Sometime ago I decided to make two of the spurs cross, creating a diamond (which can also be seen in the picture). This to create some visual interest. And for the opportunity to build a diamond, which I have never done before.
When now installing the tie strips I was forced to consider the diamond as well. I started by drawing lines where the rails would eventually cross. I also marked the position of the ties.
After having studied some pictures of diamonds on the Internet I realized that the ties needed to be diagonal to both sets of rails. Otherwise they would not be able to support rails in both directions at the same time. I arrived at the pattern in picture below.
