jwb,
your French track ist listed under "Oberbau Hs" in the link i gave you in my previous post.
To German Toy Trains H0 Scale:
This is one of the better rails.
This is the 95% reality. Note Grand Canyon type frog.
App. 95% of the, so called, Modellbahner have such kind of trackwork on their layouts. A puzzled collection of old and older toytrain tracks.
What you see in magazines is the rest of 5%; only the tiny peak of an icemountain.
Even newest products like this double slip are cruel.
Note the "plastic desert" between outer (metal)rails. Only high speed trains and locos have the chance to pass without stalling.
Nearly all of this toy train switches have frogs where the wheels rode on their flanges onto the frog bottom. If depth of frog and depth of flanges are just the same o.k. But this is never the case. The wheels seen on the first photo have the depth of 1.6mm (!)
1.6mm flanges were still in the 1970's the rule .
Meanwhile the flanges were reduced with the result of, that every wheel will fall into the frog when a car or loco is passing the switch.
Be glad you have the NMRA in the US with her standards an RPs which is the guarantee for smooth riding of the H0 US rolling stock. This is possible because the manufacturers of model RR made their stuff according to the NMRA standards.
Of course here in Germany we have the NEM
Yes, they made "Vorschriften" and "Normen", but most of the manufacturers of German model RR stuff simply ignore them.
Here is a link to a German model RR magazine which made public acess to the NEM Normen:

Compare:
NEM 310 with NMRA S-4.2
Theoretical it seemed to be acceptable, but ...
... have a closer look to the NEM340 !
The NEM340 is not a standard, it is only a describing of the situation of "as is" at the date when it was written (note date!). Every time Märklin can change their measures without notification to the NEM or anybody.
And Märklin is not the only manufacturer.
As a reaction switches and frogs are made very tolerable to meet the biggest part of the Modellbahners. Remember track and switches are often very old and as a further result models of rolling stock, even the newest and finest have had to constructed to negotiate very sharp and narrow radius which culminated often into a toy like apperance.
As a final result you got at least camoflaged toy trains.
And that make German model railroading so complicated and toy like.
There a 2 manufacturers of track systems in Germany who made tracks which accept NMRA RP25/110 wheels and NEM310 wheels:
Tillig-Elite, direct link to their Elite track:
<!-- m --><a class="postlink" href="http://www.tillig.com/Elite_Gleissysteme.html">http://www.tillig.com/Elite_Gleissysteme.html</a><!-- m -->
Gleise : tracks
Flexgleise : flexible tracks
Weichen / Kreuzungen : switches / crossings and double slips
And Weinert, a small but exclusive manufacturer:

<!-- m --><a class="postlink" href="http://www.weinert-modellbau.de/download">http://www.weinert-modellbau.de/download</a><!-- m --> => Mein Gleis pdf.
These both are in my opinion the best available tracks for German prototype RR and real model trackwork.
Roco Line is not bad ,but still has frogs made for flangetip running and causing
The rest is simply a toy.
