Thank you very much for the reply, Cabinet Secretary. Data provided by the Department for Transport show that rail passengers in South Wales East and south Wales are faced with some of the worst overcrowding in England and Wales. Nearly 40 per cent of train services arriving in Cardiff during the morning rush hour in 2015 had passengers who were forced to stand during the journey. What is the Welsh Government doing to address the issue of overcrowding on commuter train services, and will he comment on reports that spare rolling stock from the Gatwick express could be transferred to Arriva Trains Wales next year?
