But RTT shows this as cancelled for an "excluded reason" today (8th October)

What I am looking at ran Thursday night (08/10/2026) BUT actually all after midnight so actually in the early ours of Friday morning 09/10/2026.

I see 3Q50 from Taffs Well to Treherbert ran
Then 3Q51, 3Q52, 3Q53, 3Q54, 3Q55 & 3Q56 all ran (little return trips out to Llwynypia and back to Treherbert.
tHEN 3Q57 back to Taffs Well cancelled.

So perhaps more test runs of it tonight ?.

Or a different 398 tonight and 398021 is left at Treherbert after a successful set of tests ?.

Is there something special about Treherbert to/from Llwynypia ?.
(my first assumption was its a convenient stretch that can be left open to traffic overnight but, alternatively, is/was there an issue for 398s on that stretch for instance).
