Your rail system is already pretty advanced, compared to ours, because we have so many places with too few people living there. So in the States, you have High Speed from Washington to Boston (Acela) and a Midwest Corridor from Milwaukee to St. Louis that see a lot of trains, and the rest of the network is about 2 trains a day until Trump and his Amtrak scrapper Rick Anderson have their way. Political governance for Amtrak will keep Amtrak behind the times and behind the curve for as long as it continues. Because even though a Republican (Nixon) initiated Amtrak (because the private railroads didn't want passenger service without mail contracts) ((and were doing a p*ss poor job of running railroad passenger service, anyway)), every time a Republican administration gets in, Amtrak winds up on the block, in some way shape or form. Your passenger service, although lacking proper air conditioning, is a fine service light years ahead of ours, just as it stands. Of course, Great Britain is about the size of the American States of Illinois, Wisconsin, and Iowa. But the only reason we have decent rail service in the Midwest is because the states of Illinois and Wisconsin themselves fund much of it.
