FAIRFIELD COUNTY, Conn. -- Metro-North has restored all train service to and from Grand Central Terminal after the explosion Wednesday morning in Harlem .
Service had been suspended after the explosion collapsed a building right next to Metro-North tracks running above Park Avenue in Manhattan. Limited service had been restored to the New Haven Line and the Harlem Line earlier Wednesday afternoon, and all service was restored by 5 p.m. to the Hudson Line after additional tracks reopened.
Metro-North engineers have verified the integrity of the Park Avenue elevated structure, and debris has been cleared from all four tracks. The tracks were inspected and approved for operations by Metro-North and the New York City Fire Department.
Also, the National Transportation Safety Board has launched a go-team to investigate a gas explosion and subsequent fire in New York City, according to a release.
Pipeline Investigator Ravi Charter is leading the team as investigator-in-charge. Board member Robert L. Sumwalt is accompanying the team and will serve as the principal spokesman during the on-scene phase of the investigation.
Trains will run at reduced speeds through the collapse zone to protect nearby employees and reduce vibrations on the tracks as rescue and recovery work continues, Metro-North said.
This will result in some delays and crowding through rush hour.
