Trachsel won two medals at the FIBT World Championships with a silver in the two-man event (1977) and a bronze in the four-man event (1979).

A civil engineer by trade, he insured the required specifications, quality and schedule for sliding sport venues, including the Olympic tracks in Park City, Utah and Lake Placid, New York, and he provided early engineering guidance for the design of the Olympic track at Whistler Mountain for the 2010 Olympic Winter Games.
