Pennsylvania Railroad, Hunter Interlocking Tower, East end of Bigelow Street at Amtrak milepost 10.55, Newark, Essex County, NJ

Significance: Hunter Interlocking Tower is a classic example of the architecturally unadorned and utilitarian twentieth century interlocking tower, significant as an increasingly endangered historic property type. Interlocking towers have played an important role in safe railroad operations. Once a vital part of railroad operations and a common sight along railroad rights-of-way, these small unobtrusive buildings are rapidly being replaced by remote control interlockings.
