I worked for the Boston & Maine 1968-86 and commuted into Boston until late 1983 when we moved out to Billerica. Up until the fleet showed signs of really aging by the mid-1970s, the longest morning consist came in from Lowell, 6 cars arriving North Station about 7:45 am and immediately made a turn to Woburn. During the spring-summer & fall months in that era, the RDCs were left overnight at outlying points shutdown. The cars at South Acton, Reading and Ipswich (and probably Rockport and Lowell) were brought in all coupled together on Saturday mornings, and not usually the first trip but mid-morning. They were run through the Budd House. The five South Acton cars usually were returned Saturday afternoon. The Reading and Ipswich consists, all coupled together, made the return move Sunday evenings, not too late. The large consists in both directions were on regularly scheduled trains. Usually one car open, the rest deadhead. After the big Chelsea fire in 1973 - on a Sunday night - the Monday services from Rockport and Ipswich were combined into a single train and ran via the Saugus Branch - reportedly 17 cars, probably the record.
