I would encourage anyone who loses an item of property on our services to get in touch with us
More than 110,000 items have found their way to the TfL Lost Property Office in the last seven months and thousands more are expected to be handed in over the holiday season.
December is traditionally a busy time for the Lost Property Office and last year more than 12,000 items were handed in - some of them Christmas presents in festive gift wrapping.
Julie Haley, Manager of TfL's Lost Property Office, said: 'We would like to remind people to keep hold of their belongings - it's all too easy to leave a bag or two behind when you're out shopping for presents or taking advantage of the January sales.
'We always do our best to reunite people with their property, and it's such a shame when we see so many presents going unclaimed.
I would encourage anyone who loses an item of property on our services to get in touch with us to claim it back in time for Christmas Day.'
Leaving items behind can also lead to unnecessary security alerts and delays to services across the transport network.
TfL is now reminding passengers to keep their belongings with them through a series of new security posters, designed both to reassure passengers and minimise unnecessary delays on public transport.
Steve Burton, Director of Community Safety Enforcement and Policing for TfL, said: 'Whilst it is the season to be jolly, leaving bags behind on the transport network can spoil the festive feeling.
'Unattended items can cause unecessary security alerts which are an additional burden to the emergency services and to passengers who get caught in the disruption that follows.
'The safety of our passengers and staff is our top priority and the new poster campaign has been designed to remind people to look after their belongings and be extra vigilant.'
Between 600 and 1,000 items are handed in each day to TfL's Lost Property Office.
The most commonly forgotten objects from 1 May to 1 December this year were books (21,844), bags (16,778) and items of clothing (16,614).
This is followed by a large volume of mobile phones, value items (wallets, purses, laptops etc.), umbrellas, keys and gloves.
A satellite dish, crocodile skin handbag, four foot gorilla soft toy, jar of bull's sperm and human skulls are just some of the unusual items handed in to the Lost Property Office over the years.
