Curiously, and counter-intuitively, its no worse than if the Rhymney services were running to the Bay, as they all pass over the two track section over Queen St bridge.And the change in flows, with the Rhymney-Vale trains having to cross the Cathays-Bay ones around Queen Street.
What does introduce a conflict though is northbound trains from the Bay as they cross over southbound traffic departing Queen St.
I would imagine the rapid acceleration of the trams is expected to reduce occupation times throughout the Queen St area to minimise any congestion.
