The problem with trains is they are public (under)founded. The rich and powerfull with political influence don’t want working public transportation because less carsales, oil, gasoline etc.
Which explains why Musk prevented a high speed train in the US with his hyperloop. We all need to buy EV"s which have most of the downsides of traditional cars.
When we could have clean, fast and comfortable public transportation.
EDIT: Spelling.
I use posteo.de, and are very happy with it.
