TFL are the integrated transport authority responsible for delivering Mayor of London Sadiq Khan's strategy and commitments on transport. TFL run the day-to-day operation of the Capital's public transport network and manage London's main roads.
The Tube handles up to 4.8 million passenger journeys per day. At peak times, there are more than 543 trains whizzing around the Capital.
Investing in the future
More people than ever are using the Tube, with more trains running than at any time in its history.
However, some of the equipment being relied on is decades old - including a signal box from 1926 still in use at Edgware Road.
For the Tube to continue working smoothly, continued improvements are essential.
TFL are carrying out a multi-billion pound programme to increase capacity and accessibility and to run services more reliably and more frequently.
This programme includes introducing new trains, signalling and track, and rebuilding some of the busiest and most complex stations.
TFL has partnered with Prospects College of Advanced Technology to train the next generation of skilled rail engineers.
The Skills Funding Agency fund skills training for further education (FE) in England. They support over 1,000 colleges, private training organisations, and employers with more than £4 billion of funding each year.
SFA is an executive agency, sponsored by the Department for Education.
