I'm trying to understand what your suggestion is in the first recommendation. Are engineers not currently involved in the process of rail? Your suggestion is that the law needs to be changed to say that professional engineers, rather than engineering principles, have to be used. Are you suggesting that engineers are not currently used in the maintenance of railways?
