Though crossing through the Pennsylvania broad gauge region was impossible, east of the Hudson, just about everything was connected and all standard gauge. Bay state cars made the trip from Boston to the Bronx several times. Of course we know that they then encountered the conduit which for them was impassable. Excursions in the northerly and westerly directions, from Boston were common and freight ran regularly from Boston to distant points via Springfield. The only gap in the apparently
continuous system was the ferry from Portsmouth NH to Kittery, Maine. From there all was connected all the way to
Fairfield. In Maine and central Massachusetts, there was a fair amount of steam road interchange so, one had to
consider wheel treads. A great part of the Southern New England network belonged to the New Haven RR, including the Connecticut Co., R.I. Co. and lines extending from around Milford MA to Hoosick falls NY (rather briefly).
Many New England lines were of the same or higher standard than the average Midwestern line but, there were also
many light feeder lines as, the network was much denser than elsewhere (well over 2000 miles in Mass. alone,
the only state to have a greater mileage of trolley than steam (I always wondered if this was also true of RI though)
The AERA considered most of these lines to be interurbans but, Hilton didn't. I suspect he thought his book was big enough
and he didn't know as much about the east anyway.
