Here is one example. It is not the best example however as the linking wire has been strung over the sleepers.
Some old copies of Model Railroader should show the part of John Armstrong's layout that used s/c.
By the way, the s/c system is self cleaning due to the sliding skate, hence its popularity for outdoor layouts. The skate (or ski if you like) will probably wear out in time but I know some with more than 50 years of use.
This part of that club layout has since been converted to solid centre third using brass wire similar to track on the right of shot.
This b/w shot from a Victorian layout from the 50's shows the idea at its best.
