In 1870 Alfred Ely Beach built a pneumatic subway beneath Broadway in New York City, constructed largely in secret.

the verdict
INSUFFICIENT LEANING
Recorded sources
2 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that in 1870 Alfred Ely Beach built a pneumatic subway beneath Broadway in New York City, constructed largely in secret?

Unclear. Two reference items confirm that Alfred Ely Beach built and opened a short pneumatic subway under Broadway in 1870, but neither addresses whether it was constructed largely in secret, so the evidence covers only part of the claim.
