Where was it built?
Japan, by Kawasaki and Hitachi.
This comes from the existing train catalogue. Exact factory and build-batch details still need a dedicated source check.

E6 Shinkansen
Komachi
Komachi is a red Shinkansen designed for journeys to Akita in Japan. Its narrower body fits the converted conventional railway as well as the high-speed line. The same train travels at different speeds on different sections.

What makes an electric train electric?
A collector takes electricity from the overhead wire. Electrical equipment prepares that power, and motors turn the wheels.
- 1The streamlined noseAt the front
A smooth nose helps the train slip through the air. The driver looks out through the dark windscreen above it.
Look deeper
A narrower Shinkansen designed for through-running to Akita. It reaches 320 km/h on the Tohoku section, but only 130 km/h on the converted conventional Akita line.
- 2A place for passengersInside the car body
People travel in the long car body above the wheels. Windows, doors and the connections between cars are useful clues on the outside.
Look deeper
This is an electric multiple unit: propulsion equipment is distributed through the trainset. Passenger space sits above the underfloor systems. Only three representative cars are shown.
- 3An arm that collects powerOn the roof
This spring-loaded arm touches an overhead wire and collects electricity for the train.
Look deeper
The roof collector is called a pantograph. High-speed electric trains normally take their traction power from overhead wires. Its position here is a teaching example, not an exact car-by-car equipment plan.
- 4More than just wheelsUnder the body
A bogie is the frame that holds a group of wheels. Springs help make the ride smoother.
Look deeper
Wheelsets, suspension and braking equipment form part of the running gear. Powered bogies also carry traction motors. This simplified model does not reproduce a specific bogie or show every motor and brake.
- 5The equipment below your feetBelow the floor
Electrical boxes help turn electricity into the power the motors need. They share space with other equipment underneath the train.
Look deeper
Transformers and power electronics condition electrical power for the traction motors. Different cars carry different equipment; these boxes show the general underfloor zone, not the exact position or contents of each cabinet.
Get to know E6 Shinkansen
Why can it go so fast?
A narrow body lets Komachi use two different kinds of railway.
Its motors and streamlined shape suit fast running on the Tohoku Shinkansen. Its smaller body also fits the converted railway to Akita, where it must travel much more slowly.
When was it built?
Passenger service began on 16 March 2013.
This is the debut of the train type, not the construction date of every E6 set.
Where does it run — or where did it run?
Japan: the Tohoku and Akita Shinkansen routes.
Komachi travels between Tokyo and Akita. The same train can have different speed limits on different tracks.
Is it still running today?
Yes — JR East lists the E6 for passenger journeys.
Look for the name Komachi. This fleet-level answer does not promise a particular train on a particular departure.
Fleet-status check: 2026-09-17. Consult the operator for departures.What are we still researching?
We leave gaps visible instead of guessing. The original catalogue and our learning model do not establish every real-world specification.
What is it made from?
A train uses different materials for different jobs: metals for strength, glass for windows and insulating materials around wires. Paint colour cannot tell us whether the body underneath is steel or aluminium.
How power reaches the wheels
Follow these steps, then find the matching sections in the model above.
- 1
Wire & collector
Electricity reaches the train from overhead.
- 2
Electrical equipment
It controls the supply reaching the motors.
- 3
Traction motors
A motor turns electrical energy into movement.
- 4
Wheels
Powered wheelsets turn against the rails.
Read the wheels
Look underneath: wheelsets support the train and carry the forces used to accelerate and brake. The model simplifies the real running gear.
What does its speed really mean?
320 km/h on the high-speed section. The Akita conventional-line section is limited to 130 km/h.
- Route context
- Tohoku Shinkansen section
A fast train is a whole system: vehicle, track, electricity or fuel, brakes, signalling and trained people. A race in the game is a simplified comparison.
What curious kids ask
Is the pointy nose what makes it fast?
The motors provide the power. A smooth shape reduces air resistance, and on trains such as the E5 the long nose also softens tunnel pressure waves. Fast travel depends on the track, brakes and control systems, too.
Does the driver steer like a car?
No steering wheel is needed to choose a direction. The rails guide the wheelsets. At a junction, movable sections of rail called points or switches guide the train onto another track. The driver controls speed and braking.
Why can’t it stop straight away?
A moving train has energy. Brakes must remove that energy to slow it down. A heavy train travelling fast needs room to stop, so railway signals help keep trains safely separated.

Bogie / truck
A frame holding wheelsets beneath a vehicle. It can turn relative to the body to help the train follow curves.
Gauge
The distance between the inside faces of the two running rails. Narrow gauge means closer rails; loading gauge describes the space a train may occupy.
Pantograph
A folding roof collector that stays in contact with an overhead power wire.
Traction
The force used to pull or propel the train. Grip between wheels and rails limits how much force can be used.
Multiple unit
A train with propulsion equipment within its passenger vehicles, operated together from one cab.
Locomotive
A powered vehicle whose main job is to move other railway vehicles.
Shunting / switching
Moving and arranging vehicles in a yard, often at low speed.
Livery
The colours, stripes, logos and other markings painted or applied to a train.
Service speed
The permitted speed for passenger or freight operation on a suitable section. It is not the journey average.
Record speed
A speed achieved on a particular test or record attempt, sometimes with special equipment and conditions.
Tender
A vehicle coupled to a steam locomotive to carry extra water and fuel. A tank engine carries water on the locomotive itself.
Prototype
An early vehicle built to develop and test a design before a production fleet.
