They seem to be sticking with a 150 on a Sunday3 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.
Oops! Forgot Sunday existed, it's clearly a relevant day of the week on my calendarThey seem to be sticking with a 150 on a Sunday
Wasn't that the coryton line? I dont think 153s ever did the bay line.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.
153s used to run the Cardiff Bay to Queen Street shuttle back when it was every 12 minutes. It swapped over to 150s when they reduced the frequency and extended half hourly up to Pontypridd.Wasn't that the coryton line? I dont think 153s ever did the bay line.
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...
Wonder if we'll see one be used on the TAM lines before the December timetable!
I used to commute on it mate I can promise you it was 153sWasn't that the coryton line? I dont think 153s ever did the bay line.
Well if the full complement needed for the Pontypridd to Bay service will be in operation on Wednesday then I’d say it’s not at all unlikely that one or two will venture further north by the autumn solstice.Let's not forget that the most recent PR video from TfW said that the 398s would be rolled out to the Treherbert, Aberdare and Merthyr lines "later this summer". The contributor you refer to said that this was unlikely, and that it was more likely to be 2027. He has not yet been proved wrong.
Of course 153s are not cleared north of Radyr153s used to run the Cardiff Bay to Queen Street shuttle back when it was every 12 minutes. It swapped over to 150s when they reduced the frequency and extended half hourly up to Pontypridd.

RTT supports this. Three non-test movements out of the depot from what I can see, one at 0540, one at 0552 and one at 0617.Have had word to say there should be 3x 398s out from Wednesday
Looks like one is due out this Sunday, but I said that last week and it didn't happen. Obviously plans changed.They seem to be sticking with a 150 on a Sunday
If all goes well I'm sure we will and a few more as time goes on, it's clearly intended to continue as a gradual process rather than a "big bang", lessons have been learned! TfW's Operations Manager likes to call the resulting moves of other units "The Grand Cascade", make what you will of that....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...)

Thanks for letting us know021 is indeed a newbie in service

I'm only counting the ones that carry passengers as being 'in service'.026 is out testing today which I think is also a new unit?
Indeed it appears to have been pulled at around 1500 for traction issues, but has come back just before 2000 to cover for 398017 which itself had only managed a return from Taffs Well to Pontypridd, having been sent out to cover for 398021...Was out today on 031, which the guard said was having some "traction issues" (whatever that means)
I was lucky then, as my second attempt to get to Wales to sample a 398 (and a 756, another new class for me) got off, just like the first attempt, with meltdown on the District and Overground at Richmond, and the Overground also at Clapham Junction. But unlike my oprevoius attempt, when i never got further than Paddington, this time everthing else went to plan - in fact better, as I was also able to compare the 756 with a 231, and get a proper ride on a 197 (my only previous attempt having got from Man Picc to Oxford Road and then breaking down).Rather a poor day today with the 398s unfortunately. If I'm reading it right:

Excellent! Let's hope they last the dayThree units out today, 017, 029 and 031.
