Thank you very much, Deputy Presiding Officer. Minister, we know that delays on trains and overcrowding on trains can have a direct impact on the economy and productivity in Wales. A number of workers in Wales have to decide to leave home earlier in order to get on a train or to get to work on time; others arrive at their workplace late. Has the Government made an assessment of how much delay and overcrowding of trains cost the economy, including hours lost in the workplace?
