Jon WorthToday and tomorrow I’m at #OpenTransport2025 in Wien. Friends and fellow regular rail travellers @moof @bovine3dom @maartje are also here. I’ll post as and when I can!
#OpenTransport2025 Yes ideas can happen in unlikely places. But to the person just scrolling on their phone while pissing at the urinal: that’s grim. Did you wash your phone too? 🤔
Talking to the @transitous people at #OpenTransport2025
One headache: data on international trains that is missing the other side of the border
My EN Dacia Hegyeshalom 🇭🇺 - Sighisoara 🇷🇴 is 1 train but shows as 2 on Transitous
Stefan Lindbohm@jon @transitous This can also be due to the EN actually technically being a coach group (kurswagen), or train that turns into a coach group. Often the carriers on either side don’t even have data on what happens outside their own country.
This is solved in MERITS with a lot of manual links in the form of ”at border station X, train number Y is to be linked with train number Z”
Even with perfect open data in each country (lol), any aggregation of international data needs this integration layer
@stefanlindbohm Yes, but having spoken to the @transitous people here, there are cases where *even with the same train number* the data is snipped at the border. Hungary and Romania are apparently notable for this.
Transitous@jon @stefanlindbohm This is potentially something we can match based on the time and train number, but this would of course be highly heuristic (and therefore not 100%) correct.
It's significantly easier if cross border trains are just in the data twice.

@transitous @jon Doesn’t need to be that crazy. Date and train number (or linked number) is what it’s designed to be matched on.
But I don’t believe a journey planner project should do this at import. It should be a separate project that sorts out the aggregation/integration and outputs clean files that can be used by journey planning projects. I would be happy to advise (not develop - time constrains) such a project. I know others I can ask too (they haven’t spoken publicly on this yet).
@stefanlindbohm I think a conversation between you and @VolkerKrause of @transitous would be useful 😀
@jon @VolkerKrause Happy to do it!
Volker Krause@stefanlindbohm @jon @transitous Great, let's find a time next week maybe if that works for you? I'm still on the road all of this week for another conference.
