We have steps under way now to strongly recommend the wearing of masks because we understand that, as capacity comes back, having a full two metres isn't something that's going to be practical to maintain service levels.
We are involved with enhanced cleaning. We've issued more PPE. Many systems are looking at engineering how people board so that there's more contactless payment and so that we keep the operator inside a barrier. We're taking a number of initiatives that we think will help to welcome the public back and rebuild some of the confidence about being in close quarters.
