Mark Hardisty (NCE 2 September) may well, in principle, be justified in his criticism of the overuse of the title 'engineer'. However, the examples he uses are poor and even insulting.
Within firms working in the rail sector, the term 'permanent way engineer', albeit arguably archaic, is nevertheless a recognised title for professional engineers specialising in the engineering of railway track. It is objectionable for Hardisty, even if in jest, to link this respectable, established and recognised engineering sub discipline directly with such as window cleaners.
We engineers should not try and limit the disciplines' many diverse specialisations, but instead widely proclaim the high standards of the education and skills which we must attain to be permitted to use the title engineer.
