I wanted a cross over that didn't have a straight through option, so trains would always cross over to the other side of the track, so I modified the original to suit my specifications.
I've also applied a fix to the track to allow it to suit the Ikea Lillabo track better
The author remixed this model.
Removed the straight through tracks so the train always crosses over
also tweaked the keyhole end to better fit the Ikea Lillabo track
