Train passengers have been warned to expect delays on Sydney's T8 Airport and South Line until Thursday after a car crashed into signalling equipment and caused extensive damage, reports The Sydney Morning Herald.
The driver hit a location cabinet containing hundreds of wires for the signalling system on the T8 Line.
The incident has forced Sydney Trains to switch from automated to manual signalling along a stretch of the T8 Line, which in turn means trains have to travel slowly on tracks.
It has resulted in delays of up to 15 minutes on the T8 Line and has also caused minor disruptions on the T2 Inner West and T3 Bankstown lines.
Replacement buses have been put on to ferry passengers to intermediate stations on the T8 Line to Campbelltown.
Travellers are advised to allow 10 to 15 minutes extra to ensure minimal delays.
