Tunnel deaths

193 lives were lost during construction, leading to the nickname "The Bloody Pit." The Hoosac Tunnel was the first commercial use of nitroglycerin in the United States. Some lives were lost due to the unstable nature of nitroglycerin, but many more were lost to the even more unstable black powder, which was used before nitroglycerin was introduced. A number of others were killed by the horrendous Central Shaft accident.

The accident was one of the most fatal; it occurred while digging the tunnel's 1,028-foot (313 m) vertical exhaust shaft, called 'Central Shaft.' On October 17, 1867, a lighted candle in the hoist

 fumes which had leaked from a 'Gasometer' lamp, triggering an explosion. The hoist caught fire and collapsed into the shaft. Four men near the top of the shaft escaped, but thirteen men working 538 feet (164 m) below were trapped, killed by falling flaming naphtha and pieces of iron. The pumps were also destroyed, and the shaft began to fill with water. A worker named Mallory was lowered into the shaft by rope the next day; he was overcome by fumes and reported no survivors.

Workers assumed that nobody at the bottom survived, so no further rescue attempts were made. However, when the first workers got to the bottom several months later, they found that workers had, indeed, survived and had built a makeshift raft, but had died, suffocated by the fire.

Construction technology

The tunnel construction project required excavation

Digging the Central Shaft also allowed workers to open 2 additional faces to excavate: once the shaft was complete in 1870 workers dug outwards from the center to meet the tunnels being dug from the east and west portals. Engineers built a 1,000-foot (305 m) elevator

 to hoist the excavated rock from the Central Shaft.

One of the many engineering challenges posed by the project was getting the proper alignment between the four tunnel segments that were being dug: the east and west portal tunnels, and the two tunnels dug outward from the central shaft. Engineers cleared a path through the forest over the mountain, and strung a straight line from the east to west portals, through "sighting posts" on the east and west peaks of Hoosac Mountain.

 verified the line ran true between the posts, and steel bolts were installed at fixed intervals along the line.

On December 12, 1872 workers opened the east portal tunnel to the Central Shaft-dug tunnel, which were aligned within nine sixteenths of an inch (1.4 cm), a tremendous engineering achievement at that time. On November 27, 1873 the remainder of the tunnel was opened to the west portal tunnel.

Lewis Cuyler of the Hoosac Tunnel Museum Society described the project as the 'fountain-head of modern tunnel technology.'
