Whilst we don't have services as fast as those of the TGV, we have services on 'classic' routes that now run regularly at average speeds of in excess of 100 miles an hour, where you can just 'turn up and go'. Even in 1975, when I started to travel regularly between London and Newcastle, the journey time behind a Deltic was 5 hours - HSTs and later electrification got that down to 3 hours. Similarly, with routes to Wales and the West Country using HSTs.
Speeds on cross-country services increased out of all recognition with the introduction of Voyagers and Super Voyagers, with regular interval services on routes that had perhaps only a couple of trains a day (eg North East to South West). Speeds on the west coast route to Lancashire and Scotland increased with Pendolinos, and are due to increase even more when the route upgrade is finished... So, please don't listen to the half baked prejudices of most of the previous answers which talk without regard to the facts. Beeching had nothing ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
