Class 756 can actually continue the journey onwards on diesel / battery power if the pantograph system were to break down. From what I can see looks like they are using neutral sections before the bridges which means power off then after the neutral section resume power
Wonderful video! Can tell it took a lot of time and effort. I work on the CVL project at the moment as an apprentice, so its cool to see videos of things underway :)
Probably the pacer was better to travel on at least they had a toilet which these tram things got no toilet great travelling from Merthyr /treherbert with a hour journey time
Overhead Line Equipment is one of the best inventions introduced on the railways, saving lives of permanent way workers, people and animals in the event of live rails contact, providing much higher voltages to be apllied in order to operate much powerful traction and making the electric suplying system more efficient. But...is always a but and aesthetically it looks terrible due to its cage effect obstructing fantastic views that were once before electrification and are very prone to cause long disruptions during adverse weather, pantographs malfunction or vandalism for instance.
Electrification ready for the Class 756 and Class 398. Perhaps Transport for Wales could also inherit the Class 379 Electrostars to operate on some of the newly electrified lines and hopefully Network Rail should electrify to Swansea.
@@MervynPartin Yeah Class 365 cascaded to TfW with the electrification to Swansea if that ever happens. But unfortunatly the Class 365s are now been scrapped :(
Theresa May scrapped the proposed electrification to Swansea. Politicians need to keep their hands off the railways and let them get on with the necessary work
The cable troughs next to the track are for signalling cables, not high voltage. All the high voltage is on top of the masts well away from people and animals. Guessing the interlocking/signalling is so old that it will be affected by 25kV 50Hz power using the rails as the return line, so they will most likely be installing new, modern electronic interlocking as well.
The plastic cable troughing set down into the ballast is for signalling The steel trunking that is elevated off the ground on posts is (to my knowledge at least) for containing 25kv power supply cables for the overhead traction supply. the trunking now bares "Danger 25000 VOLTS" text.
I noticed that the city line isn't shown as being electricifyed maybe this is because the line is relatively short and the tram trains can run on Battery power on that line?
From what I've heard talking to an Engineer from TFW, Battery power is only for use on really short sections, and my guess is that the City Line would be way too long and have too many stops to work on batteries alone, so I'm guessing the line will be electrified in the near future. From 4:18 in the video, those shots of all the cable troughing stacked up beside the railway is actually from the city line, so the start of electrification work may already be underway. There is conflicting information online that says that the bay shuttle might be battery power only, so I haven't a clue with that. either way, any new large developments and I'll make a video on here about them!
@@WalesRails yeah they did say something about the Bay Line being powered by Battery on the street running Parts but that mite be future Sections after Flouish Station (stop) continuing towards exetter!
@@WalesRails Quote "In Stadler Citylink Metro Vehicles, estimated that if a tram-train had a 50 kWh battery, this would have a range of five miles, which would take the vehicle from Queen Street to The Flourish and back" so maybe that would be enough for a one way trip from Radyr to the wires at Queen Street charging up at queen Street and continuing to Coryton and back there was talk of electrifying the Coryton line and now Tfwrail are planning to fully electrifying to Rhymny line! what would be even better if they extend the Coryton line (loop) back to Radyr continuing along to old Cardiff Railway to a new M4 Parkway station!
The CAF 197s will operate on regional routes in and out of Wales and up to North and West Wales from Cardiff. They will not operate on any part of the network that comes under the "South Wales Metro" project, so not on any of the bits being electrified or that I talk about in this video. The South Wales Metro will be served exclusively by Stadler Citylinks and FLIRTs Also, even if 197s did service partially electrified areas, they are DMUs with Hydrostatic transmissions, so they are incredibly difficult and probably always impractical to convert to overhead electric.
Yeah but it makes a lot of sense on the Merthyr & Rhondda line, the bit that frustrates me is how the Vale of Glamorgan line, as well as the route up to Maesteg and Ebbw Vale isn't being electrified at all despite being serviced by overhead-electric capable trains 😒
It was the intention with the Class 398 citylink tram-trains that half will terminate at Cardiff Central and the other half will bypass Central and head on down to the bay where the current Butetown branch embankment would be removed and replaced with a tram-style segregated, but at grade, right of way and then on-street running to outside Roald Dahl Plass, as this is a light rail conversion and extension, on board toilets are not possible due to the nature of the tram-train rolling stock in being narrower and lower to the ground (no space for toilet waste or supply tanks) TfW's solution to this is to install toilet facilities at a number of stations along the line. In regards to the 398s having onboard batteries, yes they do however they can only manage a very small distance on battery power and from what I can gather, this will only be used for primary traction supposedly temporarily on the 1 mile long butetown branch line (Cardiff Queen Street > Cardiff Bay).

Thank you very much, that's so cool someone working on the project has seen one of my videos!
any insight you could give on the project?
Looking forward to these new trains, pacers to electric trains in like 5 years!
Probably the pacer was better to travel on at least they had a toilet which these tram things got no toilet great travelling from Merthyr /treherbert with a hour journey time
Well done hope your feeling better.
Aww Thank you :)

Is that a farewell to all trains on this line for the future being? Thank you for the update video.

The 365s were pretty good trains, too.
All the Swansea money has been diverted to Crossrail and HS2- more knighthoods to be won for that..

the City line is just over 4 miles long! depending on the gradient up to Radyr and Passenger load it mite possible?

@@don1estelle I'm surprised that wasn't done from the off electrifying the whole valleys network tram trains can cover all of it then
I wonder if the class 197s will be turned into 397s and given electric equipment.

@@WalesRails I see,
@@WalesRails what is hydrostatic transmission?
By 2030 saying Crewe and Chester and from Warrington Chester then to Holyhead will be electrified overhead
Shame they're doing a hodgepodge of discontinuous battery-supported nonsense instead of just doing it all properly the first time.

The class 398s are battery powered not just electric the longer they take the better as I'm catious as there are no toilets on them

Going back to the days of the old 116 units that had no toilets
@@andrewbutler6477 yeah sucks I believe some of the DMUs had toilets on some didn't
