All rhymney services are back to serving penarth from December.

Pre-Covid, whilst daytime services to & from Penarth originated from Bargoed & Rhymney, some evening services came from & went back to other Valleys. On Sundays, some services to & from Barry went to & came from Rhymney.All rhymney services are back to serving penarth from December.

From 13 December, all services to & from Bargoed & Rhymney will go to Cardiff Central or Penarth only, 7 days a week. Hopefully this means by early 2021 we'll see a full deployment of 769s all day every day on Rhymney - Penarth services to finally see off the Pacers.
If my calculations are correct, the whole Penarth to Bargoed and Rhymney service requires six units. You raise a good point about route knowledge. Maybe Cardiff and Treherbert will learn 769s as well.Only 3 x 769s would be required to work exclusively between Rhymney and Penarth but Bargoed services are also running to Penarth so a chance for more there. If only Rhymney drivers are going to work 769s there would be problems in Valleys crews, who work universally in the Valleys, maintaining route knowledge to Rhymney in the case of Cardiff and Treherbert crews.

I think that TFW have been trying to avoid extensive training but we can always wait and see. Things will change on introduction of the Metro, though
Why would Treherbert drivers need to learn 769s when the 769s are staying confined to Rhymney - Penarth? Plus 769s will need to be cleared to Pontypridd and Treherbert. Extra expense of crew training and clearing 769s for other routes is not a luxury that TfW Rail has.If my calculations are correct, the whole Penarth to Bargoed and Rhymney service requires six units.

Don’t Treherbert (and Cardiff Valleys) crews also work Rhymey services?
In order for them to retain route knowledge to Rhymney. Either Cardiff and Treherbert need to learn 769s or at least one diagram on the Rhymney line needs to be diagrammed 150s (which reduces the number of Pacers that can be withdrawn). Otherwise their route knowledge will lapse. Rhymney is only a small crew depot so if someone goes sick and the other depots cannot cover, then potentially all the workings on that diagram will be cancelled.Why would Treherbert drivers need to learn 769s when the 769s are staying confined to Rhymney - Penarth?

If Rhymney was a mix of 769s and 153s would the 153 diagram(s) be sufficient to allow Cardiff and Treherbert crews to retain route knowledge to Rhymney or do Treherbert only sign 150s and Pacers? Also, would the route-knowledge retention diagram being 153s affect the ability to withdraw Pacers any more/less than using 150s on that diagram?In order for them to retain route knowledge to Rhymney.

As I understand, any non-769 unit on the Rhymney branch would affect the number of pacers that can be withdrawn, because taking a 150 or a 153 away from somewhere else increases the likelihood of a pacer having to stay in service to cover the redundancy.If Rhymney was a mix of 769s and 153s would the 153 diagram(s) be sufficient to allow Cardiff and Treherbert crews to retain route knowledge to Rhymney or do Treherbert only sign 150s and Pacers?

Pacers wouldn't come into the equation.
Would anyone be so kind as to post the current full diagram for the 769 please i fancey a stab at these next week

Exactly this. Five 769s will replace five Pacer+something else (usually a 153) combinations. The five Pacers go in the bin. Let's assume they can find another 153 to make it up to six, so they have three pairs of 153s that can work in West Wales and replace three 150s. So that's three more Pacers in the bin. The only way to bin more Pacers is to run shorter trains.As I understand, any non-769 unit on the Rhymney branch would affect the number of pacers that can be withdrawn, because taking a 150 or a 153 away from somewhere else increases the likelihood of a pacer having to stay in service to cover the redundancy.
The new timetable between Rhymney and Penarth will have 6 diagrams by the looks of things so there will have to be some non-769 operated services.As I understand, any non-769 unit on the Rhymney branch would affect the number of pacers that can be withdrawn, because taking a 150 or a 153 away from somewhere else increases the likelihood of a pacer having to stay in service to cover the redundancy.
There will be 9 units ultimately though?The new timetable between Rhymney and Penarth will have 6 diagrams by the looks of things so there will have to be some non-769 operated services.
Correct - just pointing out that initially it’s likely that it won’t be possible to be all Class 769.There will be 9 units ultimately though?
Yes nine units. They can't run anywhere other than Penarth to Rhymney so maximum of six in service per day until the service increases again.There will be 9 units ultimately though?
Can they definitely only run Penarth - Rhymney? I know they can't go on City line because they're too long or Barry - Bridgend because that's mainline crews, but is there anything other then getting them cleared stopping them from going up the Taff Valley and/or Barry Island?Yes nine units. They can't run anywhere other than Penarth to Rhymney so maximum of six in service per day until the service increases again.
The bodyshells are very similar to class 150s so clearing them for the other routes could be quite easy. I think it was only ever planned for seven of the nine units to be diagrammed. That could be achieved if they can run the Cardiff Bay to Caerphilly shuttle.Can they definitely only run Penarth - Rhymney?

Just thinking it through; I don't think Rhymney depot is large enough to staff all the Rhymney valley services by itself - so if they do want to run 6 diagrams all day they may well need to expand the training to other depots. I could be wrong though, just a hunch.
