I happened to travel part of my journey last weekend with a so-called 'green train'. It's a project with which the Dutch Railways (NS) will make all their electric trains ride on wind energy from 2018. Wind mills are built more and more in the Netherlands. As the project is continuing, about half of the trains are already -as we call it- 'climate neutral' by now.
Instead of the usual yellow/blue trains that NS owns, they catch attention for their green train project by using this colourful design.
