New Railway

It is the last part of May 2022, about a week away from the Queen's Platinum Jubilee and a new railway has opened. They call it crossrail and the Elizabeth line. It is a bit like Thames Link but it goes East to West instead of North to South. They are different from most the trains in London, they use overhead power lines to power the train so I imagine it would be very quiet inside. The trains look very modern and sleek, they accelerate very quickly and the station platforms look very big and modern. The railway goes from Reading to Shenfield and passes through central London with a branch that goes to Heathrow airport. It connects towns near London and also connects more stations in London together. 

When I see news about railway projects in the UK the first thought that comes into my head is why they don't use the existing train lines to gather renewable energy. They could build a box frame around the train tracks, the top of the frame would have solar panels and the sides of the frame would be a mesh like grill similar to the front surface of  sound speakers. The sides of the frame would have wheels in it with fan blades that harnesses wind energy. When the wind blows, it pushes against the wall of the train frame and makes the wheels with fan blades spin, the rim of the wheels would have magnets in them that passes across copper coils, this would cause electro-magnetic induction. I imagine the draft from the moving trian would also cause the wind wheels to spin.  The main revenue of the trian lines would be to harvest renewable energy and the secondary revenue would be to transport goods and people. This thought always comes into my mind when I see news of railway projects in the UK.
