The ending location marker is inside the building and there's no way to get to it. After you go around the 5mph curb and in the manual switching area, if you switch directly toward the objective you'll run into the building causing a de-rail. If you try to switch around the building you'll either run in to a non possible red light or a track that has a stopped train on it. Along with that, I kept getting derailed by NPC trains that where SPAD'ing from spawn. I have no clue how to complete this journey. Any help would be appreciated. The actual name of the journey is "Amtrak Northeast Regional #66 (Boston-Depot)"
