The Story
On March 14, 1940, a train struck a truck carrying more than 40 farmworkers at this crossing near Alamo, killing 34 people ranging in age from ten to forty-eight—the deadliest highway accident in Texas history. A neighboring citrus packing plant became the base for frantic rescue efforts. The disaster shook the Rio Grande Valley and spurred new attention to railroad-crossing safety and the treatment of agricultural laborers.
Why it matters
The tragedy exposed the dangers faced by farm laborers and helped drive reforms in transportation safety.
The story behind this marker
AI contextThe era
In 1940 the Lower Rio Grande Valley was one of the most productive farming regions in the country. Irrigation from the Rio Grande had turned brush country into citrus groves and vegetable fields, and packing plants rose along the rail lines to ship grapefruit, oranges, and produce north. The railroad was the Valley's lifeline to distant markets.
Those fields ran on hand labor. Thousands of agricultural workers picked, cut, and packed the crops, many of them from Mexican American and Mexican families, as was typical of the region's farm workforce at the time. The country was only just coming out of the Great Depression, and work was precious even when it was hard, poorly paid, and dangerous.
Getting to work was one of the dangers. Workers were commonly carried to the fields packed into the open beds of trucks, with little regulation of how many rode or how. Rural railroad crossings, many without gates or signals, were a hazard everywhere in the country, and in a farm region full of trucks and trains the two kept meeting.
People & events
On March 14, 1940, a truck carrying more than 40 agricultural workers reached the crossing of Tower Road and the Missouri Pacific line, right here. An oncoming train hit it. Thirty-four of the workers were killed. The youngest was ten years old and the oldest 48, which tells you whole families worked the fields together, children included.
The neighboring citrus packing plant, a building made for sorting fruit, became the headquarters for the rescue. Neighbors, coworkers, and local responders worked to help the injured and recover the dead. In a community the size of Alamo, almost no one would have been untouched by the loss.
The grief spread well beyond Alamo, across the Rio Grande Valley. According to the marker, it was the deadliest automobile accident on a Texas highway in the 20th century. The disaster turned new attention to two problems: the safety of railroad crossings, and the way agricultural workers were transported to and from their jobs.
Its place in the American story
The Alamo collision is part of a larger and often overlooked American story: the people who grew and harvested the nation's food frequently did so at great personal risk, with few protections. Crowded, unregulated transport of farmworkers was common across the country for decades, and tragedies like this one became arguments for changing it.
It also belongs to the long history of grade-crossing safety. As cars and trucks multiplied in the early 20th century, the places where roads crossed railroad tracks became some of the deadliest spots in American transportation. The gates, flashing lights, and warning signs most travelers take for granted today came about partly because of disasters like this one.
Most of all, the marker is a reminder that history isn't only about founders and battles. Thirty-four working people, some of them children, died on their way to do the labor that fed the country. Marking this spot gives them a place in the public memory they earned.
If you visit
This is a place for quiet reflection. The marker stands at an ordinary crossroads, the meeting of a farm road and a rail line, and that ordinariness is what makes it powerful. Take a moment to imagine an early spring morning in 1940, a truck full of workers headed for the fields, and the moment everything changed.
If you're traveling with children, it's a meaningful place to talk about the workers who harvest our food, and why safety rules exist. The ages on the marker, from ten to 48, can open a real conversation.
Be careful here: this is still a working road and rail corridor, so park safely and watch for traffic and trains. Alamo sits in the heart of the Rio Grande Valley, with citrus country, wildlife refuges famous for birding, and the region's distinct border culture all nearby. This stop adds a sobering, human chapter to a Valley road trip.

Camp Ebenezer
Alamo, TX
In the early 1900s, ranchers Peter Ebenezer Blalock and George L. Hawkins amassed 32,000 acres in the lower Rio Grande Valley and built shipping pens beside a railroad depot they named Ebenezer. When their ranch was sold in 1909, the Alamo Land and Sugar Company transformed the tract into farmland, luring prospective buyers south on excursion trains and lodging them at "Camp Ebenezer." The depot's 1919 move a mile east seeded the town of Alamo.
San Juan Townsite
San Juan, TX
The town of San Juan sprang up in 1910 when Rio Grande Valley entrepreneur John Closner sold 406 acres to a townsite company that named the new community for him. Sitting on the rail line, San Juan quickly grew a business district along Fifth Street, and in 1911 raised its first two-story building—home to the San Juan State Bank and, over the decades, an irrigation office and other ventures. Today the surviving fragment of that pioneer building houses the city library.
San Antonio and Rio Grande Railway; "Old Flossie"
San Juan, TX
Beginning operations in 1909 and becoming a branch of the St. Louis, Brownsville and Mexico Railway in 1912, the line nicknamed "Old Flossie" carried freight and passengers to the young towns of Chapin (Edinburg) and San Juan during a pivotal era of Rio Grande Valley growth. Passenger service dwindled after World War II, and the Missouri Pacific system absorbed the line in 1956. By the late 1960s all service ended, the rails were pulled up, and the depots were razed.
Donna
Donna, TX
In the late 1890s, East Texans T. J. Hooks and A. F. Hester set out to develop this stretch of the Rio Grande Valley, forming the La Blanca Agricultural Company to lay out farms and irrigation and to advertise the region's climate. When a rail line reached the site in 1904 they founded the town, naming it Donna for Hooks's daughter. It incorporated in 1908 and grew into one of the Valley's leading cities.
