@retiolus I'm late, but for next time

- Dutch transit providers collaborate to provide a central source of info: 9292.nl

- The biggest rail operator also combines transport modes nowadays and can give more detailed info if your trip has a train component where you care about these details: ns.nl

- Europe-wide, I've been pretty happy with german Bahn. Less detailed outside of DE, but avoids needing separate solutions for each country: bahn.de
