Above the railways of bullet trains...Ueno-Tokyo Line.

On purpose of the enhancement of convenience for customers,


mitigation of exaggerated rates of passengers on train and


bolster for conveyance and fluent diagrams...JR finally decide to


build this additional lines above the Shinkansen...


that connected the Tohoku Line and


Tokaido Line...thus, the Ueno and Tokyo Sta.


Both were formerly departed because the lines between them


were used as temporary garages and could not use them...


Some trains from North Kanto area to South Kanagawa area


are available as Shonan-Shinjuku Line (via Yamanote cargo line,


through some major stations in Tokyo)


Those are the substitution for direct lines between them...partly.


However, it is not substantive for replacement enough....thus,


they determined to construct the project of Ueno-Tokyo Line...



As you see, from Tokyo to Akihabara(passing), the railways are


going up...above the bullet trains' ones...hence, the scenery is


so high and interesting...before passing Akiba, the altitude of


railway is same as the proximal ones...and continue that height


to the Ueno...



When the lines are open, the efficiency and convenience of


connection between Tohoku and Tokaido Lines surged....


people do not have to take off in Ueno and Tokyo to reach


both station by layover to other trains...especially Yamanote


line and Keihin-Tohoku Line...which both were much crowd and


sometimes late because of that...moreover, other major lines began


to use the lines...to go to Tokyo for convenience for passengers...



Nevertheless, there are also negative sides of them....because of


the intricate points in Ueno Sta. that was shared


by plural lines....sometimes it causes some delays against diagrams...


Moreover, some passengers were confused because of some changes...



Anyway, this would be the savior of excessive boarding rates and


convenient diagrams...especially for commuters in business weeks.
