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

TGV Euroduplex
TGV INOUI · 2N2
This French TGV was built by Alstom. It has two passenger levels, allowing more people to travel in one train. Separate power cars at the ends provide the pulling and pushing power.

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 double-deck TGV with separate power cars. This is the Euroduplex generation, not the original 1996 Duplex or the modified 574.8 km/h record train.
- 2A place for passengersInside the car body
These passenger cars have two levels! The windows help you spot where people sit.
Look deeper
The leading vehicle is a power car, not a normal passenger saloon. Passenger accommodation is in the coaches behind it. The three vehicles here represent part of a much longer train.
- 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
This train uses separate power cars. Much of its main traction equipment is in those vehicles. The boxes shown under a passenger coach are a generic teaching layout, not a map of its main traction system.

Why can it go so fast?
Electric motors supply the push; a smooth shape helps it move through the air.
Fast running takes a whole system: suitable track, reliable brakes, signalling and power. A pointy nose alone cannot make a train fast. Stopping at stations also makes a journey’s average speed lower.
When was it built?
2011 — service debut.
Catalogue milestone: 2011 · first delivery. A delivery, a first test and a first passenger trip are different events. Individual vehicles can be built in different years.
Where does it run — or where did it run?
French high-speed routes and compatible cross-border services in Europe.
This is the route context in the existing catalogue, not a live timetable. Current assignments and stopping patterns still need a fresh operator check.
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.
Is it still running today?
Old photographs and launch announcements do not prove that a train still runs. A whole class may still work even after one member retires. We need a recent operator or museum source.
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?
Alstom specifies up to 320 km/h for Euroduplex, which entered commercial service in 2011. Record runs by specially modified TGVs are excluded.
- Route context
- French high-speed lines
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.
