Why is Federal government at fault, and not, you know, the rail company that owns the railroads and collects the revenues?
Are you really a pilot? You should know better than to treat blame as finite and indivisible.
Of course it is feasible, but the transit corps are only interested in maximizing profit and the government backs them up. They could run these trains with 10x the crew, with full top-tier benefits, and still turn a sustainable profit. But right now these companies are being run as paperclip maximizers and merely sustainable profit isn't good enough for them.
