Hi all, I'm planning a route for an alternative tube challenge (Roads, Streets & Lanes) when I noticed that the WTT and timetables listed on the TfL Timetables page rarely match up. Both appear to agree on the initial departure time from the first station of each trip, however gradually de-sync throughout the route.
I'm assuming this is either due to some effect of the problems with central line trains or some change to a temporary speed restriction (or very possibly my own inability to correctly interpret the WTT)
Regardless, for the purposes of tube challenges, which one is generally more accurate? I'm specifically looking at the Monday-Thursday 10:20 Shepard's Bush to 10:31 Hanger Lane service listed on the TfL website - which appears to be roughly 2 minutes later on the WTT.
