MTA New York City Transit today announced plans to develop and purchase up to 949 new subway cars with an open-gangway configuration, designed for the numbered lines, that would increase passenger flow to allow customers to move freely between cars, and have the potential to improve dwell times at stations and increase capacity. The move comes as the MTA prepares for a major resignaling project on the Lexington Avenue 456 lines and the planned retirement of its R62 and R62A fleets that have been in service for more than 30 years.
