1 seat ride from raritan to hicksville, I can't complain. Your map finally brings service to St. John's University in Queens (where I go to school) and it gets well needed extra service for Jamaica and LGA.
If you want to talk about "fantasy" then buy the book I co-authored and check out the chapter on the New York & Portchester. It was supposed to be a four-track, third-rail electric railroad from the Bronx to Port Chester, via the Sound Shore. Chartered in 1901, the New Haven took notice, squashed it, acquired the NYW&B, merged the two, and built the NYW&B instead. Imagine a true-rapid transit line from the Bronx into Westchester?
The Yonkers/Getty Square Branch was built like the typical steam powered El's of the 1880s... and very easily could have been tied into the IRT after they took over the Put's Harlem River Swingbridge in 1916... In fact, the line was operated with tank engines and el coaches until electrified by NYC in 1926.
When the NYW&B was abandoned and awaiting its fate, there was a proposal to run express service from White Plains to 180th Street on the center tracks, while Subway service operated on the outside tracks to the Bronx/County line. Of course, Westchester couldn't get its act together, so all we have left is a stub of the NYWB/No. 5.
Buy the book. It's good readin'.
