Honolulu's multi-billion-dollar rail system is taking shape. The first stretch of guideway for the island's elevated rail system is now up between columns in the farmlands of West Oahu. Rail officials, state and local elected leaders, and construction managers gathered Thursday at the site of the proposed controversial Ho'opili community development in Ewa to praise the new guideway work. Twelve individual segments form the first span, which was completed last week. Several hundred more spans will create the 20-mile guideway, which extens from East Kapolei to Ala Moana Center.
