CR 6812 at Chester, MA in 6/1979. (2)

U28C 6823 adds tractive effort at the rear of the extra 6812 west going by Bay State Dr. in Chester, MA. in June, 1979. This was one of those rare times, in my experience, when the helper was added to the train at Huntington, rather than at Chester station, which is about 3/4 mile ahead.
