According to the Handbook of Texas, no distinct community formed until 1883, when the Gulf, Colorado and Santa Fe Railway built its tracks through the area. A post office followed in 1887, putting Haslet on the map.
“He has let us go through”
The City of Haslet’s history tells the story this way. When a Santa Fe representative came to the Maloney ranch asking for a right-of-way, Maloney first refused. Later Mrs. Maloney remarked that it would be nice to be able to ride the train into Fort Worth. Maloney changed his mind and told the railroad crew they could come through. When a workman asked what he had said, the answer was: “He has let us go through.”
The railroad contractor, from Haslett, Michigan, is said to have replied, “We’ll name this stop Has let.” The city’s account dates this to 1886.
