Beige scarf lost on train near Clapham Junction

Lost a beige/cream scarf (a gift from my mom when I entered uni) on train when it stopped at Clapham Junction. The train was leaving from London Waterloo at 21:22 to Weybridge on 16th December. A lady seemed to have found it and folded it for me but when I tried to collect, the door was locked. Please reach out if you still have it. I truly appreciate it!
