Yes, quite. I probably should not have started speculating - I do dislike it so! Let's not... My apologies to all.

extensionsPerhaps time to close this epic thread and start new ones when/if extensions/deferred bits etc are started?
sorry what does 'extensions/deferred bits' refer to. Are there bits outstanding to do in the tunnels.Including Patchway???)Perhaps time to close this epic thread and start new ones when/if extensions/deferred bits etc are started?
An extension would be for example Cardiff to Swansea.extensions

It didn't seem that way over breakfastHow do you mean? A temporary repair was made, trains are now running normally on electric through the tunnel.
It’s all done now, I’m not sure there’s anything exciting to add now until (and if) there’s any progress on the indefinitely deferred parts of the scheme.

Good news but so sad that with all major schemes just about complete all those hard won skills and expensive plant will now be most likely lost before the politicians act.It's now being reported that it's compleated:
Network Rail completes Great Western electrification
Network Rail (NR) has successfully electrified the Severn Tunnel, completing the truncated Great Western electrification programmewww.railjournal.com
Ken obviously didn't get the memo that he would be getting his cheque book out this time...Here we go again.
"Secretary of State for Wales Simon Hart said he hoped to continue to work with Network Rail to grow Wales' economy and create "world-class transport infrastructure" in Wales.
“It is crucial that Wales has cutting-edge transport links to help people travel to work, encourage inward investment and better connect it to the rest of the UK in order to boost prosperity," he said.
Ken Skates, Minister for Economy, Transport and North Wales, said: “The completion of the electrification works in the Severn Tunnel is welcome news in terms of improving journey times between capitals and delivering towards our decarbonisation agenda for transport.
“I hope that the completion of this work can be taken as a strong signal of intent from Network Rail and the UK Government that there is more investment to come to improve journey times and capacity across South Wales in the future, including electrification westwards beyond Cardiff."

No quicker than today as there is a speed limit from STJ through tunnel and up to Patchway and still stops at Newport.What will the quickest Cardiff journey time be (non stop to Bristol Parkway)?
What will the quickest Cardiff journey time be (non stop to Bristol Parkway)?
1h43 on the 1715.
To do 146 miles according to Railmiles. Bristol Parkway is 112 miles - is that doable in 1h10 with only a stop in Reading?

On Series 1 equipment, the single track I-section columns (which do look like ECML-style headspan masts to the untrained eye!) are nominally very tall so as to give the catenary & contact a wide berth from the Auto Transformer Feeder wires. Where the video shows the train crossing the M4 (15 minutes in) is an example of that, but slightly before, there were some masts that height with no ATF equipment on. I can only suspect that the original design for aerial ATF was superseded by a requirement to bury it in a cable trough - which, at a closer look, is due to National Grid pylons sailing overhead a little too close for Network Rail's comfort.From past discussions it's a wide variety of factors including but not limited to
Watching the video you refer to (
- Neutral sections
- Catenary tensioners
- Ground conditions
- Possession availability at time of installation
- Torsion wind loading
- Signal sighting
- I have added a timestamp for reference) I don't think it looks that 'random' at all.
Oooh!I can only suspect that the original design for aerial ATF was superseded by a requirement to bury it in a cable trough - which, at a closer look, is due to National Grid pylons sailing overhead a little too close for Netowrk Rail's comfort.
Oooh!
Good spot, think you're right.
If it's a pair of 5-cars they will each have one pan up, unless one unit is dead. 9-car units aren't allowed to have more than one pan raised.saw a few 800s, which appeared to have 2 pans up - really?? or old age??
I thought last December’s timetable was supposed to have accounted for wiring completion, but with some trains still missing from the timetable?Are we now seeing the full benefits of the GWML Electrification with some decreased journey times or do we have a lot more to come? IF we have more to come, what are we waiting to happen before we can see the full benefits of the electrification?
