I understand capacity is an issue but companies and the DfT (in other cases) need to comprehend the fact that people are getting bigger, broader and taller. 3+2 is no longer welcomed by most and seats so close to each other aren't an improvement. Seats on some of Londons buses look more spacious. that's not even mentioning the actual comfort of the seats in terms of cushioning and padding which is another issue within itself. We basically sabotaged ourselves from the beginning with our narrower guage and although I understand there's not really any other affordable options, high capacity trains won't last us forever. By the next couple of generations of trains across our whole rail network, high capacity trains will no longer be the answer. Big money should be spent and big changes need to be made but there's unfortunately no money there, I do wonder how we will tackle overcrowding in future, we've already done all the 'quick fix' options.
The trains do look good though, I actually don't mind their front although I think all the different coloured lights inside feels a bit too colourful.
