I would have felt a tad better if such tool had originated in Switzerland rather than France.
The railway system in Switzerland is far, far more reliable, far more central to the Swiss economy and proportionally (Switzerland is smaller than France) services much more of the country in terms of both geographical reach and service frequency.
But ... credit where credit is due, kudos indeed to the Frenchies for building and open sourcing something like this, I would love to see a video of it in use.
[EDIT]: I skimmed through the documentation, and I haven't found anything pertaining to monte carlo simulation of a complex railway system subject to external perturbations, as in: throw a bunch of unexpected events (accidents, breakdowns, blockages, late trains from a neighboring country entering the system, etc...) and see how well the whole network's efficiency holds under such disturbances.
Maybe I am misunderstanding the purpose of the system.
[EDIT 2]: OK, found something. Such a "how well does the network do under perturbation" is not part of the feature set yet but seemed to be in the cards. From [1], in section "Operations studies / Planned features include", I read: "automated timetable robustness assessment using stochastic simulation".

- arbfay 2y agoSeriously... This is like not trusting the cooking book of an American chef because America has poor food quality. Or British chef in Britain. Individuals' talents are not bound by their countries' failures and successes. And comparatively the French train network is excellent, and faster than the Swiss network. No, I'm not French at all.
- ur-whale 2y ago> And comparatively the French train network is excellent I don't think we're talking about the same country here. Are you a regular user ? "Comparatively" ? Sure, if you compare it to the US train network or to Uganda's ... "comparatively", you can always find something to compare to that makes you look excellent.

The French railway system suffers from a few faults (like the fact that it's Paris first, or not enough capacity on some routes, especially around popular times like Friday afternoon), but is otherwise extremely good. There's very fast coverage between all big cities aligned to Paris (so Lille - Lyon - Marseille is super fast, but mostly because they are destinations linked to Paris); Marseille - Bordeaux is slow because it isn't aligned to Paris, and has to pass through bad terrain in the middle of nowhere). In terms of coverage of % of the population with regional or high speed rail, or hell, low cost low or high speed rail, it's among the best in the world. It's only serious challengers are Spain, Italy, Japan, China.
- georgesimon 2y agoPresuming there's a reason you excluded Germany, would you make a comparison with that system?
- sofixa 2y agoThere's very little high speed rail in Germany, which means that longer trips are too slow to be useful. That being said, there's very good regional and decently fast coverage. Delays are a problem due to postponed infrastructure investments though.
- georgesimon 2y agoThanks, that's my impression too. I wouldn't say Spain is much better, but my experience is limited.

- PetitPrince 2y agoThere's a similar-but-different tool developed by SBB CFF FFS[1], it's even mentioned in the documentation of OSRD[2]. Both tools operate at different scope, if we're to believe the documentation (OSRD is micro, Netzgrafik is macro).

- p_l 2y agoThere are also similar, commercial closed source systems from SISCOG[1][2] [1] https://www.siscog.pt/en-gb/ https://www.siscog.pt/en-gb/ [2] https://www.siscog.pt/en-gb/products/#railnode https://www.siscog.pt/en-gb/products/#railnode
- PetitPrince 2y agoOP wanted something developed by the Swiss railways company though (but SISCOG seems to be used by the Dannish, Finnish, Norwegian, Canadian and Catalonian railways).
- javilovesmambo 2y agoYou can put it on a different way, the Swiss have no use case for such a software since everything is running fine. On the other hand, the French need the solution and are more experienced dealing with railway traffic problems.
