back to the 2020–2024 Capital Plan. As part of the 2020—2024 Capital Plan, the Woodhaven Boulevard, Court Square—23rd Street, Steinway Street, Seventh Avenue, Briarwood, Northern Boulevard, and Parsons Boulevard stations will receive elevators to make them compliant with the Americans with Disabilities Act of 1990. Communications-based train control Congestion on the line during peak hours has existed for much of the line's history, and in 2015, the stations along the line had a combined 467,779 entries, making it among the system's busiest. As a result of overcrowding, the MTA is automating the line. Because the line hosts several services, installation of CBTC on the line is more complex than on the IRT Flushing Line and BMT Canarsie Line, which had also received CBTC and which each hosted only one service. The total cost for the entire Queens Boulevard Line is estimated at over $900 million. The automation of the Queens Boulevard Line means that the will be able to run three more trains during peak hours, up from 30 tph, and the local tracks' capacity would also be increased. Phase one equipped the tracks from 50th Street/8th Avenue and 47th–50th Streets–Rockefeller Center to Kew Gardens–Union Turnpike with communications-based train control. The $205.8 million contract for the installment of phase one was awarded in 2015 to Siemens and Thales. In January 2017, L.K. Comstock & Company Inc. was selected to fulfill a $223.3-million contract to upgrade existing signals and install communications, fiber-optic, and CBTC infrastructure for the new signal system. The project also included the conversion of 309 sets of R160 subway cars for CBTC compatibility, which had been increased to 335 sets. The final section of phase one was activated in February 2022. The 2015–2019 Capital Program was revised in April 2018 to fund to the design for the expedited installation of the Queens Boulevard Line east of Kew Gardens–Union Turnpike, the second phase. In December 2021, the MTA Board approved the first of three contracts to install CBTC on the eastern portion of the Queens Boulevard Line. Multiple changes in evening and overnight service are planned to be implemented on March 17, 2023, to accommodate the next phase of work on the QBL East CBTC project. After 9:30 p.m., Queens-bound R trains would terminate at Queens Plaza, and Queens-bound E and F trains would make local stops in Queens to fill in for R service. Brooklyn-bound F trains would
