The left panel of Figure A1 compares the GDPtrend of Koblenz to its synthetic counterpart. Koblenz as a potential stop on the placebo HSR lineroughly corresponds to Montabaur in that it is located in Rhineland-Palatinate and is a comparabledistance from Cologne and Frankfurt. Notably, Koblenz is located about 25km to the west of Montabaur,so that positive – or negative – spillovers from the Montabaur station could exist, in principle.The two trended lines follow a relatively similar long-run trend. There is no or at least no persistentdivergence in the trends after the placebo HSR opened. Similarly, there is no evident break in therelative trends in the number of in-commuters (right panel).
