Amanda Hull has been missing since January 7 and her family and friends are becoming increasingly worried.
The 42-year-old was last seen wearing a grey/white hoodie black coat, black trousers and black knee-high boots, carrying a black Adidas backpack.
West Mercia Police have confirmed that Amanda boarded a train from Worcester Foregate Street to London Paddington at around 5.30pm on January 7.
Her sister, Kate Nicol, says she is increasingly worried, and that Amanda doesn’t know anyone in London.
In a Facebook post, Kate Nicol said: “We have had it confirmed by police that she boarded the train to London Paddington at 17.26pm on Tuesday January 7.
“She bought a ticket which they’ve seen from Foregate Street and are chasing footage from Great Western to see where she leaves the train.
“We believe that she will have stayed until the end of the journey at Paddington.
“Please share this with anyone in the London area as we are now increasingly worried about the time that has gone by, how far she is from home, and the lack of money.
“She doesn’t know people in London, we’ve linked to people we know and possible places she may go.”
West Mercia Police describe Amanda as white, around 5ft 1in tall, with brown hair and blonde highlights.
A spokesperson for West Mercia Police said: “Officers are concerned for Amanda’s welfare and ask if anyone has seen her, or knows of her whereabouts, to call 01905 331030 quoting 387_i of 7 January.”
