Yes, sadly the two projects are being driven by different areas with different aims. The contactless extensions are a DfT desired project aimed at making paying for rail travel easier and cutting back on paper tickets. The withdrawl from the day travelcard scheme is being driven by the Mayor as part of his requirement to make savings such that TfL becomes self funding. It does ultimately come down to the DfT, but there is no joined up thinking with this government, so we have to make do with what we get.
