the IRT Broadway–Seventh Avenue Line and 42nd Street Shuttle. Service changes Trains to Grand Central run 20 hours a day. , plans called for 24 trains per hour to run to Grand Central during peak morning hours, with an estimated 162,000 passenger trips to and from Grand Central on an average weekday. Bilevel rail cars, such as the LIRR's DM30AC and C3 fleet, cannot serve Grand Central because of low height clearances in the 63rd Street Tunnel. When East Side Access was being developed, the project was planned to increase passenger loads on the already overcrowded IRT Lexington Avenue Line and on surface bus routes on the East Side. At the same time, the project was expected to reduce the load on rush-hour E train service between Pennsylvania Station and Midtown East and 7 train service across the East River. Timetable overhaul In anticipation of the completion of East Side Access and related projects, in 2022, the MTA overhauled LIRR timetables for the first time in more than 30 years. On June 2, 2022, the MTA released draft timetables that LIRR president Catherine Rinaldi pronounced "revolutionary", saying, "In one stroke, we are increasing service by 40%." The public was invited to comment on the proposed changes at a virtual public meeting on July 13, 2022; after hundreds of people registered to speak, two more such meetings were added. These meetings notwithstanding, MTA officials said in December that the late-June draft would be implemented when Grand Central Madison opened for full service. The revised timetables proposed a substantial increase in reverse-peak and off-peak service on most branches. This included half-hourly off-peak service on the Main Line to and from Ronkonkoma (increased from hourly) and hourly off-peak service on the West Hempstead Branch (increased from bihourly). Additionally, due to the simultaneous completion of the Main Line Third Track project, reverse-peak service gaps of over 90 minutes along the Main Line were eliminated. Additionally, most branches received service to both Manhattan terminals, with a considerable increase in the total number of trains to and from Manhattan during peak hours. The inconsistent service patterns of most branches were also restructured into simpler patterns with western zones (closer to New York City) and eastern zones (away from New York City). The draft timetables called for more evenly spaced trains. The timetables were also designed to accommodate repairs to the East River Tunnels to Penn Station
