out. Currently the fares to Harold Wood are the same in the peak but a bit more expensive off-peak. It remains to be seen what fares will apply to/from Woolwich and Abbey Wood.
I’ll add more details on the actual fares in the coming weeks.
