I have an unlimited interrail pass for next 2 months. I was wondering how can I use it with the 9 euro ticket if I want to travel from Paris to cologne? I would prefer to not use my interrail journey in Germany since I only have one left.
When I search for Paris - Cologne it shows trains with no connections. Is it possible to change train at France-Germany border and take a regional train to cologne?
So I think I can pay 25 euros from Paris to Hergenrath for seat reservation and then buy 7.5 euros ticket from Hergenrath to Aachen HBF and then its 9 euro ticket as long as I stick to regional train. Does this make sense?
The 9 Euro Ticket won’t be valid from Hergenrath to Germany. It’s only usable within Germany, e.g. from the border point to any other point in between. There is a technical border point on this route, that is
„Aachen Süd(Gr)“.
You might be able to travel to this border point with Interrail and continue with the 9€ ticket without buying any other ticket. However, I’m not 100% confident that the 9€ ticket is even valid on this train operated by SNCB. You might have to check this first.
On Aachen - Cologne you shouldn’t have any issue travelling with a local train. From what I see you’d have to leave the TGV in Brussels and continue with Belgian Railway from there to Hergenrath.
I know. But for every rail that crosses a border, there is a defined border point. There even is a long Wikipedia article about these „Grenztarifpunkte“ which translates to „border fare point“:
However, it might not be possible to purchase a ticket from Aachen Süd (Gr) to Aachen anyway. So the more likely option is to just get a ticket between Hergenrath and Aachen for €4.50
