Passengers are advised to use the relatively nearby D, N, or Q trains to reach their destination south of Church Avenue. Due to the proximity of other metro lines and buses, there will be no free bus service during the work.
The long break in service is that the MTA is installing a state-of-the-art alarm system. It will replace the existing analog signal system dating back to the Great Depression era. CBTC allows MTA operators to know the location of trains in tunnels much more accurately. This will allow trains to move faster.
MTA statistics show that the F train has a below system average on-time performance.
CBTC significantly improves the timely operation of the lines on which it is installed. The MTA notes that 7 trains improved their performance from 55,5% to 91% between March 2018 and March 2019. They installed CBTC in the winter of 2019.
The L train has been equipped with CBTC since 2012. And proudly claims the best time performance of any subway line in the system. The only exceptions are shuttles.
An MTA spokesman did not say why authorities briefed voters on the extent of the outage before informing the general public. Signage at Brooklyn F stations only indicates service consultation until October 7th.
