By 2018, CBTC was in the process of being installed on several other routes as well, particularly the IND Queens Boulevard Line () and IND Culver Line (). Eventually, the MTA has plans to automate a much larger portion, using One Person Train Operation (OPTO) in conjunction with CBTC. At the current pace of installation, it would take 175 years for CBTC to be installed at a cost of $20 billion. The Flushing line operated at almost 30 trains an hour using the signal system installed when the line was built, but after CBTC is installed it is possible that an additional two trains per hour could be operated. In March 2018, New York City Transit Authority president Andy Byford announced a new plan for resignaling the subway with CBTC, which would only take 10 to 15 years, compared to the previous estimate of 40 years. This would cost $8 to $15 billion.
