Our job was to let people experience the difference between the old and new planning system for the Dutch railroads. We designed sound and music that leads you from the dripping basements and outdated machinery of yore, to an uncluttered and bright future.

Prorail - BTD planner


It’s getting busy on the railroads in the Netherlands. Therefore, train maintenance schedules need to be super tight. The previous planning system was outdated, complex and diffuse. New BTD software brings clarity to the process and puts ProRail back on the right track. We designed music and sound design that lets you experience the difference.

What we do

Sound design​

We create custom sound design for all kinds of media: from film to animation. We create our own sounds using synthesizers, foley and audio libraries.

Audio post-production

We edit, process and mix all individual sound elements into a well-balanced mix that meets the technical specifications your medium requires.


Whether you’re looking for a custom made track or a stock option: our herd has the best solution for your musical needs.
