that were the wrong size; failing to cooperate with other transit agencies in Sunnyside Yard; and making infeasible construction-timeline estimates. In a bid to lower costs and reduce delays, in September 2018, the LIRR hired Arthur R. Troup, who previously held senior positions with Atlanta's and Washington, D.C.'s rapid transit systems, to lead the East Side Access project. Incidents and accidents Several major accidents occurred during construction, and East Side Access has been cited for numerous safety violations. In late 2011, a construction worker died after a tunnel collapsed. In October 2014, a contractor who was digging wells on the Queens side accidentally punctured the subway tunnel underneath, grazing an F train with passengers inside. Associated projects Arch Street Yard and Shop Facility The Arch Street Yard and Shop is in Long Island City, near the Hunterspoint Avenue station. The yard itself has been in use since at least 1910. The Arch Street Facility includes tracks that were built on the right-of-way of the LIRR's former North Shore Branch. Although the branch formerly extended west to what is now the Gantry Plaza State Park on the East River shoreline, the Arch Street Facility's storage tracks only extend as far as 11th Street, several blocks away from the river. The LIRR planned a maintenance facility in the yard as part of the East Side Access project. The building was completed in either December 2004 or June 2005. The $80.4 million facility was built using a mix of federal and non-federal funds. The LIRR had built the Arch Street Facility in advance so it could test its then-new M7 cars. When the MTA planned the facility in 2002, it had anticipated that East Side Access would open in 2011 and that the Arch Street Shop could be used to maintain the LIRR fleet. It was thought that the Hillside Facility would not be able to maintain the expanded LIRR fleet on its own. However, after the East Side Access project was repeatedly delayed, the Arch Street Facility was ultimately leased and licensed for other uses. Just south of the Arch Street Yard, the Montauk Cutoff connected the Main Line to the Montauk Branch until it was decommissioned in 2015. As part of East Side Access, a portion of the cutoff was demolished to make room for the Midday Storage Yard. New Sunnyside station A new LIRR train station in Sunnyside on the
