Show FullscreenUSA: The opening of a 14·7 km extension from APU/Citrus College to Pomona has taken the Los Angeles Metro’s A Line to 93 km with 48 stops, which the operator said makes it the longest light rail line in the world; the tramway running the length of the Belgian coast covers 67 km. A Line services run every 8 min in the peaks, every 10 min off peak and every 20 min at night. $1·5bn construction projectShow FullscreenThe Foothill Gold Line Construction Authority was formed to manage development of the light rail line from Los Angeles Union station to Pomona in three stages, originally as the standalone Gold Line before the route was incorporated into the A Line (previously known as the Blue Line). Between Glendora and Pomona the extension parallels a BNSF freight corridor also used by Metrolink commuter rail services. The project required relocation of the freight tracks, installing a pair of electrified light rail tracks, rebuilding 21 level crossings and building or renovating 19 bridges.
