In addition to what they said... "Shinkansen" literally translates as 'new trunk line'. The track was specially constructed for the exclusive use of the new trains. The network now includes small sections of track that are shared with normal commuter trains, where the speed limit reduces to 130km/h.
Every centimetre of Shinkansen track is examined every night between approximately 00:00 and 06:00, which also precludes use by other services. The ride is sublime. You have little sense of speed until you pass another train.
The acceleration from stop is smooth and you can move around without holding on for dear life. Between Tokyo and Osaka, the speed limit is 270km/h because of the radii of the corners. Between Osaka and Hakata (Fukuoka) the 300km/h speed limit is imposed to minimise noise.
For example, the top speed of the Series 500 in service is really 365km/h. Tests have been conducted at 350km/h but we may have to wait until a new model for those speeds. The Linear Shinkansen hit ... 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.
