A prototype for those Tomix loops?

Of course, these tiny loops of Tomix track may be great fun but they're hardly prototypical. Are they?
A system I've become very interested in is the Slaskie Tramways, in Upper Silesia, Poland. It's a complex network in an old industrial area, largely operated by classic cars, derived from Tatra  PCCs. Here's a great overview. I've been exploring some of the routes in Google Earth and came across this gem.

It's just north of Pogon Akademiki. Route 27 trams terminate there (other routes continue), then run forward to this loop to turn before heading back. Here's a map should anyone be interested.

Another one is nearer Katowice, allowing trams on routes 23 and 37 to turn. It's more scenic than the first example and has a rather neat little station, Szopienice Petla, inside one of the triangles.

Here's a view of the station on Streetview:

And if these aren't prototypes for a Tomix loop, I don't know what is!
