It was just a (clever?) play on the blue circle plaques and Venn diagrams. 
Hardly worth analysing to the nth degree.

I managed to get myself ready and set off early for my 3pm in Leigh on Sea for my hearing test. The sound proof box was faulty but they have portable units for home visits. Anyway the test went well and pretty well confirmed by own belief/observations of the state of my hearing over the last year. It was however not just a case of boosting the default amplification but tweaking certain frequency bands. 
I got a cup of tea and a biscuit too!

The ‘tweaking of certain frequency bands’ in some modern hearing aids outperforms many top of the range graphic equalisers that cost and arm and a leg a few years ago.
 

Apart from the overall amplification I notice a huge improvement un the clarity of what I hear.  My (lack of) frequency response is a result of, and typical of, me having measles as a youngster.

IIRC, the average European of today has something like 3 - 5% Neanderthal DNA.

 

Dave

That’s most reassuring given that we share about 50% of our DNA with a banana.

The steam loco they use has broken down at least once.

Did it break down or just have problems with adhesion.

at some point I find the solutions more obnoxious than the problem and would prefer to live with the risk

That is fair enough if it were only you involved and happy to take the risk.  Others (the majority?) might prefer to have mitigations put in place to reduce that risk. I know you were speaking in more general terms, but  I wouldn’t like to be the one hit by a moving open door because someone else found fitting CDL ‘obnoxious’.

… but only if they don’t paint them in that blue.

BoD I thought Clockman was  referring to the arrangement where a relay is energised then one of its own set of  contacts maintains the energy to the coil.

Such an arrangement  requires a current  through the coil.  The interruption of that current by pressing a normally closed push button then switches the relay off.

 

 

Are you referring to some kind of mechanical  latching? How is such a relay then switched off?

Others have replied but RS-online has a useful explanation - again, as others have said, it may be a case of the terminology being used.

A latching relay requires a constant current which the cdu  won't give.  I suppose  it would work with a twin coil relay of some sort  using a second supply to keep it latched. 

Sorry Colin, a latching relay does not require a constant supply once activated - hence the term latching. They are switched on and off by pulses of current.

Definitely need some TV company to a fly on the wall documentary about WCR's management......

Except they would somehow manage to come across as the wronged party and twist it into a tale of David v Goliath. 

Wouldn’t it also mean issuing/re-issuing an exemption.  Not very likely.

Interesting video, Andy.

Is that the line where there are market stalls alongside too?  The line seems totally blocked but when a train is due goods are pulled back and canopies folded in.

I wonder what ORR would make of the compartment droplights. As I recall, the window slid down to level with the washbasin cover and you could basically sit with your whole body out of the window.

Easier than going down the corridor to the somewhat cramped toilet.

I have just been reading the Telegraph article. The view of the Telegraph readers is that the nanny state is getting in the way and that WCRC should be allowed to get on with it.

Well there’s a surprise.

Back in 1975 Aditi spent ages making handouts with lovely maps or landform diagrams for her geography students. When I did my PGCE at Keele there were courses all about classroom technology , Banda copiers, stencil cutters and how to make clever ohp slides with overlays. Also how to use a video tape (not cassette) player and film projectors. Eventually all that lot were replaced by computers. They also had some weird teaching machines that someone somewhere reckoned would replace teachers. They didn’t. 

I suffered a similar course, perhaps a couple of years after you.  By then we were not only encouraged to use video tape but to actually use video cameras (huge mains operated contraptions) to record our own presentations for use in our lessons.  They never told us that to actually use video tape in the classroom involved booking a system (the tv  with opening doors and a  Phillips Video player on a wheeled trolley thing)  via the schools AV technician, several weeks in advance.  It was at this point I realised that I wasn’t destined for an alternative career in film let alone an Oscar.
