Tornados that barreled through the Dallas-Ft. Worth area yesterday caused severe damage to equipment at Schneider National's Dallas operating center at 34511 Lyndon B. Johnson Freeway.

Video of Schneider's trailers being thrown in the air by winds went viral.

Reuters reported that truck driver Michael Glennon saw one tornado tear through the Flying J Truck Plaza in Dallas, grabbing two trailer trucks and tossing them.

Late yesterday afternoon, the company released a statement, saying: "This afternoon, a tornado struck the Dallas area, impacting our Dallas Operating Center. Based on our initial check, all driver, office, maintenance and offsite associates in the area are safe and accounted for. At this time, Haslet and the other locations appear to be unaffected. We continue to maintain our watch, since the weather continues to be threatening in and around Dallas/Fort Worth, including tornado warnings, hail and heavy rain. "

The company said the Dallas OC was not damaged, but equipment in the yard suffered "massive" damage.

"Operations will be restricted until we are fully assessed," Schneider said.

Schneider has about 65 maintenance and office workers at the site, and 200 to 300 drivers move through the facility daily. The company has 254 tractor-trailers and 204 trailers at that location.
