Minecart control panel

For all of you out there that like to build minecart stations, here is a control palen circuit that is very compact!
Space is always a problem for me when building things, since I am not planning much when I start building I often end up with circuits that are way bigger then they have to be.

But HERE you have a really compact circuit for a multi-destination control.

This is how compact it is. Most of the wireing is underground here but the cut through chematics looks like this.
