Transport for London is making it a Christmas to remember with what Londoners forget.
Who hasn't accidentally left something behind when they've got off the Tube or a bus?
Well, among those hundreds of thousands of lost items are brand new toys.
And now some of them will become Christmas treats for lucky children.
Piers Hopkirk explains. He spoke to Paul Cowan, TfL Lost Property Office Manager and Captain Kevin Stanbury from the Salvation Army.
Transport for London has a vast selection of unclaimed toys, which they are giving away to charity.
Hundreds of brand new toys lost on London's transport network are being wrapped up to bring some seasonal cheer to needy families in the capital this Christmas.
Transport for London's lost property office is donating the mountain of toys that have been left on tubes, trains and taxis to the Salvation Army.
It will then distribute the gifts to disadvantaged families across the capital over the festive period. TFL's lost property office recieves around 50,000 items of lost property every three months.
Just some of the 50,000 items of lost property held by Transport for London at their lost property office in Baker Street. These items have been collected only in the last three months.
The lost property office at Transport for London has donated hundreds of unclaimed toys to charity.
The brand new toys and games found on its buses and trains have been handed to the Salvation Army.
They will work with councils to identify families in need of an extra gift this Christmas.
