This morning, I visited Transport for London's tram depot at Therapia Lane to see how Tramlink is run, how the trams are maintained and what plans TfL have to improve the network.
Since Boris took responsibility for Tramlink in 2008, he has already increased the frequency of the service on parts of the network in the evenings and at weekends and invested substantial amounts in improving the basic infrastructure - replacing worn out track and refurbishing the trams. Now he wants to buy some additional trams so that he can increase the frequency on the central part of the network between Therapia Lane and Elmers End and in the long-term a number of extensions to the route are under consideration.
Then it was into the car to drive down to Gatwick to see the work the new owners are doing to improve passengers' experience of the airport.
They have already improved the shuttle between the two terminals and over the next year they are planning to spend something like £1 billion - great news both for passengers and for the many Croydon businesses that are dependent on the airport. I was particularly impressed with their plans to reduce queues through security (and provide assistance to people like me with young children, both to improve their experience and avoid them holding other passengers up) and in the Immigration Hall when you come back into the country.
