I am actually disappointed on how easy the achievements for Horseshoe curve are. For a route that is lengthy you would think the two loco achievements would be 100+ miles. I am curious on who in DTG comes up with the achievements.
Correct and for DRA Talent 2 achievement 442km works on SKA Wuppertal Commuter DB BR422 also unlocks for HRR. Making Tracks DB BR 146.2 Riesa-Dresden or any DB BR146.2 layered route from Main Spessart Bahn.
