Switch mechanism upgraded to EV3 L-motors

As mentioned in the article about the “Plans for Lego World 2015”, the switch mechanisms will be upgraded to the modular version. We use the L-motors since we have plenty of these left. This is how it looks:Upgrade switch mechanisms to EV3 L-Motor

We have four of these mechanisms: three for the marshaling yard and one for the delivery station.
