There will always be a need for some coal, whether imported or produced domestically, for iron and steel manufacture.
It should be simple to use a little for heritage railways.
There is also a modest but ongoing demand for coal for domestic heating and cooking. The domestic use of traditional housecoal has been/is about to be banned, but anthracite and coal derived patent fuels are still permitted. It should be simple to use a little of this coal for heritage railways.

Also coal burning for electric power production is unlikely to permanently end just yet. It is expected to resume in the winter, and for the next few winters. It should be simple to divert a little of this power station coal for heritage railway use.
Electricity from coal is declining rapidly but is most unlikely to become totally extinct just yet.

Farriers and blacksmiths will also need coal in modest volumes for the foreseeable future, supply to heritage railways could be combined with supplying this market.

When I was working in London, there were two somewhat related reasons for taking a black cab when the underground would have been cheaper and greener.
Firstly my work involved the carrying around of a small tool kit that included a Stanley knife or other "bladed article" I felt it prudent to avoid LUL^▸ (London Underground Ltd) services due to the risk of having to pass through a "knife arch" or be subjected to a random search.
Whilst the carrying of a small pocket knife or craft knife in a tool box as a tool of ones trade sounds lawful, PCSOs tended to take a different view and I did not care to be arrested and prosecuted, even if later acquitted.
My concern was well founded because a co worker HAD been arrested and charged with carrying an offensive weapon. They were acquitted, but faced months of worry, legal expenses, and loss of wages. Their temporary contract was not renewed allegedly because "being arrested for carrying a weapon" was looked upon with disfavour even if not convicted.
A lot of taxi fares can be paid with the money not spent on legal costs.

The other hazard of underground or bus travel was being refused admission for "carrying alcoholic drink" The actual prohibition was on drinking or carrying open containers of drink. But some staff over interpreted the rules and refused passage to anyone carrying shopping that included alcoholic drink.
Simpler to take a taxi.

On the underground I also had a slight fear of inadvertently breaking the rules surrounding oyster cards and being done for fare evasion. Life was much simpler in the days of a printed card tickets.

No worse then hunting for the static trolley, and repeating the exercise in case it has come out of hiding later in the journey.
No worse than a mobile trolley that has to go past everyone.
And some movement along a train is unavoidable if customers are to use the toilets, stow cycles, look for their reserved seats, or look for vacant seats, and alight at short platforms.

How about a buffet counter ! with a plastic screen to protect staff and customers from each other, and hand washing facilities for the staff, and alcohol hand sanitiser for the customers.
Well ventilated with the fresh air being filtered.
Place this facility between first and standard class in order that each may use it.

With careful planning the risks to staff and customers would be no worse than those prevailing in supermarkets, take away food outlets, off licences and the like.

Certainly good news for the environment, electric trains are the way forward and are arguably getting ever greener as a growing proportion of UK^▸ (United Kingdom) grid power is from renewables.

Despite this, I support the principle of bi-mode trains for when the wires come down, and for flexibility of use on routes not electrified.

I have slight misgivings about the renewal of the pumping station. I have a slight fear that new pumping plant may be over complicated and reliant on computers and software, and therefore less reliable than old, and that the tunnel might fill with water because "computer says no"

Without pumping, how long would it take for the tunnel to flood dangerously ? I have heard only a few minutes, but can not substantiate this.
Does anyone remember all the new trains that failed during a brief and entirely foreseeable drop in the grid frequency ?
And Ipswich hospital that suffered a total blackout for the same reason ?
One might hope that new pumping plant wont suffer likewise.

A great many passengers consider that current fares are too complex. I hope that the coronavirus emergency will not be used as an excuse to add an extra layer of complexity.

Many passengers consider fares to be excessive if compared to those charged overseas, or for services considered to be getting worse not better. I hope that the coronavirus emergency will not be used as an excuse to further increase fares.

"This service has a static guardian angel, found between coaches B and C"
"The guardian angel is in the other portion of this service."
"This service will be cancelled due to guardian angel shortage."
"Guardian angel is self isolating in the kitchen"

If the lamp pictured in the report is one of the ACTUAL lamps that caused the interference, then yes it would appear to be a modern reproduction of an older type of tungsten lamp.
A mains voltage voltage tungsten lamp needs a filament of considerable length. In modern lamps this is coiled, and sometimes the coil is again coiled, so as to fit easily into the bulb.

