All routes were double decker except 14. All served Patricks St except 10.
Routes 18 and 18a were on bus stops in the city, but did not run. I think there was also a 4a as a variant on the 4.
By 1975, the 1 and 2 had been merged; the 4 was southside to Friars Walk only; and route 12 had been introduced. Other changes to 5, 7, 7a, 9, 10, 11 and 14 came later. Also to come later was moving routes 2 and 6 off Patrick St.
