Meet the lost property detectives
Roy Worboyes and Annie John work at a rail lost property office in the City of London.
Their job is to reunite passengers with their misplaced belongings and, if that's not possible, find a new home for these items.
Nearly 3,500 objects were left behind by Govia Thameslink passengers in 2021 - that figure was three times higher in 2019, the year before the pandemic changed travel habits.
