What brought an end to the chisholm trail?

The Chisholm Trail came to an end primarily due to the expansion of railroads, which offered a more efficient means of transporting cattle to markets. Additionally, the overgrazing of pastures and the introduction of barbed wire in the late 19th century restricted cattle drives and access to open range. The combination of these factors, along with changing cattle ranching practices, led to the decline of the trail's prominence in the cattle industry.
