The S.S.44 / Berk Signal Tower was built in 1896 and remained in continuous service until 1984, a period of 88 years. Sixty-eight "Armstrong" levers, a busy four-track signaled and electrified mainline, a junction with a non-signaled branch line and a four-track swing bridge over the Norwalk River, all included in this one premier railroad interlocking, made S.S.44 / Berk "The Classic Railway Signal Tower." This book is about the New Haven, Penn Central and successor railroads, and the role that S.S.44 / Berk and the other signal towers played in their train operations, dispatching and control.
