As such, they were forced to offset the car bodies about half a foot for clearance.ExCon90 wrote:Some years ago, Milan introduced off-center unidirectional cars with more overhang on the right side than on the left because of limited clearance between tracks in the street. To achieve a wider body they had to put all the increased width on the right side of the vehicle (presumably they counterweighted the cars to compensate for imbalance). No way to do that with bidirectional cars.And this wouldn't be necessary on North American or Australian systems because of wider track centres. Even Prague has never had trams like this as far as I can tell.
Were such a line to be reconstructed now, either the equipment would be narrower, on-street parking would be eliminated, or the line would be single-tracked or made gauntlet at those points. It'd only be a problem in existing systems, and would once again remove the need for unidirectional equipment.
