I don't have access to any of the engineering drawings or material properties, so no structural analysis on the entire station can be done. At this point, I'm just noting that there is space at the station for a streetcar line, but the station's bus terminal would require some modifications to enable for proper turning radii and fitting of Flexities. Space is constrained, yes, so the routing I proposed may not work, but those issues can be mitigated through another routing (which may include some expropriation). In terms of structural strengthening, if the line does indeed go over the subway, it might be necessary depending on the route one takes, but there's no way to consider that now when we don't have access to the data necessary to complete the structural analysis.T%he exit route you have chosen is the empty space because it is directly over the subway tracks. That's why it is unused. Are you sure they can actually build anything top of that? It been a while, but I also recall there being a grade change here too which would be a hindrance.
