‘‘I don’t care what the weather is,’’ said Lou Grimaldi, president of the Connecticut Trolley Museum. ‘‘They come year after year after year.’’ What they come for is Winterfest, a holiday tradition since 1970 — railroad fans riding six restored, century-old trolleys along 1.5-mile stretch of the old Hartford and Springfield line, through a tunnel of some 6,000 colored lights. The ‘‘Sleigh’’ trolley is the most popular, Grimaldi said. It’s one of only four built, with canted seating for alpine ascents. After the ride, visitors can check out the museum’s model train and trolley displays, live music, refreshments, and gifts from Santa for the children.
