Expanding on what DRN said, during the week 1186/1188 originate in Stamford and deadhead to Waterbury. 1188 is the second deadhead, and that turns for the first southbound train as 1923 in the morning, with 1935 following. 1935 sits between BL-WATER and Division Post while 1923 sits in the station. 1935's equipment does the first three round trips on the branch, and 1923's crew and equipment does a round trip on the Danbury as 1806/1849.
