Watch MTA Sandhogs Dynamite Their Way to Grand Central

April 10, 2013 | Andy Cush

The MTA released this video to commemorate the end of blasting in the decades-long East Side Access project, which will eventually extend Long Island Railroad Service into Penn Station. After about 40 seconds of montage peppered with stats about the massive tunnel-clearing undertaking–2,424 explosions, 200 blast holes drilled–you’re treated to footage of a glorious dynamite explosion. And if you’re patient enough to sit through until the end of the three-minute video, you’ll see the whole thing again in beautiful slow motion.
