1948 Twin Coach 44-S (Chicago Transit Authority 1700-1799 series).
In December 1947 Chicago Transit Authority ordered a group of 100 Twin Coach 44-S buses which were delivered started from January 1948. The dual-engine 44-D buses of 1800-1817 series were rebuilt by Twin Coach to single-engine version in 1949-1950 and they were thus indistinguishable from the 1700-series. The 1700-series buses were used almost exclusively on the North Side. This class was withdrawn from service in 1963-1964. [Photo: Jim Husing Collection].
