The TA decided to implement skip-stop service with two services labeled "J" and "Z", with lightly-used stops designated as "J" or "Z" stops, and those with higher ridership being all-stop stations. In addition, J and Z trains skipped Bowery in Manhattan at all times except evenings, nights and weekends. To further speed up service, J and Z trains would run express between Myrtle and Marcy. Trains on the J/Z ran every five minutes, an improvement over their previous headway of eight minutes. Skip-stop service ran to Manhattan in the morning between 7:15 and 8:15 a.m. and to Jamaica between 4:45 and 5:45 p.m.
