Do you have any other heating, apart from gas central heating? or electric heaters.
If not it might be worth buying a portable heater that uses paraffin or bottled gas. And fuel for at least a weeks heavy use.

Any serious crisis is liable to interrupt electricity supplies, as a lot of our electricity is still from gas.

With a new war well underway in the ME, it would be well to review and perhaps to increase stocks of oil derived fuels.
Not just petrol, but also diesel, heating oil, paraffin, and LPG^▸ (Liquefied Petroleum Gas).

Shortages are possible, esp. if the situation escalates.

Petrol storage is limited to 30 L. It should not be stored in living accommodation.
Butane storage within a home is limited to two cylinders each of 15 kilos or less, no limit on outdoor storage.
Propane should not be stored in a home, no limit outdoors.
Almost any volume of paraffin, diesel fuel, or heating oil may be stored.

A war in the ME is most unlikely to affect supplies of coal and fire wood, but shortages are possible if people use extra coal or wood in place of other fuels that are scarce or expensive.

I agree, but am still surprised that the military authorities allowed this. I support HM forces and have no problem with such forces carrying weapons.

As they were presumably still capable of breeding, not eligible for a Darwin award.
To be eligible for a Darwin award, a person must be unable to pass on their obviously defective genes. This may be achieved by death, or less commonly by destroying or removing the breeding equipment.

Possibly an honourable mention instead.

One of my favourite Darwin awards was an American whose car radio ceased to function due to a blown fuse, they used a live rifle round as a substitute. In time the passage of current fired the round, which removed or destroyed the breeding parts.

I am a bit surprised that troops were allowed to carry rifles at a major station, and on the train.
I appreciate that HM forces presumably have an exemption that permits the carrying of weapons in public, but am surprised that it was done in peacetime.

Poles for floodlighting usually had only two wires, possibly more in very extensive installations. If arc lamps were used there was usually a winch to lower the whole lighting unit to near ground level for attention, as this was needed frequently. For filament lamps, or later mercury lamps, a ladder was often provided for lamp replacement.

A few installations used series lighting, whereby special lamps of low voltage were used in series on a high voltage supply. Never popular in the UK^▸ (United Kingdom), more of a USA thing.

It is possible that some of the wires shown are not for railway purposes, but are part of the local telephone system.
Since the right of way and the support poles already existed, it was often economic to use the existing infrastructure for phone lines, rather than building a new route.
This was done in the UK^▸ (United Kingdom) and overseas.

A minority of UK telegraph line routes along railway lines had red insulators. These were used for a mains voltage electricity supply to remote signal boxes. Only a small current was available, limited to lighting and sometimes to battery charging.
Space heating and cooking was generally by coal or paraffin.

I always felt a bit uneasy at killing large numbers of beetles, not for some important medical purpose, or even as food, but simply for a decorative colouring agent.

I see no need for trains to have frequent battery exchanges, and probably no need for any exchanging of batteries in normal service.
Presently available lithium batteries  can give a battery train a useful range of hundreds of miles, no one is going to adopt the new and relatively untried sodium batteries unless these can give a significant improvement on this range.

Physically swapping batteries sounds like a lot of moving parts and extra failure points.

Fast charging the batteries in situ sounds a lot more sensible, and can be automated. Should be simple and reliable, with sufficient battery capacity so as to permit of at least two consecutive fast charges at stations being missed without any reduction in performance.

Splendid ! Would never be allowed here, what if children, or hard of thinking adults climb out.

About a dozen injured, some seriously. A suspect has been arrested.

ETA later reports state 17 injured.

That is cochineal, used until recently as the colouring agent in Campari.

Later reports state that the driver of the tractor was arrested on suspicion "of endangering lives on the railway"
One person taken to hospital by air ambulance, and another by land ambulance, many others treated at the scene for minor injuries.
The train remained on the track and does not look badly damaged. Probably drivable under its own power, at very low speed to a depot for repairs.
The tractor looks still useable. the trailer is substantially destroyed.

IMPORTANT EDIT. Other reports have contradicted my post. Some reports that a signaler was arrested and NOT the tractor driver. See later posts for details. My source was local radio news.

Several persons injured, though reported to be not life threatening.

Long term update.
Tests and investigations continue, and as a result I was prescribed a new (to me) drug. Colchicine.

This medicine seems effective.
