Billups Neon Crossing Signal
A bold 1930s railroad grade-crossing installation in Grenada, Mississippi, featuring an overhead neon gantry, striking warnings and a loud siren; an early experiment in automobile–train safety.
The Billups Neon Crossing Signal was an experimental and highly visible railroad warning installation erected in the mid-1930s at a dangerous grade crossing on Mississippi State Route 7 in Grenada, Mississippi. The device was the creation of inventor Alonzo Billups and was intended to alert automobile drivers to approaching trains more forcefully than conventional signs and lights. The crossing's location is associated with Mississippi State Route 7 and the community of Grenada, Mississippi, where frequent collisions between road vehicles and trains prompted the unusual design.
Design and principal features
Rather than a simple roadside sign or pole-mounted light, the Billups installation used a large steel gantry that spanned the highway and stood above the travel lanes. On the gantry were oversized neon panels and a pair of flashing red lights, together forming an arresting visual display. The neon panels reportedly displayed the words "Stop-DEATH-Stop" and included a neon skull-and-crossbones motif; additional neon arrows flashed to indicate the direction from which a train was approaching. For auditory warning the installation used a powerful air-raid–type siren instead of the bells or electronic horns commonly used with later grade-crossing systems.
Origins and safety context
Alonzo Billups developed the system in response to repeated accidents at that particular crossing. During the 1930s motor vehicle traffic on public roads was growing rapidly and engineers, railroads and local inventors explored a variety of technological approaches to reduce collisions. The Billups structure exemplified a dramatic, attention-grabbing strategy intended to overcome driver inattention and poor visibility by combining very large visual elements with an unusually loud audible alarm.
Operation, problems and decline
Although striking in appearance, the Billups installation experienced practical difficulties in service. Electrical faults were reported, and the air-raid siren could activate erroneously and remain sounding until railroad personnel reached the site to reset it. During the years around and following World War II, neon tubing and related materials became scarcer, complicating maintenance. Because of these reliability and supply problems, no additional installations of the same design are known to have been built, and the single known gantry was removed after fewer than two decades in place.
Significance and legacy
The Billups Neon Crossing Signal is of interest to historians of transportation and traffic control as an early—and unusually conspicuous—attempt to integrate overhead visual signals with roadway design. While modern grade-crossing systems now use standardized flashing lights, gates, bells and electronic notification, the basic idea of using an overhead gantry to display warnings to motorists persists in highway and rail practice. The Billups device is often cited as a distinctive local experiment that prefigured later uses of gantries and overhead signals, even though it remained a one-off installation and was ultimately judged impractical for widespread adoption.
Notable distinctions
- Unique combination of neon signage, skull-and-crossbones imagery and an air-raid siren for a grade crossing.
- Installed in the mid-1930s by a private inventor in cooperation with the railroad to address a specific safety problem.
- Known as a single, short-lived installation removed after under twenty years and not replicated at other crossings.
Questions and answers
Q: What was the Billups Neon Crossing Signal?
A: The Billups Neon Crossing Signal was a special signal to warn car and truck drivers that a train was coming. It was placed at a dangerous Illinois Central railroad crossing on Mississippi State Route 7 in Grenada, Mississippi.
Q: Who invented the Billups Neon Crossing Signal?
A: The Billups Neon Crossing Signal was invented by Alonzo Billups in the mid-1930s.
Q: Why did Mr. Billups invent this signal?
A: Mr. Billups and the railroad were worried; the crossing had many accidents between trains and motor vehicles, so he wanted drivers who were going to cross the tracks to know that a train was coming and he wanted to do it in a very big way.
Q: What did the signal look like?
A: The signal was built like a giant steel gantry which went up and over the entire highway, with flashing red lights similar to those used today topping giant neon signs on either side of the big gantry. The signs lit up with words "Stop-DEATH-Stop" along with a neon skull and crossbones, as well as flashing neon arrows pointing toward the train to tell drivers which way it was coming.
Q: How did this signal warn drivers of an incoming train?
A: In addition to its visual warnings, this signal also used sound - instead of electric or electronic bells used now, it used a very loud air raid siren when warning drivers of an incoming train.
Q: Why wasn't this type of signal ever built again after WWII started?
A: After World War II started, neon became hard to get for these signals, as well as having electrical problems such as often having its air raid siren go off even if no train was coming and not shutting off until repair crews came from the railroad company itself. Therefore no more of these special signals were ever built after WWII began.
Q: How long did this particular crossing signal last before being taken down? A: This particular crossing signal lasted less than twenty years before being taken down after WWII began due to lack of materials needed for production and electrical issues with its air raid siren system
