A significant number of commuters continue to fall through gaps between platforms and trains at Sydney's stations and get stuck in lifts each year, internal government figures show.

About 290 passengers fell through gaps between platforms and trains in the 12 months to last June, compared with about 340 in the 2016-17 financial year and about 305 in 2015-16.

Central Station, the city's busiest, topped the list last year with about 54 people falling through gaps, followed by Circular Quay (about 34) and Redfern (about 18), according to a Sydney Trains report obtained by the Herald under freedom of information laws.

About 120 people were trapped in lifts at stations across the rail network last year, down on the 140 a year earlier, but slightly higher than in 2015-16.
