Some photos from yesterday for the record.

I have taken a full revolution of said structure not long after it opened visiting family in that part of the world. We used the touring narrowboat, with half a turn up; through the tunnel and return finishing with a half a turn back down. A wonderful piece of engineering.

So far
1. Stratford (not-upon-Avon) - eightonedee
2. Melksham - ChrisfromNailsea
Indeed, this is the nearest bus stop "for" the station; it's a 6 or 7 minute walk (physically quite close but no direct route) and involves crossing a busy "A" road with no pedestrian crossing.
6. Beaulieu Park - stuving
No lifts / slopes on this bridge - so it must be the secondary way between platforms with another route available. The width of the steps looks astonising - very optimistic? -
8. Paddington - Oxonhutch

Probably thought with an airshow going on they'd have an opportunity to tarmac a runway?
Oddly a temporary tarmac pavement has been laid in front of the new sea defences that will be paused for the summer.
If it was laid by those new residents of Paignton Green, it will be very temporary indeed.
I am a great fan of David Johns' video blog 'Cruising the Cut' on YouTube.

If all trains cancelled for the day, taxis will be provided. They can't leave you stranded
Indeed - if you know to ask ... the industry systems that talk to passengers should as a matter or course (IMHO) suggest practical alternatives to tell people how they can make their journeys and not leave it up to the wannabe-passengers to say "oy!". The systems for this have improved, but remain patchy as illustrated yesterday.
In the end, the final round trip train ran yesterday, and indeed the [Melksham time] 08:02 and 09:09 that were "cancelled" earlier in the week had been re-instated, giving a 11.8% cancellation rate for the last week. There are two more cancellations already flagged up for today, so the stats in this report will get worse unless the cancellation are then reversed.

.....Passengers travelling to Europe from the Port of Dover earlier faced delays of several hours, due to the introduction of a new entry and exit system.....
Rather amusingly, at around 09:30 on Saturday due to the queues becoming unmanageable the French Border Police stopped using the EES and reverted to the good old stamping of passports. This has been confirmed by Simon Calder.
So it is not just our government that are crap at designing & implementing technology!
From https://www.scottishcanals.co.uk/visit/canals/visit-the-forth-clyde-canal/attractions/the-falkirk-wheel
The world’s only rotating boat lift, The Falkirk Wheel links the Forth & Clyde Canal to the Union Canal 35 metres above, allowing vessels to sail through the sky thanks to a unique fusion of art and engineering – and the same power it would take to boil eight kettles.
Transforming the contaminated site of a former tar works, The Falkirk Wheel opened in 2002 and replaced a flight of 11 locks that once stepped the Union Canal down to the level of the Forth & Clyde, more than 100 feet below. Whereas weary travellers once had a day’s heavy work opening and closing 44 lock gates to complete the journey between the two canals, The Falkirk Wheel allows vessels to transit between the two waterways in just a few minutes.

An update, from the BBC:
Hottest day of year as 30.5C recorded and temperatures set to soar
Temperatures will continue to soar across the bank holiday weekend following the hottest day of the year so far on Saturday.
A high of 30.5C was recorded at Frittenden in Kent, beating Friday's maximum temperature of 28.4C at Heathrow in London, Cranwell in Lincolnshire and Cambridge.
The Met Office said it was very rare for the UK to record temperatures above 30C in May, with the last time being on 25 May 2012.
The heat is forecast to intensify throughout the long weekend, reaching heatwave criteria in a number of locations. Daytime highs are forecast to reach the upper 20s Celsius in many areas, with the low 30s Celsius likely in the week ahead.
Amber heat health alerts remain in effect for the Midlands, eastern and south-east England.
Amber alerts mean there is a risk of a significant impact across health and social care services, with children and those aged over 65 at risk of negative health implications.
The remainder of England is under yellow heat health alerts, meaning adverse weather is "likely to affect vulnerable groups".

Cancellations to services between London Paddington and Reading
Due to a fault with the signalling system between London Paddington and Reading fewer trains are able to run on some lines.
Train services running to and from these stations will be cancelled or delayed. Disruption is expected until the end of the day.

2. The woefully restricted access on the bus stop on Shurngold, Melksham - just north of the railway station, as the crow flies, but a significant hike if you are on foot. No wheelchair access.

