Portskewett Pylons

[mjlangford]

Hello People

Its been a while since i was last logged in, hope you are all well. I've posted some photo's of what I think are interesting pylons near Portskewett. I hope the link below works.. if not please tell me

It's a real shame as I these shoots where a bit rushed. Having spent some time composing some nice shoots only to then have my SD card fail. So after rushing back to my mates house to get another card, time was a bit against me

Lesson leaned.. Always carry a spare card

I had took some pics of a very unusual terminator in Ledbury, guess I will have to go there again to take that one.

Also any comments on these photo's are welcome. Not been using a DSLR very long, so any comments on the quality of my pics, or suggestions on how to improve them are welcome.

Bye for now

Good to see you again!

Great photos, and interesting extension! Thanks for posting these.

Other people, do have a look at this set.

Excellent pictures. In one of your pictures the tower number "4YX 149A" is a rather large long name. Most of the towers I have seen in the Northwest and Midlands (National Grid and DNO) have much shorter numbers eg VA25 or VK12 etc. Perhaps people from other bits of the UK could quote some typical Tower/Circuit numbers?

Nice set of photos. I think these towers were mentioned in a recent thread and I believe these three towers shown were originally intended for a substation that was to be build at Portskewett once the 400kV had come under the Severn.

The additions to the top arms suggests this is a variation on the standard L6 DT90 tower as the tower at Stalybridge lacks the top arm extentions but otherwise the same design of tower.

Re the route codes from what I have noted over the years most L2 and some L3 routes use codes starting with V to Z e.g.

Macclesfied to Bredbury (my local) L2 is YV
Stalybridge to Bredbury L2 is ZZC
Bredbury to South Manchester L2 is YO
South Manchester to Daines and Carrington L6 is ZZNDrakelow to Cellarhead to Daines L2 is ZE

Stalybridge to Thorpe Marsh L6 is 4ZO
Trawsfyndd to Pentir is 4ZC

So the 400kV L6 routes that came after the original 275kV L2 supergrid and uprated lines to 400kV are usually coded 4xx whereas the 275/400 L2 and L3 lines are coded Vx to Zxx. I guess they ran out of codes between VA and ZZ so went onto ZZB to ZZZ??

Branches from main routes are coded as per the example ZEA is the branch from the main ZE route. However I am not sure if the same would apply to a 4xx coded route - this might be something like 4ZZA line. I haven't seen any coded like that but then again I haven't seen all the lines lol.

Towers are also subcoded with the individual tower number but as shown in the photo then can be suffixed with A, B, C etc. where additional towers have been inserted in the line between say tower 4YX 149 and 4YX 150.

However if a tower is coded say YV 47R then this means that the original tower has been replaced by a new one in the same position perhaps due to damage, age, or in the case of YV 47R this was reduced in height and moved back by about 50-60 ft to its new position as it was in the way of the proposed A6M bypass in 1991, which as you may have guessed never got built . Another example would be ZZC 41R, this was originally an L2 D tower when the line was built but was later replaced in the same position by an L2 DJ90 tower to allow the YV line to connect.

This is information that I have collected over the years, I'm not saying its correct but it seems right.

Would it be worth making a list of known route codes or is that taking things a little too far??

I sort of know the route codes to the local L2 routes to me.

Hinkley Point to Melksham (my local) L2 is ZG
Melksham to Minety L2 is ZF
Minety to Feckenham L2 must be ZE
Melksham to Basingstoke L2 is YYM

The local PL4 line to me is CC

No sure if you can have two routes with the same code ZE???

Some more local to me are

Stalybridge to junction with ZP route near Littleborough is L8/L2 ZPA
Rochdale to Eggborough I think is ZP throughout but not sure at Eggborough end as lines have been changed.
The westward continuation of the same route on which the famous Pink Pylon was located was also L2 ZP as far as the junction with the ZQ route.
Rochdale to Whitegate is L2 VJ
Whitegate to Kearsley is L2 VK
Penwortham to Hutton at least is L2 ZX - not sure of section over Shap towards Harker
Carrington to Daines to Deeside (Connah's Quay) is L2 ZO
Melksham to Imperial Park and Cilfynydd is L6 4YZ - so what would that make the recent L12 branch to Seabank power station then???
The original L3 route from Melksham to Iron Action over the Severn to Whitson perhaps beyond is XL
Bramley to Didcot is L6 4YG

Probably got some more somewhere ;D

I was wrong,

Minety to Feckenham L2 is ZF still and the L3 line next to it is MCR.

Melksham to Minety and Minety to Feckenham must be the same route.

If I remember the Pink Pylon was ZP 226.
