I'm grateful to the Minister for his answer, particularly with regard to capacity. The issue of overcrowding on the railways was raised with the First Minister in this place yesterday. Unfortunately, that's not an isolated concern. Constituents from across the mid and west region have been contacting me citing real concerns about the line that runs across mid Wales to Shrewsbury in particular. Examples included delays ranging from 30 minutes to an hour being just routine and an increasing lack of carriages and seats on those trains—one constituent counting 26 people standing up in one carriage—and, obviously, I'm sure the Minister would agree with me that this isn't acceptable and it is regrettable that these were the same sorts of complaints that we heard under the previous franchise. Last July, the Minister provided us with details of the new franchise agreement that stipulates that Transport for Wales will be penalised if passengers are forced to stand for longer than 20 minutes. Could the Minister reassure my constituents that that commitment to reduce standing on trains will be honoured and could he give us some sort of idea of the timescale for the additional capacity that he mentioned to me in his original answer?
