Yes, the kinematic envelope can determine the position of the bogies and, when they swing, the width of aisle, or indeed whether it is possible to have a trench aisle at all at the ends of the tram. Trams with swivelling bogies running on metre-gauge track do have an issue with having a low floor at the ends of the tram if the curve radius and clearance are too tight, so they have a high floor over the end bogies. Such is the case with the FCB trams. Conversely, the metre-gauge trams in Helsinki are presumably in a better situation and the Škoda trams there have a low floor from end to end.

But the body will overhang more on curves. Presumably Prague has a more
generous track spacing than Melbourne.
