Thanks for this. Do we know what extras there are in West Wales on Sundays?
During the week we have 2 extra Carmthen-Tenby shuttles for the summer timetable which is good as both units operating these were just sat at Carmarthen anyway.

Basically an earlier start to service West of Swansea. I don't have Summer 2024 to hand, but they look similar to the Summer 2020 (planned not actual) service, so may be PR spin rather than a significant development
It's a bit more than that for the high season during August to be fair.
Aside from these there are some retimed services.
