How long is my Dutch NS train?

So you're in the Netherlands, waiting for your train. Wouldn't it be easy to know what length the incoming train will be? So you can wait apart from the crowd, board easily and have a comfy seat instead of having to stand the whole trip.

Now you have the info, all you have to do is pick a spot on the platform!

The Treinlengte-app shows the closest NS-stations near you. You choose a station and the app will show which trains are expected to arrive, including their length. No suprises there, how cool is that :)

PS: The app is still in beta, however it's free to use for everyone!
PPS: The data come from NS and NDOV/OpenOV
