Although the WTT set was updated overnight, it appears that it does not reflect the actual service changes made at the weekend. For example, the files for the 497 carry a January 2020 date and do not reflect the extension to Dagnam Park Square. Others that should, I believe, be there include the 52 and 302 (both service reductions) and the 217 (end of widened headways).
The Datastore zip file had not been updated when I last looked about half an hour ago. This might have nothing to do with the WTT issues - but then again it might, as I had heard rumours of some sort of system change within TfL. Is there anything that would be useful for users to know at this point and - if there is a system change - will outputs look the same after the change? If not early warning would be helpful. I did comment some months ago about some new look WTTs which had escaped into the wild and the intense, possibly terminal, impact on what I do with them.
This is (I think) independent of the switch at some point to a new version of TransXChange for the Datastore zip file, which I don’t think will change much for the end user.
