How do you access the bridge numbers? I was planning to have captions saying ‘Colton Lane OB’ for example.Location of piles and any civics interventions such as bridge numbers etc

Both ideally!! Please and thanks
1. That is the Power Supply Building that's been mentioned a few times in the NR monthly tracker.A quick few questions:
1. What is going here? This is just north of Church Fenton next to the Down Leeds.

2. Is a return wire the same as an earth wire?
3. Is ‘arm’ the correct term to describe what is connected to the SPS?
Also not a question as such, but I couldn’t find the numbers for all of the bridges on the website linked.
Ahh I see - well that's the cantilever frame that's been installed on both sides. Last thing they need is the registration arms.
I've often wondered with these structures, would it not be possible for the further away wire (the one currently attached using the enormous cantilever) to be attached using a slightly longer, upside-down version of the support arm found on the closer track, to reduce the amount of steel used? (This might come at the expense of a slightly taller mast.) With a lower mass of steel hanging to the side, there would be a lower bending moment, so potentially the mast and foundations could be made less substantial as well?
whats the advantage of a cantilever. surely Mk3 was simpler. 1 mast each side of the railway. or a portal.I've often wondered with these structures, would it not be possible for the further away wire (the one currently attached using the enormous cantilever) to be attached using a slightly longer, upside-down version of the support arm found on the closer track, to reduce the amount of steel used?

A bit like this:

Also a good question! Personally I think single masts either side of the track is better, but there are a number of possible benefits of twin track cantilevers. Theoretically you could have the adjacent line open to traffic during installation, as all the masts are on one side, but I doubt it happens in practice ("because safety"). You also need half the number of masts and foundations (but they need to be a lot bigger).whats the advantage of a cantilever. surely Mk3 was simpler. 1 mast each side of the railway. or a portal.
....but Church Fenton to Colton Junction is four tracks, so surely you would need the same number of masts and foundations?You also need half the number of masts and foundations (but they need to be a lot bigger).
To my eye, twin track cantilevers are much less elegant than a very simple mast on either side. They jar with the surroundings in a way that simple symmetrical masts don't, primarily because of the extra steelwork required.whats the advantage of a cantilever. surely Mk3 was simpler. 1 mast each side of the railway. or a portal.
You need the same number of masts and foundations as a gantry, but the advantage is you only need to close 2 tracks at a time rather than blocking all 4 as you would need to put the gantry boom across.....but Church Fenton to Colton Junction is four tracks, so surely you would need the same number of masts and foundations?
Half the number of foundation though. Even if the piles need to be a bit longer, that's got to be a fair saving.To my eye, twin track cantilevers are much less elegant than a very simple mast on either side.

Aren’t the piles both longer and bigger diameter thus heavier? If so, it’d take more power to handle and plant them. Isn’t that why the HOOPS wasn’t much use on GWR.Half the number of foundation though. Even if the piles need to be a bit longer, that's got to be a fair saving.
No idea on progress there - I believe @GRALISTAIR has more details.Any progress on the stalybridge line?
Was on the train from York to Leeds this morning and noticed the gantries just stop outside church fenton station.

I wish I did sorry. Now back in the USA and at Xmas-New Year surveyed Lostock Jct to Wigan only.No idea on progress there - I believe @GRALISTAIR has more details.

Ah shame - can't be helped I suppose!I wish I did sorry. Now back in the USA and at Xmas-New Year surveyed Lostock Jct to Wigan only.
E1 = North of Church Fenton to York - good question.Final quick question - What are the names of all of the compounds on E1?
According to that link it is only 5 milesWe’re upgrading the route between York and Church Fenton to provide a more reliable and resilient railway for passengers
so I would not have though there would be too many.The five mile stretch between Church Fenton and Colton Junction
There's mast bases in all the way from Miles Platting to Clayton Bridge crossing, apart from the former Park station and Philips Park West junction.Any progress on the stalybridge line?
Last time I went that way I noticed base's all the way to Ashton Moss Jn, just before the M60 Bridge.There's mast bases in all the way from Miles Platting to Clayton Bridge crossing, apart from the former Park station and Philips Park West junction.
Probably bases further east than that but I was busy doing other things to notice!
