If you are wondering why the Scots value the EU more than the UK then I would say this is one of those reasons. It is like the north and west side of the island doesn't exist in parliament. Most of the investment in infrastructure is going to Southern England and the rest of the island gets the crumbs left over. The funding is disproportionate yet there is more room for growth in the other parts of Britain.
If it was my choice, I would build frames above the railway tracks that support solar panels and small compact wind turbines, that would bring down the cost of running the railways because the sunlight shining on the solar panels would contribute to the power of trains and I would make sure that every last bit of tracks are electrified before I build a single railway on the island. There shouldn't still be diesel powered trains running on this island, they are slow to accelerate and can't go as fast as electric trains. Diesel trains are more heavy than electric trains so they put more pressure on the tracks and shorten the lifespan of the tracks more than electric trains I think.
I get things wrong often but right now that is what I think. I am only writing the truth from my perspective. No facts are on this post just an ordinary man's opinion.
