One of the goals of the project was to make Jamaica Avenue service as attractive as possible, and as a result, the NYCTA planned to provide a form of express service. The two options considered to speed up Jamaica Line service were skip-stop service, which would have split Jamaica services into two patterns that served alternate stops, and a zone-express service, which would have split Jamaica services into a short-turn local service and a full-length express services. The zone-express option was dismissed in favor of the skip-stop option because its operation has to be very precisely timed so as to not hinder reliability, because service in the outer zone past the boundary of zone express service at Crescent Street or 111th Street would be too infrequent, and because many stations would lose half their service. Outer-zone expresses after Crescent Street would skip stops on the local track until Eastern Parkway, from where it would run on the express track, stopping at Myrtle Avenue before going straight to Essex Street in Manhattan, skipping Marcy Avenue. Outer-zone expresses and inner-zone locals would have each been limited to frequencies of 10 minutes.
