What I can say is that we're considering a number of options at the moment. If the trains don't have—[Interruption.] Well, if the trains don't have toilets on board, then we would expect the operator to provide very much enhanced services at stations in order to ensure that people feel comfortable when they are travelling. There are, of course, examples of metro services elsewhere, such as in Greater Manchester, where there are no toilets on board, and quite often there are no facilities for passengers who wish to use a toilet. That is not what we want; we want to make sure that people are able to access toilet facilities as easily as possible.
