As part of the changes, on January 30, all 242nd Street trains started running to New Lots Avenue. This change eliminated the splitting of trains at Brooklyn Museum, with the first half going to New Lots Avenue and the second half to Flatbush Avenue. In addition, the span of rush hour service on both Broadway–Seventh Avenue locals and expresses was increased. As of 1934, all express 1 trains were running from 242nd Street to New Lots Avenue weekdays and Saturdays during the day, alternating between New Lots and Flatbush Avenues evenings and Sunday afternoons, and were split at Brooklyn Museum on Sunday morning with the first half going to New Lots Avenue and the second half to Flatbush Avenue. All local 1 trains ran from 137th Street (extended to Dyckman Street during rush hours) to South Ferry days and evenings, and 242nd Street to either New Lots or Flatbush Avenues during late nights (from 12 am to 5:30 am). On September 5, 1937, the practice of splitting Sunday morning trains at Brooklyn Museum was discontinued, with the alternate trains going to New Lots Avenue or Flatbush Avenue. Trains were cut from being 10-car trains to 7-car trains. On July 1, 1938, all evening and Sunday trains were rerouted to New Lots Avenue. By 1945, all local 1 trains were cut back from Dyckman Street to 137th Street during peak periods. Beginning on May 10, 1946, all 1 trains in Brooklyn ran express during late nights, with service running every twelve minutes. Previously all 1 trains ran local from 12:30 to 5:30 am and they alternated between Flatbush and New Lots Avenues. On December 20, 1946, all late night trains were routed to Flatbush Avenue, while Sunday service still alternated between Flatbush and New Lots Avenues. On June 12, 1949, 137th Street to South Ferry Sunday local trains were discontinued, but were resumed on March 5, 1950, at which time Sunday service was also rerouted to New Lots Avenue. On March 15, 1954, weekend 137th Street to South Ferry local trains were once again discontinued, and simultaneously weekend Brooklyn trains were rerouted to Flatbush Avenue. An attempt was made to extend express service further north on January 14, 1955, when alternate rush hour trains ran express between 137th and 96th Streets in the peak direction. This proved unsuccessful, and ended on June 28, 1956. Meanwhile, in Brooklyn, weekday trains were rerouted to Flatbush Avenue and evening 137th Street to South Ferry local trains were discontinued.
