Has your judge's wig gone missing? Misplaced your prosthetic leg? If so, you might do well to check Transport for London's lost property office, which counts these among the strange and wonderful items found on the capital's trains and buses.
More than 300,000 objects were handed into the office last year, a record amount that is likely to increase as the network continues to serve more and more customers.
