Step-Free Access Between Train And Platform On The Elizabeth Line

Any new railway with new trains, should have step-free access train and platform.

I know that this has not always happened in the last few years, but how does the Elizabeth Line match up.

I’ve taken these pictures in the last couple of days.

On  this evidence, it certainly seems that the access between train and platform is step-free, between at least Woolwich and Paddington stations.

Offshore Wind Champion Appointed As £160m Floating Offshore Wind Fund Opens For Expressions Of Interest

The title of this post, is the same as that of this press release from Kwasi Kwarteng.

These three paragraphs describe the policy.

Ambitious plans to expand offshore wind around the United Kingdom to power homes and businesses with cheap, homegrown energy received a further boost today with the appointment of a new government champion and a multimillion-pound manufacturing fund opening for expressions of interest.

The appointment of Tim Pick as the first UK Offshore Wind Champion was confirmed by Prime Minister Boris Johnson and Business and Energy Secretary Kwasi Kwarteng today.

The Floating Offshore Wind Manufacturing Investment Scheme (FLOWMIS) will provide £160 million in government funding to boost floating offshore wind capability around the UK at sites in Scotland, Wales and elsewhere by supporting manufacturers and giving private investors the confidence to back this emerging sector which is expected to rapidly expand in the years ahead.

Floating offshore wind needs the following components.

  • Wind turbines, which are the same as those used onshore.
  • Floats, which are generally made from steel, but concrete can also be used. There are a few proven designs, like the Windfloat from Principle Power.
  • Mooring systems for the turbines.
  • Electrical substations and cables.

There is also a need for deep water docks, with large cranes to assemble the systems, prior to towing the turbines into position.

Floating offshore wind is a new industry and there will be new ideas coming through from innovators.

I feel that the strategy could help bring new ideas through.

The Story Behind The Concrete Panels On The Elizabeth Line.

These are a selection of the pictures I took yesterday inside Elizabeth Line stations.

Note.

  1. The walls and ceilings appear to be covered in light grey panels with holes.
  2. The material appears to look like concrete.
  3. Every one is a totally different shape, so how were they manufactured?

This article on Ian Visits is entitled How Crossrail Is Using 3D-Printing To Build Its Stations.

This is the two opening paragraphs.

When you start to use the new Elizabeth line stations, among its many achievements will be the first large scale use of 3D-printing in concrete.

The use of 3D printing has made possible one of the more distinctive features of the future Elizabeth line stations — the curved concrete panels that will line the inside of the passenger tunnels and some stations, and sinuously glide around corners in a way never seen before in a tube station.

There will be a total of something like 36,000 of these panels and although printing each in concrete is possible, Crossrail would probably have been delivered in the 2040s or 2050s.

The contractors used an innovative process called FreeFAB, which had been invented by an Australian architect.

  • The process creates a wax mould for each panel using 3D printing.
  • This mould is then used to create the actual panel.
  • After each panel is cast, the wax is melted off and recycled.
  • The panels are made in a factory in Doncaster.

We will see a lot more of this technique used in the construction industry.

Elizabeth Line – Abbey Wood Station – 24th May 2022

I took these pictures at Abbey Wood station on the Elizabeth Line.

Note.

  1. Abbey Wood station has four platforms, three bridges and six lifts.
  2. In Abbey Wood Station Opens, there are pictures from when the station opened in October 2017.
  3. The interchange between the North Kent and Elizabeth Lines seemed to be working well.

It will be interesting to see how this station changes to accommodate more Elizabeth Line services to Kent.

Elizabeth Line – Custom House Station – 24th May 2022

I took these pictures at Custom House station on the Elizabeth Line.

Note.

  1. The station was built in a factory and the concrete beams were assembled on-site. Traditionally, the concrete structure would have been poured on site.
  2. The quality of the columns is excellent and an engineer I spoke to a few years ago, said that the methods used at Custom House station ensure a high quality building. Look at the last two pictures.
  3. The two escalators are in-line, rather than side-by-side and it looks like this was done to squeeze in the station.
  4. There were signs up for toilets, that are visible in picture 4. Are they going to be installed?

The ideas used to create Custom House station, will be borrowed by architects and builders all over the world.
