It'll be a few days more before we hear the 'clang, clang, clang, of the trolley'.  Heavy snow has delayed of the Old Town trolley operated by the Fort Collins Municipal Railway Society. It was supposed to open on Saturday. Tree limbs brought down by snow took out electrical lines that power the streetcar near the Trolley Barn in City Park. Volunteers will repair the lines as soon as possible but not in time for the scheduled opening this weekend. The trolley operates May through September between Old Town and City Park along Mountain Avenue. Once operating again, fares are $2 for adults and $1 for kids and seniors
