Corporate History and Overview

Traffic Signals Inc. (TSI) was the short-lived successor of Southern Signals. TSI formed in 1960 when Southern Signals changed the name of Southern Signals to Traffic Signals Inc. They were bought by Singer in 1970.

Traffic Signals

TSI based their 4-ways off of Sargent Sowell's design. All of their signals used Dzus fasteners for latches and the visor collar was wider than most signals.

Four Ways

TSI only made one model of 4-way. They had the option of having an internal controller.
A TSI 4-way signal in use in Cullman, AL.


Adjustables

The back of a TSI 12-8-8 signal. Used with permission from Highway Divides user mnence1 (Drew).
TSI made 8 inch and 12 inch single-face signals. The main difference between the two is that the 12 inch ones have two latches instead of one.
An 8 inch TSI single-face signal in an antique store in Athens, AL.


Pedestrian Signals

TSI made some pedestrian signals. Not very many of them are known to still be in service. Here's a list of TSI pedestrian signals that are known to still be in use:

Location City, State # of Signals Lens Style Lens Size Status
Market Street and Marion Street Athens, AL 2 Walk/Don't Walk 9 inch Out of service as of January of 2019.
Kings Highway and Line Avenue Shreveport, LA 8 Walk/Don't Walk 9 inch Still in use as of May of 2019.
Kings Highway and Woodlawn Avenue Shreveport, LA 1 Walk/Don't Walk 9 inch Out of service as of March of 2019.
Dayton Street and Voge Street West Alexandria, OH 2 Walk/Don't Walk 12 inch Still in use as of June of 2019.

Vehicle Heads (Round)

TSI made an 8 inch Wait-walk signal that used the body of an 8 inch signal. None are known to still be in service.

Pedestrian/Sign Heads (Rectangular)

A TSI pedestrian signal displaying "Don't Walk".
A close-up of a TSI pedestrian signal.
A TSI pedestrian signal displaying "Walk".
The backs of a pair of TSI pedestrian signals.

TSI made a 9 inch pedestrian signal that used a 10x12 rectangular door that held the 9 inch lens. The backs of them looked like regular TSI heads except they were more elongated. TSI also made 12 inch pedestrian signals and they used standard TSI 12 inch sections.

Controllers

A TSI 4-way beacon with a compartment for an internal controller. The compartment is empty and is missing the cover.
A TSI mechanical controller case. It currently houses an electronic flasher.
A TSI mechanical flasher case. It currently houses an electronic flasher.

TSI made internal and external controllers. The internal controllers could only be used on the 4-ways.

Hardware

A TSI cluster with TSI cluster hardware.
TSI made hangers, cluster hardware, and blank doors for the signals. It is unknown what else they made.
A TSI blank door.
A TSI hanger.
