Vibrations from the explosion knocked groceries off store shelves, obstructed visibility for cars and buses on the street, and sent debris and smoke into the air.
Of the 22 wounded, five are seriously hurt while 15 have suffered more moderate injuries such as cuts and broken bones. Two of them include on-duty FBI agents who were driving through East Harlem at the time, though they are not among those who sustained life-threatening injuries, reported Breaking 911.
Crews are continuing to clear debris from the Metro North line. According to the MTA, "of the four tracks on the Park Avenue viaduct, the two farthest from the explosion site have been restored to service."
Metro North service to Grand Central Station is closed until further notice as "the track configuration does not allow Hudson Line service to operate to Grand Central until more tracks are restored to service."
Because of the changes to service, the MTA is recommending that commuters delay their trips if possible.

De Blasio also added that at least 18 have been injured in the accident and that there are 250 firefighters on scene attempting to put out the five-alarm blaze.
Police Commissioner Bill Bratton told reporters that extinguishing the fire and clearing the scene will be a "long-extended operation."
First responders must first put out the blaze before they will be able to search the building's rubble for survivors.
De Blasio and Bratton were also joined by City Council Speaker Melissa Mark-Viverito, who lives five blocks away from the destroyed building, and said that she was on her way to work when she heard the news of the explosion. She encouraged anyone who believes they may know someone from the building with whom they are unable to get in touch to call the city's 311 line.
