True, although I think milomilo was comparing high floor LRT with low floor LRT, all else being equal.
I would agree with him. I think low floor LRT is an inferior choice in almost all respects except integration of the station with the street environment in a dense, enclosed urban area.
If I'm not mistaken, low floor LRT compromises internal layout, capacity and passenger movement since the trucks (bogies) take up a lot of space that would normally just be under the floor. This leads to a narrow gangway that people can't move around in, so they just stand in various clumps rather than spreading around the car. I would need confirmation on this, but I think the cars might be more expensive and trickier to maintain, since all the electromechanical components have to be on the roof, or more compactly housed under the floor. Low floor LRVs and low floor platforms are certainly less useful for people in wheelchairs, since you don't actually have level boarding and there are the aforementioned circulation problems.
If agencies must use low floor platforms for legacy purposes, like the TTC streetcar, I don't know why they insist on buying 100% low floor LRVs. Partially low floor LRVs are a dime-a-dozen and their internal circulation isn't any worse. It's not like someone with a wheelchair can make it past the narrow gangway between the trucks anyway.
I really don't understand why 100% grade-separated systems with no intention of ever running LRTs on the streets insist on low floor (e.g. Ottawa).
