We are able to, on a periodic basis, calculate the amount of time lost and then, setting that against average earnings, we are able to assess the sort of loss to the economy as a whole. Clearly, we do not wish to see any time lost for passengers and we don't wish to see a penny lost for the economy, and that's why we're investing £5 billion in this franchise period in the new franchise agreement, including £800 million for new rolling stock and almost £200 million for improved stations.

We're also integrating public transport better through legislation, including the buses (Wales) Bill and further reforms on bus services; the introduction of better infrastructure for active travel and for bus rapid transport, so that people can choose to leave their car at home in full knowledge that they'll be able to get to work by public transport in just as little time as they would by their own car, if not in less time than that.
