WTTs, and the odd TTN, are published to Working Timetables (WTT) - Transport for London
Only in PDF, which is human-readable (just about!), but impossible to convert to anything more computer-friendly for picking apart in code.
But the PDs do contain the tantelising declaration:
"A digital version of this Notice can be found on the Establishment Planning Sharepoint site at https [colonslashslash] transportforlondon [dot] sharepoint [dot] com/sites/EPTimetables/
Unfortunately, that seems to require a (TfL) Sharepoint logon to access.
What ‘digital’ format is on the Sharepoint?
I’d love to get PICC timetable data including Train no/Trip no and time at key stations (as appears in the PDF WTTs). Might that be possible?
The SharePoint site hosts the same PDF files that are available on the link you provided. These PDFs are often printed out as physical copies. So the reference to the SharePoint site informs colleagues of how they may obtain the original PDFs.
I would love to see this happen some day, as some may be aware I worked on a project called “TubeTracker” to make use of these detailed timetables in a website similar to Realtime Trains. It’s been closed and archived due to the difficulty in obtaining the CUF files, but if they start getting regularly published then I would certainly consider opening the website back up.
The CUF timetables include lots of very useful information when compared to the journey planner TransXChange files, like running numbers, trip numbers, non-passenger trips, and all locations rather than only the stations. Certainly beats trying to OCR or parse PDF files too!
When combined with the train running information in the TrackerNet APIs, you can achieve quite a lot with this data! I happened to do a talk about this at EMF 2024, but unfortunately there is no recording available.
