Thats not over engineering just crap design and using the latest toys for the sake of it. Overengineering is the Victorian egineers way of desiging as they did not have the indepth knowledge we have and so have massive margins of safety. Of course that means that some of the pre WW2 London Underground tains lasted longer than the ones bought in the 70's.
