TARGET 081210

A Diamond Below

Unbeknownst to the thousands of people who walk and drive along the busy streets of downtown Brooklyn every day, they are treading on a 170 year old secret. At 17 feet high, 21 feet wide and 1,611 feet long, it is a big secret indeed, and one filled with greed, murder and corruption.

Down the hole
Not long ago, a young engineering student got the chance to go down a manhole in the middle of Atlantic Avenue to find a mystery he had been seeking. What he found was truly unbelievable.
Walt Whitman once wrote a column for the Brooklyn Standard called “Brooklyniana.” In an 1861 column, “A passage of Solemnity and Darkness,” Whitman wrote of “the old tunnel, that used to lie there underground, a passage of Acheron like solmnity and darkness, now all closed and filled up, and soon to be utterly forgotten, with all its reminiscences…” Walt, as it turns out, was only half right. He was right that the tunnel, which he described as “dark as the grave, cold, damp and silent” was, for a time, utterly forgotten. Where Whitman was wrong was in describing the tunnel as “filled up.” For although he didn’t know it, The Atlantic Ave. tunnel remained there just below his feet all along waiting “cold, damp and silent.”

In 1844 Brooklynites had a problem. They kept getting run over. Cornelius Vanderbilt, then director of the Long Island Railroad, ran a train right through downtown Brooklyn on busy Atlantic Avenue. Without air brakes it took a train up to 8 city blocks to come to a stop, not that the trains stopped for people anyway. But while Vanderbilt cared little about the fate of a few poor Brooklynites he did care about keeping his train on schedule. To avoid this human nuisance, it was decided a tunnel ought to be dug. It was to be the first underground, or “grade-separated” transportation system. The world’s very first subway.

Using the cut and cover method, the street was dug up for roughly 12 blocks, a wooden frame was built, a barrel vaulted brick roof put in, and the street relayed, all in the astonishingly short time of seven months. The work was done almost entirely by Irish immigrants. When the Irish workers were told by a British contractor they would have to miss church and work on Sundays, according to an 1844 Brooklyn Eagle article, an Irishman pulled a gun, shot the Brit, and the group buried him behind the wall of the tunnel-where presumably his body still resides today.

By the end of the 1850’s the tunnel had lost much of its use. Vanderbilt had left the LIRR to pursue riches by running steamships to California, and the tunnel fell into disuse. Political maneuvering led to trains in Brooklyn being declared a nuisance. The tunnel was to be shut down, filled in and closed up. The 130,000 dollar contract to do so was awarded to a shady operator named Electus Litchfield. Litchfield, however, had other plans. Rather then filling in the tunnel, he filled in the ends of tunnel, capped up the holes to the street, and had some cronies sign a document that the tunnel had been filled in completely. Litchfield made off with a good deal of money and everyone except Litchfield and his buddies thought the tunnel was gone forever.

Skip ahead a little more than 100 years to 1979. Bob Diamond, a 19 year old Brooklyn engineering student, sits in his kitchen doing differential equations and listening to the radio. “The Cosgrove report”, a book by G. J. A. O’Toole about Lincoln’s assassination, was being discussed and included an offhand mention in the book of the lost journal pages of John Wilkes Booth. According to O’Toole, the announcer says, the pages might be in a long forgotten tunnel running under Atlantic Ave. Of course the whole thing sounded absurd but the young Diamond couldn’t help but find his interest piqued.

Diamond called into the show but the announcer had no more information. Diamond managed to get in touch with O’Toole but the dismissive author knew nothing else, he had just heard a rumor of the tunnel. He told Diamond to “go find the tunnel yourself.” The 19 year old Diamond decided to do just that, transforming himself into a kind of Brooklyn Indiana Jones. “I scoured through all the newspapers printed in Brooklyn during the 19th and early 20 centuries. I found an article in the Brooklyn Eagle, 7/23/11, a full page about the tunnel which told about a set of plans in the borough president’s office” Diamond recalls. When he got to the office they told him that there were no such plans. Diamond asked if he could look through a locked box of old unmarked papers. After jimmying the lock, and sifting through ancient deeds and Dutch histories, there, rolled up in the box were the plans for a 1,611 foot long tunnel running under Atlantic Ave in Brooklyn. On the plans was a little blue circle, representing a manhole, and quite possibly, an entrance.

In the early morning of 1981, Diamond stood on the corner of Atlantic Ave and Court St, looking down at a small smooth manhole. The manhole looked unlike any others layed down by the city. It had been almost a year since had started his search. With the help of some friends at the department of transportation, Diamond opened the manhole, dreams of the tunnel dancing in his head, but a foot beneath the opening was a solid floor of dirt. It looked like he was wrong. The tunnel had been filled after all. As the DOT guys prepared to leave Diamond decided to make sure. Crawling on his stomach he inched along the crawlspace under the street until he came to a place where the dirt met the ceiling. In a last ditch effort he began digging through the dirt with his hands. A few inches beneath the dirt his fingernails scraped on a poorly constructed brick wall. It looked like it had been built in a hurry. Using a large metal pole Diamond smashed through the brick wall, sending a cascade of bricks into an empty space. Diamond put his head through the hole. On the other side was a 15 foot drop into a dark space large enough to hold a freight train. Diamond had found his tunnel.

Every ten years or so an article would be written in a local paper about the tunnel, musing that it might still exist. River pirates, bootleggers, mountains of treasure, Jon Wilkes Booth’s lost diary, and even “Persian Vampires” (in H.P. Lovecraft’s “Horror At Red Hook”) were said to live within the mythical tunnel. While Diamond found no pirates or vampires in the tunnel (yet), the mystery is not over. The tunnel is blocked in the middle by a large wall, leaving roughly six blocks of the tunnel, as of yet, unexplored. Diamond believes there is a good chance that a locomotive originally built by British locomotive pioneer Robert Stephenson may lay in that section of tunnel. Booth’s diary may be there after all. Diamond hopes to gain access to the final section of the tunnel sometime in 2009, and “What’s behind the Wall” a documentary about Diamond’s quest, is currently in production.

Today you can still occasionally tour the tunnel. You access the tunnel by filing down one by one through a manhole cover in the middle of busy Atlantic Avenue. Bob Diamond, re-discoverer of the tunnel in 1980, is still giving the tours. Diamond is a wellspring of fantastic stories about the origin of the tunnel and how he came to find it. The tunnel is truly a marvel, and walking through the 170 year old underground passage is an experience like nothing else in New York; it is still, as Whitman said “a passage of Acheron like solmnity and darkness…dark as the grave, cold, damp and silent.”
