I think a big part of the idea of commuter rail over the Hudson idea is to get Rockland / Orange commuters a one-seat ride into GCT, which compared to Penn, as pointed out on another thread, is under-utilized. Still, isn't the one-seat ride into Manhattan going to be satisfied by ARC? Or is NJ going to eat up all that capacity for its own service expansions?
Assuming commuter rail is built between Suffern and Westchester, then, the questions are: how far east, and where to connect to the east-of-hudson lines?
I think a connection with the Hudson is fraught with complicatons since the road is at river-level. If the new bridge is built with the same approaches and next to the existing TZB, you miss a connection at Tarrytown, unless you build some type of loop, either above land (the visual impact will never pass EIS) or over the river (through the old GM site?). I don't think it works, especially if you continue the line through Westchester.
I don't think a connection with the Harlem is efficient, either, not for NYC commuters. Even with a transfer, staying west of Hudson would probably be quicker. Some have suggested connecting with the old Put, but also as noted elsewhere in this forum, that will never happen for various reasons. I think I've seen it elsewhere as well here - continuing the line down the Thruway is probably the best way for a connection, and a little more populated than the Saw-Mill or Sprain path. I don't think you gain any additional riderhship in Westchester this way, just divert from Harlem and Hudson.
For the line to be worth anything, it needs to run though White Plains, assumedly along a combination of 287 and 119. How do you get the line through downtown White Plains and back to the 287 corridor to get the connection to New Haven? Do you even try or just follow 287? It does seem like there's a need to connect Stamford and WP.
While I prefer commuter rail, the ROW clearance and infrastucture may be too great a hurdle. My guess is they end up with NJT type light rail, especially if they want to get into downtown WP. At least, that's what they'll need east of Hudson, for the non-NYC connection.
Next stop, Willoughby
