@jon I ran into another #CrossBorderRail ticketing anomaly yesterday when trying to book train tickets for my 60+ father. DB Navigator gives a €76,99 offer for a ticket Maastricht-Berlin. Book the same connection from Herzogenrath – dropping the 41 minute cross-border Drielandentrein but with the same 5:28 hour ICE –and the price is less than half: €37,99.
The Maastricht-Herzogenrath train costs €10,80 with Dutch OV-Chipkaart, meaning DB essentially overcharges €28,20 here...
