Fares for the highly anticipated Elizabeth Line will match the pay-as-you-go fares of existing Transport for London (TfL) services across most of the capital.
TfL and mayor Sadiq Khan confirmed the fares for the £14.8bn project would be the same when travelling within zones one to six, however fares will differ if travelling outside of these zones.
Customers wishing to make the journey to Heathrow will pay more to travel on Crossrail than on the Piccadilly Line. Travelling between the airport and zone 1 in central London at peak times will cost £12.10 - £7 more than the same journey on the Piccadilly line.
A peak Crossrail ticket for Paddington to Heathrow fare will cost £10.20 - less than half the cost of the £27 standard fare on the 15-minute Heathrow Express shuttle, though the Crossrail journey time is about 10 minutes longer.
The Crossrail project will serve 41 stations and stretch across more than 60 miles from Reading and Heathrow in the west through tunnels in central London to Shenfield and Abbey Wood in the east. It will be known as the Elizabeth Line, when the tunnels under central London open.
