The 10-mile length of the Canarsie Line is also shorter than the majority of other subway lines. The relays controlled the train's starting, acceleration, braking, and stopping, as well as the opening and closing of the car doors. At these stops, gap fillers extend out from the platforms to bridge the space between the platform and the car body and door at the curved stations. The New York City Subway system differs from other railroad chaining systems in that it uses the engineer's chain of 100 feet (30.48 m) rather than the surveyor's chain of 66 feet (20.12 m). The lights on current signals, from top to bottom, are green, yellow, and red. :12 Originally slated to be completed by 2017,:20 ISIM-B was later delayed to 2020. :xv, "Gap filler signals" are used at the 14th Street–Union Square station on the IRT Lexington Avenue Line and at the Times Square–42nd Street station on the 42nd Street Shuttle station. However, installing CBTC in the New York City Subway is harder than in other systems due to the subway's complexity. :110–111:Chapter 2. As a result, the signaling requirements and complexity of implementing CBTC are easier to install and test than the more complicated subway lines that have junctions and share trackage with other lines. Because of the age of the subway system, many replacement parts are unavailable from signaling suppliers and must be custom built for the New York City Transit Authority, which operates the subway. :110–111:75–77, The old signals break down more easily, since some signals have outlasted their 50-year service life by up to 30 years, and signal problems accounted for 13% of all subway delays in 2016. The most used scheme is used on all B Division lines, originally built to the Brooklyn–Manhattan Transit Corporation (BMT) and Independent Subway System (IND)'s wider specifications, and on most of the A Division lines, built to the narrower specifications of the Interborough Rapid Transit Company (IRT). That system became the standard for all future CBTC installations on New York City Transit tracks as of 2015[update].  The wayside controllers themselves are located in enclosed boxes that can withstand floods and natural disasters. It was eventually found that the automated trip took 10 seconds longer than manual operation (about 95 seconds, compared to 85 seconds).  After the fire that destroyed the automated shuttle subway cars, ideas for New York City Subway automation lay dormant for years, until an intoxicated motorman caused a train crash at Union Square station that killed 5 people and injured 215. The most common new york subway sign material is polyester. , The first two lines, totaling 50 miles (80 km) of track miles, received CBTC from 2000 to 2018.  If the test succeeded, it was planned to automate the IRT Flushing Line, the BMT Canarsie Line, the BMT Myrtle Avenue Line, the Franklin Avenue Shuttle, and the Culver Shuttle. , These signals work by preventing trains from entering a "block" occupied by another train. The first type, "two-shot timers", are generally used on down grades where the train must be under a set speed for a longer length of track. With over 400 stations, please use the search field to search for the sign name or email us for personalized assistance. , Speed limits have remained relatively unchanged even as improvements in track geometry and car design allow trains to operate at higher speeds.  While in its experimental period, the automated train was only operating during rush hours. Should Culver Line express service be implemented, the express service would not use CBTC, and testing of CBTC on the express track would be limited to off-peak hours. The only place in the world specializing exclusively in vintage New York subway signs, and signs from all around the world, used as art and chiq office and home decor.  A home signal is defined as an interlocking signal at the entrance to a route or block to control trains entering that route or block.  Some of these time signals malfunctioned: they prevented trains from passing even if the operator had slowed down the train to the speed that was indicated, and so some operators slowed trains further in case a time signal forced trains to wait for longer than was indicated.  A third supplier, Mitsubishi Electric Power Products Inc., was given permission to demonstrate that its technology could be interoperable with the Siemens/Thales technology.

The BMT Canarsie Line was the first line to implement the automated technology, using Siemens's Trainguard MT CBTC system. The total cost was $99.6 million, with $15 million coming from the 2005–2009 capital budget and $84.6 million from the 2010–2014 capital budget. In addition, 68 locations had been approved for increases in speed limits. The remaining segment of the Flushing Line, between the Steinway Tunnel and 34th Street–Hudson Yards, began operating in CBTC service on November 26, 2018. New York Subway Signs Aluminum and vinyl signs are custom built and crafted to the exacting specifications of the MTA's graphic design specifications.  However, the CBTC retrofit date was later pushed back to 2017 and then to 2018 after a series of problems that workers encountered during installation, including problems with the R188s.  The R188 cars were ordered in 2010 to equip the line with compatible rolling stock.  The core of phase one was originally supposed to be completed by 2020 or 2021. When the signal is red, the gap fillers are extended, and when the red light is no longer lit up, the gap fillers have been retracted, and the train operator can increase the speed of the train and leave the station.
