what is it?
The Sm7 is a class of 4-carriage electric multiple unit trains planned to enter service on the VR commuter rail network starting in 2026. The trains are based on the Stadler FLIRT platform (same as the urban Sm5 trains) and are assembled in Poland. They will replace the Sm4 trains on the D, R, T, Z and M routes which will in turn allow the non-accessible Sm2 trains to be retired entirely.

fun facts
- First built 0 years ago, in 2026.
- 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.
- Weighs about as much as 32 African elephants (~6 t each).
- 106 m long: about 24 cars parked nose to tail.
- Seats 796: 16 full city buses (~50 seats each).
multiple unit: A self-propelled train: motors are spread under the passenger cars, so no separate locomotive.
