Umbrellas? We've had a few! Inside Transport for London's lost property office containing thousands of items from capital's tubes, trains and buses These are the incredible sights inside the Transport for London Lost Property Office. Made up entirely of items left behind on buses, trains and in taxis across the capital they have been handed over by members of the public and carefully categorised and stored in the offices in Baker Street awaiting the return of their owners. But for many belongings sadly that never happens and the storage rooms are now home to hundreds of thousands of items - 246,241 were handed in last year alone. Neatly packed: The TFL storeroom on Baker Street has become home to hundreds of thousands of lost items Forgotten army: Dozens of shopping trollies are lined up waiting to be collected Enough to keep you dry: 12,000 umbrellas have been collected and organised by staff after being found on buses, trains and in taxis Good humour: Staff at the storeroom arrange everything carfeully in the hopes that the items can be re-united with their owners The items left behind are themselves not surprising but the quantities they are collected in are vast - in total there are now more than 51,000 books, 12,000 umbrellas and 35,000 articles of clothing. There is also 29,000 valuables such as purses, wallets and cameras and cash, 27,000 phones and an astonishing 11,000 sets of keys. The staff then take their utmost care to find every item's owner by contacting people if they can or trying to match up enquiries with the belongings handed in. A lot to lose: You would think people would notice then they got home without their backpacks or cameras but 35,000 bags end up in the store each year Thanks to their efforts 52,000 people were happily reunited with their property last year, but so many items remain that they have to be carefully categorized to keep the vast quantities in order. They say they are continually impressed at the honesty with which the British public hand in missing items, even if they are valuable pieces of equipment or jewelerry. Time out magazine reported that the staff had even told them that the day after the iPhone 5 was released, someone handed one that they had found in instead of pocketing it. The key to the unknown: Thousands of house and car keys are left on public every year Lost: Sadly the ashes of one Thomas Frederick Johnston are amongst some of the more unusual items handed in Personal affair: Everything from creams to tablets and prescription medicine are found discarded or lost on public transport Miscellaneous: Some of the more obscure items found in the store are a puppet and a dead man's ashes. But despite all this there are still so many things left behind that after three months, everything is unpacked, sold at auction, used again or disposed of. Amongst the more unusual items found are 5,000 pieces of jewelerry, computers, and even the ashes of a dead man named Thomas Frederick Johnston preserved in a wooden box. The new edition or Time Out London is available this week. Collection in the making: One Arsenal supporting member of staff has even taken it upon themselves to start a grouping specifically for memorabilia connected to the club
