Class 345 progress | RailUK Forums (railforums.co.uk)


Network Rail is upgrading the overhead electric wires near London Paddington to improve the reliability and performance of our train service.
To allow this work to take place, London Paddington station will be closed on Sunday 7 March, and trains will not run between Ealing Broadway and London Paddington.

Train services across our network will be impacted by this, and customers will not be able to travel directly into London on GWR services.

Is that the fantastically expensive overhead with great chunky gantries that they had to put in and blow the budget because it would be so much better than any wiring they'd done previously?

No, it is the 1990s electrification of Paddington which is presumably somewhat different.

No, it will be the cheap as chips OLE put in east of Airport Jn that needs fixing to be as reliable as that to the West of Airport Jn

They're putting more of it in, so yes, but not in the way you meant.

They’ve been gradually improving the original OHLE between Paddington and Airport Junction, it was mentioned fairly often in the long running GW electrification thread. There are photos somewhere of how they replaced various headspans with gantries, and the inference was always that it would be ongoing for quite a few years yet.

The closure of the Hex depot and lifting of its tracks presumably also has an impact on the junction wiring?

So, probably nothing to worry about here really?

For info this post (#1912) in the GW Wiring thread from 2016 links to a video about the changeover:

And probably a very good time to do it given the minimal number of passengers who will be inconvenienced.

Reception Line 1 is being taken out of use from Friars Jn. towards Paddington, as part of the HS2 works.

using lots and lots of extra gold plating I assume !:)
I believe there's a quote by a bike manufacturer along the lines of 'Performance, Lightness, Cost: pick any 2'. It's not directly relatable, but shares a similar sentiment.

A mantra in most businesses:
High Speed / Low Cost / High Quality
Pick any 2. It is impossible to have all 3.

- You can have it cheap and quickly, but it won't be good
- You can have it cheap and good, but it will take a long time
- You can have it fast and good, but it won't be cheap
etc
