TRINIDAD, Colo. (AP) — A railroad crossing in southern Colorado where five family members, including three young girls, were killed when an Amtrak train slammed into their minivan had been targeted for safety improvements for years. The rural crossing near Trinidad, about 15 miles from the New Mexico border, was identified for improvements as part of ongoing work with counties and railroads to fix problem areas, said Amy Ford, a spokeswoman for the Colorado Department of Transportation. Las Animas County commissioners approved a joint application for the work with the state just two weeks ago.
