Reply To: Tube Challenge – all stations in one day

Coincidentally, I’ve just seen this on IanVisits:
“TfL also continues to consider a separate proposal to generate additional income by withdrawing from the Travelcard Agreement. This would require the support of the Government and the Train Operating Companies due to the impact on Travelcard usage in London, especially for customers travelling from outside London where PAYG is not available.”

Transport for London fares to rise by 5.9% from March

If Travelcards go then something like the Tube Challenge becomes either impossible or very expensive.
