base stats
Bars compare against all trains: 600 km/h (maglev), 1,700 seats; power, weight and number built on a log scale up to 20 MW, 1,000 t and 20,000 built.
fun facts
- First built 44 years ago, in 1982.
- Top speed is 1.2× a car on the Dutch motorway (130 km/h).
- At full speed it would cover Amsterdam–Utrecht (≈ 40 km) in 15 minutes.
- 4 MW is about 47 family cars (~85 kW each) flat out.
- Weighs about as much as 14 African elephants (~6 t each).
- 15.5 m long: about 3 cars parked nose to tail.
electric locomotive: Draws power from overhead wires or a third rail and pulls separate carriages.
