Investment in new signalling, track and trains has cut delays by more than half since 2003. Train frequencies on the Victoria and Northern lines are now among the highest in Europe and new air-conditioned trains are being introduced to 40% of the network.
We have also partnered with Virgin Media to bring WiFi to a total of 250 London Underground stations and The Cloud to bring WiFi to more than 79 London Overground stations. We have launched all night services on two Tube lines, with more to follow this autumn. Read more about Tube improvements.
We've introduced new technology, like live bus arrivals, to help improve our customers' journeys, and are looking at innovative ways to reduce our environmental impact through projects like electric bus trials and our hybrid bus programme. Read more about bus investment.
On London Overground, we're adding an extra carriage to trains, so that we'll have increased the capacity of the network by 25%. We've also installed WiFi at 79 stations and made a range of other improvements, such as improving ticket halls and ticket gates, installing lifts, widening entrances, improving shelters and increasing cycle parking.

To make it easier for everyone to travel, around a quarter of Tube stations, half of all London Overground stations, most piers and all DLR stations now have step-free access from street to platform, and all our buses have low-floor access. We've also introduced tactile paving, audio-visual information, wider gates at stations and a range of accessible journey planning tools. Find out more about how we are making transport more accessible.
There are now many ways to pay for your travel. As well as Oyster, you can use contactless payment cards on the bus, Tube, DLR, London Overground, tram and most National Rail services in London. This now includes contactless payments using a mobile phone or device too. With an online account, you can see your journey history, top up your Oyster card with pay as you go credit or add a Travelcard and apply for refunds. Read more about ways to pay and ticketing.

The construction of Elizabeth line is continuing at pace - 26 miles of new tunnelling will be complete this year. When it launches in 2018, Elizabeth line will bring 10% more capacity to London's rail network and will have created thousands of new jobs.
Opened in June 2012, the Emirates Air Line was built to support regeneration in east London. The new cable car service runs between the Greenwich Peninsula and the Royal Docks. Over 3.5 million passenger journeys have been made since it opened.
Since taking over the line in 2015, we've invested in improving the service by ensuring there are staff on duty at every station from first to last train and providing cleaner trains and stations. We have made a commitment to improve reliability and frequency on the line and integrated customer information with the rest of our network. TfL Rail will form part of Elizabeth line in late 2018.
