Tomorrow will be the opposite whereas a 398 is booked to shuttle on the Bay line the entire day.No 398s today because of engineering works closing the line north of Radyr - seems to be just a single 150 shuttle on the Bay branch.
I wonder how close are we to three 398s out in passenger service on one day ?.Tomorrow will be the opposite whereas a 398 is booked to shuttle on the Bay line the entire day.
That must mean that the wires are live.Tomorrow will be the opposite whereas a 398 is booked to shuttle on the Bay line the entire day.

I don't think they've published anything to even acknowledge they're in passenger service yet. I think the question is how many units are needed to run the treherbert diagrams? I suspect that'll be the route that switches first, given they want to extend the pontypridd service up there too.Has TfW updated its public position on when the 398s will be introduced to the Treherbert, Aberdare and Merthyr lines? In May, they said that it would be "later this summer", but that now looks very unlikely.
Nice to see them finally using the wires down there.398030 arriving at the bay yesterday morning… couldn’t hear the pantograph retract but was down at Queen Street where I got off…

How are they getting to and from Taffs Well depot if the line is closed beyond Radyr?
Presumably it's actually closed somewhere north of Taffs Well but Radyr is a more appropriate place to terminate passenger services.
I was wondering the same thing earlier and looked at Traksy but there are no closures shown which is a little surprising.

They do seem to be doing a lot of testing on NR infrastructure lately, likely due to the TAM closure but good to see nonetheless.Happened to see 398016 and 023 under test at Cardiff central today. https://www.realtimetrains.co.uk/service/gb-nr:V24912/2026-08-12/detailed#allox_id=1
Fantastic. Both units running the entire day too.Looks like we’re back to 2x 398s in service again after last week’s engineering works. 398028 and 398029 are both out today on the Pontypridd to Cardiff Bay service.
Great to hear.Have had word to say there should be 3x 398s out from Wednesday
Weird that the moment they start rolling out in larger numbers with few failures that said contributor who said so many different things about the units and how awful they would be has vanished. Good to see them rolling out in bigger numbers and hopefully that means a positive outlook for December when a significantly larger workload is required. It just means all the fleets can move to their retrospective lines (i.e. 231s Mainline, 756s on the Rhymney line, 197s off Maesteg/Ebbw/Cheltenham to elsewhere...)Great to hear.
Given all the doom and gloom we were hearing about the units from one contributor (who has gone strangely quiet for the last month), it's really positive that there seems to be slow but steady progress in rolling the units out.
The job lot of portable showers must have been deliveredGreat to hear.

3 units. Today 2 of the diagrams are 398s and one is a 150. If a 3rd 398 is sent out that'll mark the end of 150s on the Cardiff Bay branch, assuming none need to be called in to help.How many units does Pontypridd - Bay (including the shuttling) require?
Mind you, when I left Cardiff (lived there 2021-2024), they weren’t regular on the line anyway. Used to be a 153/9 Mon-Sat and a 150 on Sundays.3 units. Today 2 of the diagrams are 398s and one is a 150. If a 3rd 398 is sent out that'll mark the end of 150s on the Cardiff Bay branch, assuming none need to be called in to help.
