New South Wales has four public transport
light rail tram lines.
Sydney's L1 line has been suspended for up to 18 months because of defective trams.
Newcastle's (upon Hunter) single tram line has been closed indefinitely 'for operational issues'.
Sydney's L2 and L3 lines within the city between the busiest train station Central and the busy ferry terminal Circular Quay right through the heart of the city will be closed for maintenance from Friday night until Monday morning.
Two of the lines are suspended and the other two partly suspended.
Nice work, Transport for New South Wales.
