A woman is expected to be charged with drink-driving after allegedly driving her car on to the pedestrian overpass at a Melbourne train station.

Police say the 21-year-old woman used a ramp at Kananook railway station in Melbourne’s south-east to reach its overpass about 2am on Sunday morning and was stationary there for a short time.

The Malvern East woman then drove down three flights of stairs to return to the ground level, where her Mitsubishi ASX station wagon became stuck between steel handrails and needed to be cut out by State Emergency Service workers.

Police breath-tested the woman who returned a reading of 0.158, more than three times the legal limit of 0.05.

She is expected to be charged with drink-driving and careless driving.
