Licence note
TfL's transport-data-service terms page says: "These licence terms and conditions apply to TfL’s free transport data service and are based on version 2.0 of the Open Government Licence with specific amendments for Transport for London (the “Licence”)." Recorded as Custom rather than OGL-UK-2.0 because of TfL's stated amendments.
Attribution
Required: "Acknowledge TfL as the source of the Information by including the following attribution statement ‘Powered by TfL Open Data’" (quoted from the licence terms). The same licence terms also require: "Acknowledge that this Information contains Ordnance Survey derived data by including the following attribution statement: ‘Contains OS data © Crown copyright and database rights 2016’ and Geomni UK Map data © and database rights [2019]".
