Paramedics assessed several light rail passengers at the scene near Central station, and a woman in her 70s who suffered chest injuries was taken to St Vincent’s Hospital in a stable condition.

A firefighter in his 40s suffered minor injuries and was taken to Royal Prince Alfred Hospital.

“This occurred in a really busy part of the CBD with a lot of pedestrians so we’re thankful that no one was seriously injured,” NSW Ambulance inspector Ben Saywell said.

The incident caused spin-off effects for traffic, with parts of Pitt Street closed to traffic and L2 and L3 light rail services also suspended between Central and Circular Quay.
