Are two aspect semaphore bushes a thing? :P

It is a long time since I have done any serious editing but I used "dummy yard signals" intensively. I don't see their provision as un-prototypical, not do I see any need for "real" drivers to obey them. You can bury their little one-aspect bush below ground if you wish. I think somebody on here made a completely invisible one a few years ago but personally I preferred the little weed there as a marker/reminder to me that I had remembered to put one in!

As I see it their purpose is to solely to serve AI traffic. If you have a large yard, separating each siding off by having a DYS at each end will avoid all scheduling errors showing consist clashes and will allow several trains in the yard at once. It will allow, for instance, a shunt to take place and when (and only when) the shunt has reversed clear into its destination siding), another train might depart on its journey.

If you don't follow me, a look at Mottram on the original Woodhead route will show you what I mean.

They can be used in other places too, and allow the total elimination of all those "static consist errors" that appear in the scenario editor, ensuring a collision-free scenario.
