Harringay Station – 20th November 2022

This article on Rail Advent, is entitled Essential Improvements Programme For Harringay Station Gets Underway!

These two paragraphs outline the work to be done.

Harringay station will see major improvement work carried out including vital work to reinforce the footbridge which is located inside the station, making it fit for purpose into the future. The bridge is also the home of the old ticket office which will also be relocated in order to comply with building regulations.

Both platforms will see brand new waiting shelters and will allow passengers heading to destinations like Welwyn Garden City, Stevenage and Moorgate are able to keep dry in a sheltered location whilst waiting for their train leading to improved passenger experience.

It appears the work will not inconvenience passengers.

So earlier today, I went to have a look at Harringay station.


  1. All trains calling at the station are Class 717 trains.
  2. The old ticket office is on the bridge.
  3. The platforms are rather narrow.
  4. The train-platform access is not good.

The bridge has certainly seen better days, but then it does date from 1885.

I have some thoughts.

Digital Signalling

Digital signalling is being installed on the Great Northern route and the Hertford Loop Line and this could mean up to ten trains per hour (tph) into Moorgate.

The Current Service

At present there seems to be only two tph on these two routes.

  • Moorgate and Stevenage via Hertford North
  • Moorgate and Welwyn Garden City

This is an insult and both routes need at least four tph all day to attract passengers.

The Ultimate Service

It can certainly have a frequency of around eight tph between Moorgate and Alexandra Palace stations.

But no predictions have been made about what frequency will be used once the signalling is complete.

What A Depressing Opening Game For A World Cup!

I’m sure that the game would be more exciting if Hartlepool and Forfar had been asked to put on an exhibition match.

I think the score was three-nil to Ecuador, as like the BBC panel, I can’t see any fault with the goal that was disallowed by VAR. But then like the BBC panel, I haven’t accepted any brown envelopes!

German Startup EVIA AERO Commits To Hydrogen-Powered Britten-Norman Islanders

The title of this post, is the same as that of this article on Simple Flying.

These two paragraphs outline the deal.

EVIA AERO has signed a letter of intent with Cranfield Aerospace Solutions (CAeS) to increase its order for hydrogen modification kits and aircraft. As part of the agreement, the startup airline expects to receive five additional hydrogen modification kits and ten 19-seat aircraft.

The hydrogen modification kits are designed to power the nine-seat Britten-Norman Islander aircraft and come in addition to a previous order with CAeS for 10 kits.

I can remember seeing the Islander prototype at a Farnborough Air Show in the mid-1960s on the BBC with commentary from the iconic Raymond Baxter.

University Of Manchester And National Grid Team Up To Develop SF6-Free Retrofill Solution For Electricity Network

The title of this post, is the same as that of this press release from National Grid.

This is the introductory paragraph.

National Grid and the University of Manchester are to collaborate on a four-year project to develop a full-scale demonstrator at the Deeside Centre for Innovation, designed to test at scale how the UK can retrofill sulphur hexafluoride (SF6) across its network of high-voltage equipment.


  1. Sulphur hexafluoride (SF6) is a gas commonly used in the power industry to provide electrical insulation and arc interruption.
  2. Eighty percent of sulphur hexafluoride is used in the electricity industry.
  3. According to Wikipedia, sulphur hexafluoride has several important applications, including a medical one in eye surgery.
  4. But sulphur hexafluoride is a is a potent greenhouse gas with a global warming potential that is 25,200 times greater than CO2.

It certainly looks to be a good idea to see if the sulphur hexafluoride can be eliminated from electrical equipment and other uses, that may release the gas into the atmosphere.

These paragraphs from the press release outline the project.

The £1.9m project will see experts at Manchester help determine how National Grid can develop a retrofill solution to replace SF6 with an environmentally friendlier alternative without having to replace or otherwise modify the existing equipment.

This solution – to be demonstrated at National Grid’s test facility the Deeside Centre for Innovation – will mean National Grid can avoid the environmental impact and cost of replacing equipment otherwise fit for many more years’ service.

It is not the first time National Grid and the University of Manchester have teamed up on a project exploring SF6 alternatives – a previous initiative which concluded in 2020 is now up for an IET Engineering & Technology magazine innovation award for ‘Best Innovation in Net Zero and Sustainability’.

The press release also says this about the Deeside Centre for Innovation.

National Grid’s Deeside Centre for Innovation in North Wales is the first of its kind in Europe, where electricity network assets can be tested under real life conditions, 24 hours a day, seven days a week.

It certainly seems that National Grid and Manchester University are on top of the problem and have the resources to achieve success in the project.

The Russian Attack On Ukraine

You may wonder what this has got to do with improving transformers and switchgear in Manchester and Wales.

Recently, the Russians have been targeting the Ukrainian electricity network. Are Ukrainian transformers and switchgear insulated with sulphur hexafluoride and if they are how of this potent global warming gas has been released into the atmosphere?

ZERRCI – Zero Emissions Repowering Of Railway Construction Infrastructure

This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.

In this document, this is said about the project.

Project No: 10037562

Project title: ZERRCI – Zero Emissions Repowering Of Railway Construction Infrastructure
Lead organisation: EMINOX LIMITED
Project grant: £59,852

Public description: Eminox, HS2 and SCS Railways propose a solution for the delivery of a low emissions, greener
railway. Our solution covers the development of an electric motor and battery system, which can be
retrofitted into existing construction equipment, replacing the traditional diesel engine with a quieter,
cleaner, zero emissions drivetrain. These pieces of plant and equipment will be used as direct
replacements for diesel machines in the constructing and maintaining railway infrastructure.

Eminox is leading this project with its experience in providing cost effective retrofit emissions
solutions and together with HS2 and SCS JV will be involved in demonstrating the first repowered
construction equipment in a real-world rail infrastructure environment.

This proposed venture has been instigated by HS2 in line with their ambition as set out in their Net
Zero Carbon plan for diesel free construction sites by 2029. As the solution will extend the life
expectancy of the machine, it will contribute to HS2’s vision of net-zero by 2035.

This solution will offer a more cost-effective route to zero emissions construction compared to
purchasing similar new electric powered equipment by extending the life expectancy of existing
plant and machinery. With a target of 50% the price of purchasing new excavators it is expected to
incentivise the broader uptake of demand in electric plant and equipment at scale across the
industry supply chain.

Phase 1 of this project aims to deliver a proposal for a prototype zero-emissions excavator. By
performing a feasibility study on the conversion principals, we intend to extract a broad
understanding of the challenges associated with integration and develop an optimised battery and
motor system specification.

Phase 2 will involve the conversion, commissioning and delivery of a repowered excavator, and
subsequent in-service validation. By using this converted machine to conduct initial trials, it will be
proven that no machine functionality or safety features have been compromised during conversion,
and we will establish power storage requirements to provide adequate duty cycle performance.

This will result in a fully proven demonstrator with real-world validation enabling further
development of optimised battery solutions.
