Congress/Douglas ran two car trains during middays, evenings, and weekends; this lasted well into the 70's after the Kennedy extension came online. Rush hour trains were six cars, and 6000s still made up the majority of the equipment, until the 2400s were delivered circa 1978; amd even then, it still took about 5 years for the 6000s to be completely phased out. Sometimes you'd see 4-car trains on this route on weekends during the holiday season, a practice that lasted into the early 80's; these were presumably "shopper's specials", and there would usually be a few 6000s in that mix.
Also, back then, you could always tell the end of rush hour when, on the Douglas branch, the last six-car train that ran past my house was almost always a 6000 series, and it was followed less than five minutes later by a two car 2200 or 2400; then it would just be two cars, usually of the newer equipment for the rest of the evening. Once in a great while I'd see a two-car 6000 series train in revenue service late in the evening, but that was pretty rare, and wouldn't happen again after 1980 or so. Ah, those were the days...
