USA: A ceremony in Salt Lake City on October 22 marked the start of construction on the $300m Airport TRAX light rail line. The 9·7 km five-stop branch will diverge from the main north-south line at Arena, heading west to Terminal One. It is expected to carry 14 000 daily riders by 2030.

The project is part of Utah Transit Authority’s $2·8bn FrontLines 2015 programme, which includes the West Valley and Draper TRAX lines plus the FrontRunner commuter rail extension from Salt Lake City to Provo. The airport line is scheduled to be completed by early 2013, but UTA says problems with the economy, fuel costs and other factors could delay the work.
