I have seen photos of the Newark light rail and they only show off-street track. This makes we wonder if high platforms are possible in all locations. Low floor LRVs were originally developed to acheive level boarding mainly on street based systems where at least some stops cannot have high level platforms. Has Newark been able to avoid the problem that low floor rolling stock was designed to solve? Have high platforms been considered for Newark.
Just remember there are unavoibale trade-offs of having floors lower than the wheel tops. Must North American ones seem to have pivoting bogies and part high floor. There are some 100% low floor designs but most of them have fixed bogies, and all have wheel boxes where the bogies are. This means that low floor rolling stock is really only suitable for applications where the constraints on providing high platforms outweighs the trade-offs of having low floors. If high platforms are possible in all locations, then one can have level boarding without the trade-offs of low floors.
