My shredder was running more slowly than usual. I see its motor sparks quite a lot, and presume this is because the motor’s brushes are worn out. But where to obtain brushes measuring 5.4 x 3.9 mm (prob about 10mm long when new)?

An unusual situation which amused me – to have closed all three of my Apple Watch activity rings by 1 minute past noon! (By exceeding 500 kCal of activity, 30 mins of exercise, and to have stood up & moved around during each of 12 hours.) How did I do it? Night-shift then parkrun! 🤭😂
Screenshot from my Apple Watch at one minute past noon, showing that I had already closed all three Activity Rings.

Very sorry to hear that Alessando "Alex" Zanardi, former F1 driver and Paralympian, has died. Here he is, captured by my analogue camera as he signed autographs just outside the F1 paddock at Silverstone after Qualifying, on 10 July 1999; he was a Williams F1 team driver that year.

Ahh, haven't been to Marseilles-St-Charles since 1994. But here's (a very small scan of) my photo of an original TGV there, which I must have taken in 1992.

Good plan. I hope some enforcement is carried out too. The alley beside Aldgate station (close to where I saw this during 10-minute turnaround + stepping-back this morning) resembles an open sewer.

Two go-arounds for this Eurowings A319 from Hamburg just now, I heard it and wondered why it was painting a line that it was already following!

Or you could be blowing them all off a pavement into a cycle-lane, completely obscuring and blocking it...

In October 2018 the People's Vote march attracted *several times* the number of protesters to the thugs' march which happened yesterday. Particularly noticeable the total, utter absence of violence or any vestige of unsafety. The only police we saw all day were these 4 seeking to reopen Park Lane.

While my train was at Chesham this morning, I took a little walk along the public footpath that runs beside (and then crosses over) the branch line. I walked far enough to see signal A1000, which usually displays Yellow to trains — but as my train was occupying the single line there, it shows Red.

Mmm, Glenfield Tunnel! I drove all the way to Leicester in 2017 on purpose to visit it. :) I love the facility of having old maps at our disposal.

I see the RAIB is investigating a recent derailment at Denbigh Hall South Junction, between Bletchley and Milton Keynes. It occurred at a Switch Diamond Crossing. The selfsame set of points may be seen in the attached framegrab from my cab video footage (from April’s HDL East West DEMU).

This is signal TVC 682 at Latchmere Junction. Route "G" is shown on the indicator, which seems to be a route which takes you to Longhedge via the 'wrong road'. Is there a list of routes and indications for this and similar signals?

I don't believe it can be. I think it'll be very close to where the photographer in your post was situated, where no.12 facing crossover is, beyond which further points lead into SMD Departure & Holding Roads. The junction even has a Trackernet code, I see, SDJ.
ROUTEING OF TRAINS
Signal Operators may vary the routeing and platform working of trains in the best interests of the service.
Eastbound trains shown within this timetable as running 'via WB Line' will do so between Stratford Market Junction and Stratford.

View of track by Egham substation. Bus-bars connecting the traction current return path to the substation (just out of shot to top). Ordinarily these would be impedance bonds, but here they just seem to be direct connections. How does this not shunt the track circuit too (or maybe it does)?
View of railway tracks between a pair of station platforms. Taken to illustrate the fat cables leading to the substation, connected to metal bus-bars in the 'four-foot' of the track, to which several smaller cables connect each running rail.  This is all about providing the return path for traction current.

A newspaper cutting from the Staines & Ashford News, 13 August 1992. But what I want to know is, was the rumoured interaction (not mentioned in the article) true, or (sadly) was it apocryphal? Police: "Who do you think you are, Nigel Mansell?!" Senna: "No. Ayrton Senna." @joesaward.bsky.social
Newspaper cutting from August 1992, headline "Race ace Senna given driving ban", with subheading "Brazilian champ clocked at 121mph on M25".  Article "By Court Reporter".  Text of article reads as follows.

World motor racing champion Ayrton Senna was disqualified from driving for 28 days by Staines magistrates last week.

The 31-year-old Brazilian was not in court. But he pleaded guilty to speeding on the M25 through his counsel, Russell Davidson.

Peter Zinner, prosecuting, told the court that on the afternoon of Wednesday, June 24, an unmarked police car equipped with a video speed-checking device saw a Porsche travelling at high speed on the M25 from the direction of Chertsey towards Staines.

"The police officers checked the speed of the Porsche by means of the video until Junction 13 at Staines and speeds of up to 121mph were
recorded," said Mr Zinner.

"Mr Senna's vehicle was stopped and he was told that he would be reported for speeding. He made no coment [sic] and produced a
Monaco driving licence."

Mr Davidson told the court that Senna, the Formula one world champion, had only just hired the Porsche and was hurrying to a meeting.

"He is an important figure in the motor racing world with a large number of appointments to keep," said Mr Davidson.

"On the day in question he was on his way to keep one of these appointments and was unfortunately a little late.

"He accepts, however, that this was no excuse for speeding and he wishes through me to apologise to both the police and to the court."

Mr Davidson said while he accepted that the policy of courts was to consider disqualification for speeds over 100mph, he appealed to the court not to disqualify Senna.

In addition to the 28-day disqualification Senna was fined £250, with £30 costs.

Scan of the heading from Ayrton Senna's obituary in The Times newspaper on 2 May 1994: "Ayrton Senna da Silva, Formula One racing driver and three times world champion, died yesterday after a crash in the San Marino Grand Prix aged 34. He was born in Brazil on March 21, 1960.

I’m amused at how many private aircraft are taking advantage of the current closure of Heathrow airport to come fly over it in daylight hours — like this person I heard overflying a few mins ago, making a long afternoon’s flight from the Isle of Man just for the novelty value.
