to function as a high-frequency shuttle service to Atlantic Terminal, and most trains from Long Island will proceed to either Long Island City station, Penn Station, or Grand Central via the Main Line. The first phase of the project, including the new platform, was completed in 2021 at a cost of $380 million. Another project will add train storage capacity at two LIRR stations. A siding near Massapequa station on the Babylon Branch will be used to store trains that originate or terminate at the station, enabling more peak-hour service to and from Penn Station/Grand Central. It was originally planned for completion in April 2019, though was delayed until June 2021. The MTA is also extending Track 2 on the Port Washington Branch, which ends as a pocket track east of Great Neck station, eastward by so it can store two trainsets. Additionally, a new bridge was built at Colonial Road near the station; it opened in May 2016 and replaced a 114-year-old span. The construction of the pocket track was originally scheduled for completion in December 2018 at a total cost of $45.2 million. However, the completion date was pushed back several times; , a tentative completion date of August 2022 was annnounced, though construction is still underway as of November 2022 and is now expected to be complete by the end of the month. Finally, the MTA planned to expand two yards. The MTA expanded the rail yard along the Main Line/Ronkonkoma Branch next to Ronkonkoma station, increasing the number of tracks in the yard from 12 to 23. The project was budgeted for $128 million. Construction started in July 2017 and the expanded yard went into service in late 2020. Additionally, the Port Washington Yard, next to Port Washington station on the Port Washington Branch, was planned to be expanded to store two more ten-car trains. , construction was scheduled to begin in late 2020 or early 2021 at a cost of $500,000. However, this project met significant community opposition, primarily because of proposed reduction of parking spaces near the station. , the MTA has not come to an agreement with the Town of North Hempstead, resulting in the project being postponed indefinitely. New railcars The LIRR also plans to purchase new railcars—up to 160 M9 cars—to handle the increased passenger traffic expected when East Side Access opens. They are being paid for with federal grant money
