Assistant Commissioner David Driver from the Traffic and Highway Patrol Command said the woman was walking with her family, including her husband and three-year-old son, when she was struck by a Kia Carnival.
He said that the Kia, being driven by a 48-year-old man, was attempting to enter the railway station car park, but slowed down to give way to pedestrians.
The Kia was then hit from behind by a white BMW being driven by a 19-year-old man.
Neither of the male drivers was injured, but both were taken to Hornsby Hospital for mandatory testing.
'This is a terrible, terrible story'
"Any serious crash is very confronting for first responders and particularly tragic when people pass away and indeed when there are children involved," Assistant Commissioner Driver said on Saturday.
"This is a terrible, terrible story."
The 19-year-old man was arrested at a home in Millewa Avenue, Wahroonga, at 12:45am on Saturday and was taken to Hornsby Police Station.
He was charged with dangerous driving occasioning death — drive manner dangerous, negligent driving (occasioning death) and cause loss of fetus — death of pregnant woman.
He was refused bail and will appear before Parramatta Local Court on Sunday.
Assistant Commissioner Driver said he believed the incident had been captured on CCTV footage.
"The exact nature of that I can't comment on yet," he said.
Officers from Ku-Ring-Gai Police Area Command established a crime scene that was examined by officers from the Crash Investigation Unit.
Anyone with information about the crash is urged to contact Hornsby Police Station or Crime Stoppers.
