I did not realize the proposed area already had a passing siding. That is a problem that an island platform will not solve it. Look at Wesmont. It is an island platform, but still required two elevators to the overhead bridge. If you have an overhead bridge you definitely need the elevators given that the bridge needs to have clearance for double stack trains. In addition to that Wesmont has clearance for wires if the Bergen line ever gets electrification. Even without that extra height for wires it still seems pretty high to me for ramps. With a pedestrian tunnel under the tracks the required clearance is much less, so ramps might work. But tunnels are expensive -- that is why all new construction has involved overpasses.
I am unsure why but I am pretty certain that pedestrians crossing at grade are not being built any more (Teterboro could have used one given that the station is on the opposite side of the residential neighbourhood). NJT is even trying to close the existing one at Ho-Ho-Kus and would gladly eliminate the one at Hawthorne if there was a cheap way to do so. Dover benefits from the existing street crossing as does Plauderville. Is there a street crossing close to the proposed Woodbury platform? No. In fact that is one of the reasons why the double track is there -- there are no crossing. Also note how the double track begins after Harriman station -- otherwise the station will need two platforms and an ADA compliant way to connect them. Additionally note how the proposed future addition of more passing sidings on the line are away from any of the stations -- in order to avoid the cost of modifying the stations which triggers ADA and the need for elevators.
