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	Single-phase AC 25KV, 60Hz (converted to 60Hz using a frequency converter because the power system east of Fujikawa is 50Hz). All Shinkansen lines connect at Tokyo Station. However, due to differences in electrification systems, the tracks do not connect the Tokaido Line with the Tohoku and Joetsu Line lines, and there is one platform with two tracks to handle Tohoku and Joetsu Shinkansen trains.
For trains only	- Reduces the load on track beds and bridges. - Simplifies track layouts at stations and train depots.
traffic lights	The systematization of all train operations , development of an Automatic Train Control (ATC) system , and adoption of Centralized Train Control (CTC) (train locations are monitored in a 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 • Freton 225KV
Feeder	Within the work tunnel, sections for power supply divisions are installed at the entrance to the temporary tunnel and in the center (if one of the transformers goes down, power is extended from the other substation to provide power. In this case, the train speed is 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 operation on conventional lines: 2 electric systems (AC 25KV, 50Hz and 1,500V) - For operation in Switzerland: 3 electric systems (AC 25KV, 50Hz; AC 15KV, 16Hz; and DC 1,500V) - For operation in Belgium: 3 electric systems (AC 25KV, 50Hz; DC 1,500V; and 3,000V)
Signal system	- Uses the same TVN430 as the TGV-North Europe line - Train route control is computer-controlled 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	GTO-based VVVF inverter-controlled induction motor drive (a powered bogie is also installed on the passenger car bogie next to the locomotive) (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).
