The M4 east of Cardiff is affected by many factors. The metro will have some effect, but not as great an effect as for those communities that are to the west of Cardiff. Initially, of course, what the metro will do will be to upgrade and improve the existing railway lines, and then, of course, look to expand via light rail to new communities. But the next phases of the metro that include light rail are some years away, given the fact that we know that the initial work will focus on the heavy rail lines that already exist. But there are significant opportunities for modal shift via the metro in the years to come.
