Most of the ones I watched talked about the need to get costs down, but yes I think the freight person was the only one to mention a specific number to aim for

Electrification threads July 2023 - December 2023

Electrical Clearance differences between 1500V DC overhead and 3000V DC

DIfference in electrical clearances required for 3kV DC versus 1.5kV DC Overhead systems ?

Is the difference in the railway electrical clearances required for 3kV DC versus 1.5kV DC Overhead systems significant enough to rule it out in early 1900s when Britain planned for a move from coal based steam locomotives to mainly coal based electricity driving 1.5kv overhead electric...

DC Overhead overlap of two substations

Name for section of DC overhead electrification where power from two substations overlaps

I am looking for the English name for this. Here is a diagram of what I'm talking about in case it isn't clear: It's a Japanese diagram, so it uses the seemingly Japan-exclusive term "air section".

Slightly off topic, but Chinese have apparently designed machines to reduce the labour intensive fitting the overhead to reduce costs.

But until recently, robots were not capable of building the overhead electrified structures for high-speed railway lines. The job was thought too complex for machines, according to Wang and his colleagues.
The structures of guy-wires, poles and arms that help deliver electrical power to trains is known as the overhead contact system (OCS).
Building an OCS network for high-speed railways involves sophisticated processes – the pre-assembly of contact network arms and suspension cables, the transport of materials to the job site, and the installation of support pillars and suspension cables.
Installing pillars and suspension cables are particularly dangerous tasks, requiring working at heights under high-stress conditions.
Installing the arm of the contact network on the support pole, for example, requires that a worker first attach a pulley to the top of the pole, then use a rope to tie the arm to the ground and pull it up to the top of the pole, according to Jiang Zhehua, an engineer on Wang’s team.
The procedure requires several workers on the ground coordinating with workers on the pole. If something goes wrong, the job could be fatal, Jiang said in a separate paper published in the same journal.
Because of the dangers and the nature of the work, assembling an OCS network has become the most labour-intensive part of high-speed railway projects, according to Wang’s team.
To tackle the problem, railway engineers have devised automated construction technology, which uses digital data management platforms and intelligent systems for storage, pre-assembly, transport and construction, according to Wang’s paper.
Automated sensors collect real-time data from a construction site, which is then sent to a smart warehouse where automated storage and retrieval systems locate and send the required materials to a smart factory for assembly into the pillars, arms, hangers and other components.
The finished components are then transported by autonomous vehicles to the construction site
Robotic arms equipped with sensors and cameras detect and adjust the position of the components, and then lift and place them into their correct locations.
But even robots face challenges when it comes to building the OCS, according to the engineers.
One of the more complex aspects of the work requires that a large number of wires, poles, arms and other components are installed in a precise and coordinated manner.
The installation site may also provide unique challenges – uneven terrain, natural obstacles, adverse weather or other factors can hinder the installation process. Robots may have difficulty navigating such obstacles or adjusting to changes in the environment.
The OCS installation process also requires a variety of coordinated robotic systems to work together seamlessly to complete the installations.
The solution to these challenges is artificial intelligence.

Another great session hosted by the PWI


A very useful presentation by Chris Pollock of Botham Network Solution with an excellent Q&A session.

Delivered for Freight: Developments in the rail freight industry over the past 5 years - Chris Polack​


In essence the message is the same as Andrew Lloyd Webber’s lyric “Freight Is Great, Freight is Great – It takes the loads from off the roads – so Freight is great” .

Fantastic to see. Had a quick skim of that thread and it's a shame that links to the WCML & MML (the latter via the Dudding Hill Line) aren't included, but it's great that that route's finally getting wires at all!
Hopefully that could be incentive to wire up more Western freight routes in the future...

Interesting that neither Huddersfield to Westtown nor Westtown to Leeds is included. Presumably that means that no part of either is expected to go live before CP8?

Also no MML north of Wigston, and nothing in Scotland after EK, presumably because nothing is fully committed yet.
