In British India there was a Viceroy's Commissioned Officer, subordinate to all King's Commissioned Officers, but senior to all British Other Ranks (including Warrant Officers)
VCOs were treated and addressed with respect. Even a British officer would address a VCO as, for instance, "subedar sahib" or <name> "sahib". [Wiki]
He would be entitled to second-class travel on the railways (same as BORs)
