Gallagher claims World Cup win
Competing in the visually impaired Super Combined, Gallagher and Evans were fastest over both the downhill and slalom portions of the event to finish well ahead of Russian world champion Alexandra Frantseva.
Gallagher said: "Charlotte and I worked really well today. We had a lot of fun and it's just training for the big event."
Gallagher is Great Britain's biggest hope of claiming a medal at Winter Paralympics in Sochi in March.
Along with Evans, she became the first Briton to win a medal at the IPC World Championships when she took a silver and bronze in Sestriere in 2011. She followed it up with three more medals in the World Championships in La Molina, Spain, last year.
