Perhaps another city can be build i bit further than the terminal with a terminus station where the Intercity Direct can stop. An example of St. Pancras, but without Ebsfleet, Ashford and Stratford station. Than you can ask
Michiel from the Simvliet layout to build the same, but from another line. The it looks like the layouts are the combined, but without a direct service from Rijndam to Simvliet.
