Comparison between the Shinkansen and the French TGV

Shinkansen and Tokaido

Gauge	1,435mm
Body width	3.4m (previous width 3.0m = reduced construction limit)
Allowable axle load	16t
Electrification method	, using single-phase AC 25KV, 60Hz (the power grid east of the Fujikawa River is 50Hz, so it is converted to 60Hz using a frequency converter). However, due to differences in electrification methods, the tracks on the Tokaido Line are not connected to those on the Tohoku and Joetsu Lines, and there is only one platform with two tracks, which handles Tohoku and Joetsu Shinkansen trains.
For trains only	・Reduces the weight load on track beds and bridges ・Simplifies track wiring at stations and depots
traffic lights	Systematization of all train operations ・Development of Automatic Train Control (ATC) ・Adoption of Centralized Train Control (CTC) (Train positions are monitored from the central control room, and station switches are also remotely controlled from the control room)

Eurotunnel

Gauge	1,435mm
Electrification method	Single-phase AC 25KV, 50Hz overhead line
substation	・Folkst 132KV ・Fletton 225KV
Feeder	erection tunnel within the work tunnel (if one of the substations goes down, the other substation will extend the power supply and provide power. In this case, the train speed will be reduced to reduce the load on the substation). The electric system covers all the electrification systems of the railways that the line operates on: SNCF and undersea tunnels use AC 25KV, 50Hz, SNCB uses DC 3KV, and BR uses DC 750V third rail (these are switched while the line is running). - For use on conventional lines: 2 electric types (25KV AC, 50Hz and 1,500V) - For use in Switzerland: 3 electric types (25KV AC, 50Hz, 15KV AC, 16Hz and 1,500V DC) - For use in Belgium: 3 electric types (25KV AC, 50Hz, 1,500V DC and 3,000V DC)
Signal system	・Uses the same TVN430 as the TGV-Northern Europe line ・Train route control is computerized except in emergencies ・Maximum number of trains that can be operated is 20 per hour in each direction
Body width	2.8m (the smallest BR vehicle clearance applies)
locomotive	Driven by a VVVF inverter-controlled induction motor using a GTO (a powered bogie is also installed next to the passenger bogie) (Locomotive mass 68t, axle load 17t)
traffic environment	The area of France is 1.6 times that of Japan, of which the plains account for about 80% and the population is half, so the population density in the plains is about 1/13 (almost the same as Hokkaido).
