Production: 1961 - 1969

History
The 163 Single Block Signal is very similar to the 353 Block Signal of the same era. The 163 Signal has a red and green light in the signal and is used in conjunction with a 153C tract activator. It's a reliable accessory and realistic in its operation.

Construction of the signal remained virtually unchanged during the entire 1960's. The only minor change occurred in 1968 to the color of the base, going from beige to more of a tan color.

Features
The 163 Single Block Signal contains the following features: beige plastic base, white pole and a black signal head. There is a single lens allowing either the green or red light to show through the lens when activated by the track activator.
