That, I want to see. Not sure where I read it (might have been The Interurban Era or The Time of the Trolley) about the Boston-to-New York trip, and the New York-to-Chicago trip albeit with the 20 mile or so gap in upstate New York. I'd be fascinated to see the timing of such a potential (and obviously physically demanding) route.I'll try to find where the article is but at one time I read that you can go from Maine to Iowa by Interurban which of course meant a lot of changes. SEPTA didn't close the Allentown to Philadelphia until late 50s early 60s,
Picky point, but SEPTA didn't acquire PTC, Philadelphia's transit system, until 1968, and didn't acquire Red Arrow until 1970. By then, Lehigh Valley Transit was kaput: the Liberty Bell Allentown/Philadelphia service ended in 1951.
