Do we know for sure that the tracks aren't ballasted? Keep in mind that the ballasts could be covered by concrete after they've been installed. That's how the TTC does them for streetcars:
View attachment 43685
The only stretch of ballasted track on the TTC streetcar system is the section between Humber Loop and Sunnyside, along The Queensway. Everything else is rail encapsulated in concrete.
What you are showing in that photo is the rail attached to the ties, sitting on the cured, poured concrete slab. The nest layer covers the ties, and the third fills up to the top of the rail.
