The 746 mirrors both 747 and 46A routes. And the 746 could have great potential if the frequency of this service is increaced and publicised more.
I agree that the 746 would be excellent with a greater frequency. However, its misleading to say that the 746 mirrors the 747, the latter operates via the Port Tunnel most of the time while the 746 operates Via Swords Road, Santry, Whitehall, Drumcondra to the city.