Network Rail also have a page of information about this work:
I think they are not "replacing 838 bridge arms", but installing them in place of what was put there in 2019. Unless there has been more going on in the interim, and I missed it, that is Furrer+Frey's ROCS beam system but with aluminium contact wire clamped underneath it rather than the usual copper. That was meant to reduce the corrosion to manageable levels, with increased maintenance. But it looks as if they think having a third go at it will improve that further.
Innovative Severn Tunnel upgrade to transform key rail link between South Wales and England
Region & Route: Wales & Western: Wales & Borders
Passengers are advised to plan ahead as Network Rail carry out major upgrade in the Severn Tunnel and Bristol area, with replacement buses and diversionary routes in place to keep people moving from late May to early June.
This vital project will see Network Rail, and contractors ARQ, complete the transformation of the Severn Tunnel’s overhead power system, designed specifically to withstand the tunnel’s harsh, corrosive environment - making it more resilient, reducing the frequency of maintenance, and helping to minimise disruption for passengers.
The work will take place around the clock from Saturday 23 May until the early hours of Tuesday 9 June, with the railway closed between Newport and Bristol Parkway during this time.
The new system
Running beneath the Severn Estuary, the 4.35-mile Severn Tunnel is one of the toughest environments on the UK rail network, where moisture and saltwater accelerate wear on equipment.
Since electrification, the overhead power system has been prone to corrosion and electrical wear, leading to more frequent maintenance.
To address this, Network Rail’s Wales and Borders team has developed and successfully trialled an innovative new system. It uses a single 7km copper contact wire supported at regular intervals by modified bridge arms, to eliminate previous corrosion issues and improve performance.
Engineers will now install this system along the full length of the tunnel - using a world-first approach on this scale - to create a more resilient railway and reduce the need for frequent maintenance.
The programme of work involves:
Replacing 838 bridge arms that support the overhead electric wires in the Severn Tunnel
Renewing 9,000 metres of overhead wiring in the Severn Tunnel
Carrying out track and infrastructure upgrades, and drainage works in the Bristol and Patchway areas.
Alongside the tunnel work, Network Rail will also carry out improvements in the Bristol area, including upgrades to the railway serving the new Bristol Brabazon station on the former Filton airfield site. The station is due to open in the autumn and will bring passenger services back to the Henbury line for the first time since 1964.

The contact wire is copper (standard OLE profile) it is clamped in an extruded aluminium beam; the beam is supported by "bridge arms".
It has always been know that Seven Tunnel is a hostile environment ie high humidity. I know the Route electrification engineers have been looking for an improved conductor beam and support system

It's coming up to 9 years since Grayling killed parts of Great Western electrification (it was July 2017)
As photographed above there are a number of masts west of Chippenham doing nothing. I think about third of the mast bases and a few masts were also installed Didcot - Oxford.
Things have moved on with cost control, and the stupidity of not resuming it once costs were controlled has never really made sense as a long term strategy (and even less so in new era of high diesel prices).
Ironically the delay to ordering replacements for 158,159,165,166,168 diesel fleet might benefit a few electrified sections, if it means battery charging is possible, and don't have to fit diesel engines (which require servicing and maintenance of the engines). There is obviously a cost implication of adding diesel generators to replacement fleet (plus ongoing extra operational costs), which could be used to pay for some of the electrification instead.
But doing joined up thinking, or any form of mid or longer term planning seems to be beyond current batch of ministers, who seem to be more into short term thinking and regular U turns

Why was it stopped? Was it way behind schedule and/or over budget?
Was going seriously over budget, (and behind schedule) and instead of saying pause and refocus, just took axe to it. Ignored the ongoing alternative costs it created.
It was a time when skills were being outsourced to consultants, so something like a drain cover where a mast was planned, meant leaving it, getting consultants out again, redesigning, expensively coming back later with electrification train. Rather than having skilled and empowered staff doing simple tweak to plan there and then.
The structure at the time was not incentivised to get it finished as efficiently as possible, but was more like see what extra work and revenue can get from it. HS2 contracts were devised in same cost plus era too.
Agreed the GW electrification went over budget, however the DfT got the electrification the specified but then complained it was too expensive and taking too long. Also they dithered over the Oxford station rebuild and failed to take on the NIMBY in Bath and Chippenham area may be there were a few MP's worried about their seats
Incidentally, 'on this day', 23 May 1832, the Ffestiniog & Welsh Highland Railway was established.
Indeed - added to "on this day"
From https://www.festrail.co.uk/ffestiniog-railway-history/
In 1830, shortly after Madock’s death, Samuel Holland, who was quarrying slate at Rhiw, joined Henry Archer, a young businessman from Dublin, to promote the Festiniog Railway, incorporated by Act of Parliament on 23 May 1832. James Spooner from Worcestershire was responsible for the survey and construction of the Railway.

For some ten years, before I retired, I was a grocery delivery driver with Waitrose.
John Lewis (of which Waitrose is the grocery part) is a mutual partnership, where the partners are all members and there are no shareholders.
The partnership stance was that gratuities should be declined, politely, while the alternative of giving any customer feedback online was to be offered.
There was one memorable exception to that, in my experience, when a very strong-willed customer in Chew Magna (a village south of Bristol) almost bullied my line manager at the time into giving me a pack of beer in appreciation of my customer service.
That particular customer, by the way, was a very interesting individual: he was Greek, but he retired as 'Head of English' at a posh school, and is a keen Arsenal fan.
