Having grown up in NYC and being a user of its subway for all my life, I was
wondering about some of the differences between it and the London tube. Both
systems are some of the first ever constructed, with London being the
oldest, IIRC. I have traveled the London tube, and found it superior in some
ways to NYC, even with its problems, and not as good in others. (But then
again, what system doesn't have some degree of issues to contend with?)

As a history buff, I am curious as to how the London system started, and
where the first line or lines were. NYC's system started as a private
enterprise, the Interborough Rapid Transit system, and the only line it ran
was from City Hall in Lower Manhattan up to 116th Street, in what is now
Spanish Harlem. Back then, (in 1904) this was the upper limit of urban NYC,
at the end of Central Park.
