I’ve never really got why those three routes are grouped any more than with the 4 or others given how little crossover there really is.  South of the river the 3 shares virtually no common route with the 12, and only New Durham Road and Allendale Road with the 13. Even North of the river the only route they share that is ‘unique’ is North Hylton Road/Washington Road (from where they lose the 4 & 16 at Beaumont Street).  The 12 and 13 yes, but the 3 is pretty separate imo.
