>I took a ride on #14 up the Coast Line many years ago. I noticed in many places we would pass an opposing direction ABS signal and it would display a yellow or flashing yellow behind us, despite no trains following behind.

How do you know there were no trains following behind or a local which had lined itself out onto the main line after #14 went by?

>Why wouldn't it immediately display a clear if the blocks behind us were empty?

This would be the expected behavior, but the removal of sidings without rewiring the signal system could have had some effects too. At this remove in time, it's more than likely impossible to tell.
