Consequently, nuclear-weapon states consider nuclear disarmament and the achievement of a world without nuclear weapons to be a long-term aspirational objective at best.
How much long is this long-term target?
For the last 10 years or so, there has been no considerable reduction in this number.
I would say it would be outside of the NPT that arms reductions occur.
All talks for disarmament were between the USA and Russia not through the Non Proliferation Treaty.
Even the Six Party talks didn't involve the whole council.
The reason that it is done this way is because to many parties mean nothing will be done
The recent talks now are between Iran the USA and Russia are an interesting example though

A similar study was made for trains a couple of years ago, and for trains is by far more logical and the plan was to have a roof running all over the railroads which will produce electricity that will be injected to the train network, but the study showed the amount of solar panels needed for the needs of one train is HUGE not to mention from investment stand point it was viable at all.
I think the best way to deal with carbon is to think about decentralized energy, the Sahara desert for example offers an illimited potential in terms of Thermosolar and solar ray concentration power (not so in terms of photovoltaic as these require a lower temperature for optimum power delivery (around 21°C) which can be good in northern Africa, southern Europe and similar thing can be made done NA region) the energy can be then exported to EU, and you'll have carbon free energy (from a production perspective at least that can electrify Africa and europe ! and for the cheap
Agree from a feasibility standpoint weathering is a serious problem, when the temperature changes rapidly etc. There is also the concern of heavy rainfall or how it would work with its electrical line if the thing is flooded. Waterproof wires perhaps but that raises questions as well on how much underground wiring is needed beneath the surface and how it generates energy if one part is broken aka the circuit stops
(Similar to Christmas lights where if one lightbulb is broken the energy isn't passed on past that lightbulb but works to the breaking point)
It raises many questions on how it would work in practice that said it could work so its still worth analyzing. Perhaps they can find solutions.
I didn't know that it was considered for Trains but that makes sense to me, the costs may be too high presently but as costs go down and production increases it may work in the future. Neat idea thanks for sharing that.
And decentralized energy, well we do use a decentralized system with Bitcoin so I can see that becoming a natural extension of energy, and bringing about illuminated revolution