Older types of tungsten lamp, and modern reproductions thereof, did not coil the filament but instead arranged it as a complex zig-zag up and down the bulb. Correctly known as a "squirrel cage filament" and favoured for ships navigation lights as well as decorative uses. Very wasteful of electricity.

In view of the poor standards of technical reporting these days, I consider it possible that the lamp illustrated is NOT the actual lamp but may be a library image found by googling "vintage bulb"

If the picture is accurate, then yes, squirrel cage filament lamps CAN cause radio interference. Parts of the lamp can function as a very crude thermionic valve and may oscillate and radiate interference. This is well documented in old textbooks dating from the era when such lamps were popular.
Apparently trivial differences between one lamp and another, well within normal manufacturing tolerances, can result in some examples radiating interference whilst others do not.

Alternatively, the actual lamps involved might have been LED types, with strips of LEDs arranged so as to somewhat simulate a squirrel cage tungsten lamp. The LEDs cant produce interference, but the switched mode driver circuits can be a cause of significant radio interference.

In either case, the interference radiated DIRECTLY from a relatively small lamp is unlikely to be significant. The supply wire to the lamp can act as an aerial, and if fortuitously aligned, high up, and of the optimum length could radiate significant interference.
In most cases I doubt that it would be significant, but with a sufficient number of lamps in use, eventually some particularly bad examples will end up in a loft conversion, under a flight path, and connected to wire exactly the correct length to act as an effective aerial.

No good will come from these new fangled flying machines, nor from electric lights.

We should return to gas lights, oil lamps, horses, and steam powered railways.

I recall hearing that a "King" DID^» (Didcot Parkway - next trains) cross the Royal Albert bridge in the dark and contrary to the rules, owing to a mis-understanding.
There was considerable consternation when this was discovered. IIRC^▸ (if I recall/remember/read correctly) it was allowed back across the bridge, but uncoupled from the tender in order to reduce the total weight.

Is anyone able to confirm ?

Broadgage is well known for his liking of IETS, and particularly appreciates the flexible train length.
The (sometimes) trolley service is such a great improvement over a buffet. A static trolley is better still, and no trolley is the ultimate improvement. The limited range of goods, sometimes nothing at all, is very helpful for those trying to avoid weight gain or intoxication.

The seats might be slightly less comfortable than those in the older and now non compliant trains. They do however conform to the latest fire resistance standards, this should significantly reduce the terrible toll of passengers killed by spontaneous combustion of railway carriage seating.
Any discomfort felt for a small part of a long journey, by a minority of customers, may be totally alleviated by standing up for a while, which is so much healthier.

I am too old and fat to go climbing towers. I have a fear of falling off, and am also fairly law abiding.
I have however seen pictures taken  from atop the tower, they were, and probably still are publicly viewable. I do not feel it helpful to post any links to a site that blatantly encourages and glorifies trespass on railway and other property.

I have no objection to IET kitchens, and would defer to the views of the experienced Pullman crews. If the majority of such staff consider the new kitchens to be an improvement, then they are the experts and I respect their views.
However splendid the kitchens are, that does not justify the absence of buffets, the hard seats, and the frequent short trains.

For a small, urban, and perhaps not well known station, Nunhead in south east London has an excellent view in clear weather.
It is the highest station in London, and from the down platform has a panoramic view across central London and beyond.
St Pauls cathedral, the post office tower, the millennium dome, and many other sites are visible.

An even better view may be obtained by illegally climbing the newish radio mast at the London end of the platform. Despite the usual anti climbing precautions, the climbing of this tower remains popular with urban explorers.
I am not of course recommending or advocating such trespassing, it looks dangerous as well as being illegal.

This station has an island platform, and from the up side the view is less interesting but does include the (former) broadgage towers.

Yes, but I doubt that such modernity was much seen on the Minehead branch.
I have heard that some intermediate stations did not get electricity until a few years before closure.
One station still has a small hand operated winch intended for hoisting a Tilley lamp aloft after filling and lighting at ground level.
