The new operator of trains between Portsmouth and London today revealed the staggering variety of items left behind by passengers
In its first six weeks of operations, South Western Railway says it has already accumulated more than 10,000 pieces of lost property.
The most common include umbrellas, coats and mobile phones - but the company's storehouse also includes some more bizarre finds.

Michael Pugh, Customer Experience Manager at Waterloo station (including Lost Property), said: 'Our staff from across the network work hard to ensure passengers are reunited with their belongings.
'However, we would encourage everyone to check they have their belongings before they leave our trains. Keys, phones and wallets are always such a pain to lose but it’s the sentimental items that really cause problems for passengers.'
Anything lost and found on South Western Railway stations (including items left on other train companies’ services) is sent to an office in London Waterloo and kept for three months.
Most of the items remaining unclaimed after three months are donated to charity or recycled.
SWR urges customers to use its online enquiry form to register a lost item or call the Lost Property Office on 020 7401 7861 (open Monday to Friday 07:30-19:00).
