On February 26, 1870, New York’s elite gathered in the basement of Devlin’s clothing store in Tribeca, venturing into a hidden, unsanctioned tunnel that City Hall knew nothing about.
The evening was orchestrated by Alfred Ely Beach, a New York inventor with a flair for showmanship. He created the extravagant “Under Broadway Reception” not just to showcase his secret pneumatic tunnel but to enchant the influential figures of the city.
“Beach pulled out all the stops to impress attendees,” writes Matthew Algeo in “New York’s Secret Subway: The Underground Genius of Alfred Beach and the Origins of Mass Transit” (Island Press, now available). “He adorned the waiting area with a grand piano, chandeliers, and a goldfish-filled water fountain.” The subway car featured luxurious upholstery and was aglow with zirconia lights.
Beach’s opulent launch was not merely a display of ego; he intended to translate this spectacle into legislative support, using the guests’ enthusiasm to press lawmakers. Attendees were encouraged to sign petitions “calling on legislators to allow Beach to expand the line, and thousands complied,” Algeo shared with the Post in an exclusive interview.
Long before the petition effort, Beach had duped officials into thinking he was constructing a simple mail tube. Instead, he excavated an eight-foot-wide, approximately 300-foot tunnel directly underneath Broadway. He held the belief that showcasing a safe, operational line would be more persuasive than asking for permission. “It served to demonstrate the feasibility of his design — a proof of concept,” Algeo explained.
However, powerful business and political factions were opposed to a subway running beneath Broadway. The proprietors of horse-drawn streetcars and stagecoaches bribed political figures like Boss Tweed to hinder Beach’s ambitions.
Beach’s secrecy also functioned as a form of product design. He sought to create an experience so superior that public opinion would eliminate resistance. The pneumatic subway he presented that February night in 1870 was fresh, quiet, hygienic, and comfortable — in stark contrast to the sluggish, dirty omnibuses and streetcars. The strategy was straightforward: let New Yorkers experience it, and their excitement would carry the message.
In a city eager for mechanical solutions, Beach believed he had constructed the answer to Manhattan’s traffic woes. “It was a solution he was so passionate about that he risked his reputation, his fortune, and even the possibility of prison for its realization,” Algeo noted.
Had the tunnel collapsed, his legacy would have been vastly different.
“It evokes comparisons to the Titan submersible that imploded in 2023 while heading toward the Titanic wreck site,” Algeo remarked to the Post. “The Titan operators took significant risks that ended tragically. Beach’s subway was a remarkable engineering feat, but it too carried considerable risk in his approach.”
The venture raised eyebrows, especially when officials noted that the street above the excavation was sinking by approximately nine inches. Charles Guidet, a contractor who had recently resurfaced Broadway, observed with alarm that “the street appeared to be lowering near City Hall,” Algeo reported. “He suspected the unusual happenings beneath the Devlin building were to blame.”
The mayor acknowledged similar observations and directed Guidet to look into the matter. However, Beach denied him access, asserting that the mayor had “no authority to interfere.”
Ultimately, Beach’s project never advanced beyond a proof of concept. The opulent tunnel beneath Broadway remained a one-block showcase. His petitions and media coverage could not surmount the coalition of streetcar interests and City Hall, stalling the initiative before it could reach further uptown.
Tweed’s opposition may have curtailed Beach’s aspirations, but the Boss himself faced consequences. His attempts to revoke Beach’s charter proved futile, and he was unable to obstruct rival pursuits like Charles T. Harvey’s elevated train line.
In the end, New York did not gain an underground transit system from Beach; instead, it glimpsed a vision of what was on the horizon. Three decades later, the city finally commenced construction of a true subway, with the first line launching on October 27, 1904. Lower Broadway did not witness a subway until 1918.
This narrative feels strikingly familiar. Today, large infrastructure projects still navigate the same challenges: complex permitting processes, NIMBY opposition, and legislative bottlenecks that can stifle a viable prototype just as effectively as a flawed plan. Beach demonstrated that physics was not the barrier; politics was — and often continues to be. From contentious congestion pricing to excessively costly megaprojects, the real choke points lie less with the tunneling machinery and more with the schedules of committees.
Algeo draws parallels between Beach’s pneumatic system and Elon Musk’s Hyperloop. Both capitalize on the allure of sealed tubes, streamlined vehicles, and sparkling stations that promise speed and cleanliness. The distinction lies in the technical and practical aspects; the Hyperloop relies on far more intricate systems — including vacuum maintenance and magnetic propulsion — and its recent demonstrations have struggled to succeed.
The author humorously stated, “Beach successfully built a fully operational version of his concept, whereas Musk has yet to accomplish that.”
