The reason these trains are a design failure is the services they are to be used on. For a short 20 minute hop when crammed as full as a tube train their design may have a point. However for a long distance hour long journey specifying rediculously squashed together seats so your customers suffer is preposterous. And yes train customers will have to suffer these failures for many years to come. That is not something to celebrate, but should provoke an investigation to prevent it ever happening again.
