Is the Minister aware of the sardine express? It is the Arriva Trains Wales service that goes from Wales to Shropshire, then on to other parts of the United Kingdom. My concern is that people are being crushed into its carriages, because there are often only two carriages when four are required to meet the demand on the line. If there were a sudden halt or accident, far more people would be injured or, possibly, killed as a result of that congestion in the carriages. Will the Minister undertake to meet representatives of Arriva Trains Wales and get an undertaking from them that they will take action to deal with this, as it has been going on for far too long?
