It appears that the semaphores in the RWA route are made by G-traX, and that while I can reference them in my own route, they aren't among the assets I'm allowed to redistribute.
No worries, just making it clear that I know all that...
My question is, did they ever make a Home/Distant version?
Also, were they made for / distributed with the Stevens Pass route? (I noted that the <product> tag was StevensPass)
