Cattle cars have been used to deport people before, but only from Arizona to New Mexico, that I know of.

The Bisbee Deportation was the illegal kidnapping and deportation of about 1,300 striking mine workers, their supporters, and citizen bystanders by 2,000 members of a deputized posse on July 12, 1917. The action was orchestrated by Phelps Dodge, the major mining company in the area, which provided lists of workers and others who were to be arrested in Bisbee, Arizona. The arrested were first held at a local baseball park before being loaded onto cattle cars and deported 200 miles (320 km) to Tres Hermanas in New Mexico. The 16-hour journey was through desert without food or water. Once unloaded, the deportees, most without money or transportation, were warned against returning to Bisbee.

At 11:00 a.m., the El Paso and Southwestern Railroad brought 23 cattle cars to Bisbee. The posse deputies forced the remaining 1,286 arrestees at gunpoint to board the cars, many of which had over three inches (76 mm) of manure on the floor. Although temperatures were in the mid-90s Fahrenheit,[12] (mid-30s Celsius), no water had been provided to the men since the arrests began at dawn.[3][4][5][6]

The train stopped 10 miles (16 km) east of Douglas to take on water, some of which was provided to the deportees on the packed cars. Deputies manned two machine guns from nearby hilltops to guard the train, while another 200 armed men patrolled the tracks. The train continued to Columbus, New Mexico (about 175 miles (282 km) away), arriving at about 9:30 p.m. Initially prevented from unloading at Columbus, the train slowly traveled back west another 20 miles (32 km) to Hermanas, not stopping until 3:00 a.m.[3][4][5][6][13]

During the Bisbee Deportation, Phelps Dodge executives seized control of the telegraph and telephones to prevent news of the arrests and expulsion from being reported. Company executives refused to let Western Union send wires out of town, and stopped Associated Press reporters from filing stories.[14] News of the Bisbee Deportation was made known only after an IWW attorney, who met the train in Hermanas, issued a press release

Worth reading the whole thing, because you know Trump is reading it.
