The Las Vegas Monorail reopened and began carrying passengers along the Las Vegas strip on Dec. 24, after being closed for three and half months due to technical glitches. Closure of the monorail cost more than $9 million in fare revenue, the Washington Post reported. Since its July 2004 debut, mechanical problems plagued the 4-mile system, which connects to major hotel-casinos and the Las Vegas Convention Center. Glitches have ranged from the doors opening doors on the wrong side of the cars, which exposed passengers to a 25-foot drop, to a 60-pound wheel assembly falling off during service. After receiving approval from Clark County officials, the system reopened for the Christmas weekend, just in time for Las Vegas' busiest tourist week of the year. Free rides were offered for five days following the monorail reopening, which drew a record 45,000 passengers on Christmas, according to the Post.
