Nine cars of a Union Pacific freight train derailed this afternoon as it passed through San Marcos, shutting down West McCarty Lane for about three hours.
Six cars full of new automobiles fell over alongside the track at about 3:15 p.m. today as the train traveled from Laredo en route to St. Louis, said Raquel Espinoza, a Union Pacific spokesperson. Three other cars came off the rails but did not overturn.
The stretch of McCarty Lane between Interstate 35 and Hunter Road was reopened shortly after 6 p.m. The cause of the accident is being investigated and crews will work through the night to clear the scene, Espinoza said.
