R10 cars were placed into service for the extension. The cost of the extension was about $46.5 million. It included the construction of the new Pitkin Avenue Storage Yard, which could accommodate 585 subway cars on 40 storage tracks. Because these stations were completed later than the rest of the line, they received different design features than other IND stations, including different wall tiles and fluorescent lighting. The Fulton Street express tracks were not used in regular service until October 24, 1949. A trains began running express during rush hours to Broadway–East New York, with trains extended to provide local service. The express reduced travel time by five minutes. In 1953, the platforms were lengthened at Ralph Avenue and Broadway–East New York to to allow E trains to run eleven car trains. The began running eleven car trains during rush hours on September 8, 1953. The extra train car increased the total carrying capacity by 4,000 passengers. The lengthening project cost $400,000. In late 1952, the Board of Transportation began construction on a connection between the IND and both the Fulton El and the Rockaway Beach Branch of the Long Island Rail Road, which included a new underground station at Grant Avenue. The connection from the 80th Street elevated station to the rest of the BMT Fulton Elevated was severed on April 26, 1956, and the IND was extended east (track direction south) from Euclid Avenue via the intermediate station at Grant Avenue, and a connecting ramp (known as the Grant Avenue ramp). The new service to Lefferts Boulevard began three days later. On June 28, 1956, the connection to the IND Rockaway Line east of Rockaway Boulevard was opened. The 2015–2019 MTA Capital Plan called for the Fulton Street Line's Clinton–Washington Avenues, Kingston–Throop Avenues, and Van Siclen Avenue stations, along with 30 others, to undergo a complete overhaul as part of the Enhanced Station Initiative. Updates would include cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps, improved signage, and improved station lighting. However, in April 2018, it was announced that cost overruns had forced the MTA to reduce the number of subway stations included in the program from 33 stations to 20. The stations to be renovated along the IND Fulton Street Line were among the 13 stations without funding, which will be pushed back to the 2020–2024 Capital Plan. Second System planned route Early in
