Very much so. This is one of the biggest public transport projects outside of London. It will utilise, of course, some of the existing lines that are already there. They're all heavy rail at the moment, and we'll need to see which will remain as heavy rail, which will be converted to light rail, which new routes would then be rolled out using light rail, alongside some of the existing routes that have rail tracks on them but haven't been used for many, many years. These are all matters that are being considered as part of the franchise tendering process.
