Haymarket to Dalmeny electrification

[najaB]

I haven’t seen any additional steelwork appearing on the bridge either, which is a little disappointing.

Or maybe it's just that good at blending in!

 

[Falcon1200]

Considering that much of the Forth Bridge is a mass of steelwork I'm not sure a few masts, and wires hardly even visible from a distance, are going to have much of an impact! Slightly different on the viaduct sections but those are not in themselves of any special architectural or engineering merit. Not sure about the salt issue either, the overheads at Saltcoats and Craigendoran seem to cope OK, except when high tide and strong winds coincide when the wires are drenched in seawater, but that shouldn't be a problem on the Forth Bridge.

 

[GRALISTAIR]

Sometimes (certain situations) corrosion is less severe when something is drenched rather than splashed or in salt laden air. There is a special area of study called splash zone corrosion.

 

[Scotrail84]

Theres a couple of masts up at Saughton and maybe a dozen more just north of Edinburgh Gateway station but thats it, seems a bit haphazard really. The bridge work on the route is over a year away as well.

I see from the dec2024 timetable thread that Dalmeny to haymarket will be closing early every evening for the electrification works with the late trains using the Winchburgh chord and reversing.

Only the Edinburgh bound services, the last Northbound fifes still running booked route. This is all crew dependant as well. Not all drivers and guards sign the Winchburgh-Dalmeny cord. Perth/Dundee depots definitely don't.

Pedantically, it's all services between 23:30 and 06:30, which just happens to only affect southbound services in the new timetable.

Inevitably there will be the odd day where the block doesn't take place, and some services run the normal route.

A significant chunk of the Edinburgh depot doesn’t sign Winchburgh/Dalmeny anymore either.

Dare I suggest that portals complement viaduct structures?

The problem with wiring the FB is that if any work needs to neb done on it such as scaffolding erected etc would that not mean that they workers wouldn't get the minimum 9ft safe distance so an isolation would have to be taken to do any work within the 9ft distance?

They've not got long to get drivers and guards refreshed then. Years ago there used to be booked jobs where all you did was went up to Dalmeny, then across the cord. Changed ends at Carmuirs West jn then went back the same way.

The route learning trip over the Dalmeny - Winchburgh chord (5N91) is still in the WTT and indeed runs occasionally. However, it now reverses in the loop at Linlithgow and instead of reversing again at Dalmeny it continues around the Fife circle, outward via Kirkcaldy / back via Dunfermline. It even ran a few times during the reduced timetable!

Most of Edinburgh crews don't sign it now, same with Qst crews. Perth and Dundee crews don't sign it at all now either.

Which can be fixed by... route learning trips.

Maybe for Edinburgh crews but that defo wont happen for other depots.

Winter is coming.

(The following shows a big wave surging through the Forth Bridge. Not my photo).

Winter is coming.

I feel that if we ever get waves quite that big in the Forth then we'll have bigger problems than just some overhead wires.

Indeed, I don't think most of the residents of Leith, Granton, Dalmeny, Queensferry, Dalgety Bay or the Fife Coast will be particularly happy...

I'm also not entirely sure how a victorian painting would influence Network Rail - otherwise the people of Bath should be scared when travelling through Box Tunnel...

It's AI generated, so not Victorian. But possibly steampunk?

Is it AI generated? I ask because it has an artist's signature, didn't expect that an AI would 'think' to do that.

This is one of my photos that has been stolen and used with an image of the Forth Bridge (probably also stolen) by a guy from FreakingNews. In FreakingNews he is called "johnx1" and he has posted there:

"My email and phone are going mental with orders for prints from all over the world and I just got a request to use the image from a science fiction mag who want it on the cover of their next issue."

Here is my photo:

I have written to him, but he has not replied, so if you know him, he's from Rosyth, Kingdom of Fife, Scotland, and describes himself as a "joiner carpenter, artist and writer", let me know please. If you see this image turn up on a magazine or you have anything to do with FreakingNews and can help, I'd be grateful.

Please feel free to fave or comment on this image, the more of you that do will mean the more people will get to see it and I have a better chance of nailing this thieving SOB.

Well given that the clearance below the bridge is about 40m above the highest tides, and anything above a 20m tall wave hitting the shore would probably make the news and destroy a good number of the buildings in South Queensferry, it is probably safe to assume so.

I've been over it in the worst of the weather in an easterly, and you do get salt spray hitting the windows, but definitely nothing of that magnitude.

I seem to remember from my time at work that anywhere within about a mile of the coast is regarded as a Marine Environment as far as salt corrosion is concerned. It’s not the salt water but the salt in the air that affects materials such as copper heat exchanger fins which had to be coated in a special material to prevent their total disappearance within a year. It also defined the grade of stainless steel outdoors.

I'd say further inland than that. I get grew up on an island about 14 miles across at its widest and even in the middle it was a constant battle against rust.

 

[gingertom]

if the OLE at Saltcoats, at sea level, can survive the waves and spray, I don't think we have anything to worry about with the bridge. Nothing that regular inspections wouldn't pick up.

I notice that the line is closed today between Inverkeithing and haymarket for engineering works, presumably for track maintenance rather than electrification works

There was fresh rails ready to go in just north of the airport. It could be that.

Having said that, why do one job when you can do two? I'm sure if there's any electrification preparatory work that's ready to be done now they'll take advantage of the block.

Theres nightly closures from the December timetable change for the preparatory work being done.

Down line is getting renewed immediately south of the A90 road bridge.

 

[waverley47]

Just gone past and there are droppers from the end of the wire runs at least halfway to South Gyle, and the register arms around the curve.

I don't know how far the masts go, but progress is definitely happening.
