Tatiana Day will see less of her one-year-old daughter Evangelina if the NSW government goes ahead with proposed changes to the South Coast train timetable.
The Stanwell Park resident, who works in Sydney, said a leaked draft copy of the new timetable showed she would be forced to leave home earlier and arrive home later.
"I'm heading back to work after 12 months of maternity leave and the proposed changes by the O'Farrell government means we're going to have our daughter in childcare for an hour to an hour and a half longer each day," Ms Day said.
She said under the existing timetable, she could catch the 7.09am from Stanwell Park and walk in the door at work at 8.25am.
The proposed changes remove that stop, meaning Ms Day would have to catch the 6.31am train to get to work on time.
Coming home now, she could catch the 5.12pm train from Central and be at Stanwell Park at 6.16pm.
Under the draft timetable, that service no longer exists. So, Ms Day could get the 5.06pm from Central, get off at Otford at 6.08pm and then wait until 6.43pm for a train to stop and take her the one stop to Stanwell Park.
"I can't not go back to work," she said. "I'm hoping that my employer is going to be somewhat flexible in terms of me arriving later and leaving earlier because childcare in the area doesn't extend beyond the times that I would need to leave and get home."
Ms Day has started the Transport for All campaign and website to highlight the effect the timetable changes will have on residents in the northern suburbs.
"There have been a number of locals who have got on board who are affected by the changes," she said. "One of them, which is quite disturbing, is for kids who go to school in the Engadine or Heathcote area: there's one [direct] train around about the 3.30pm mark, and if they don't catch that train, they've got to wait until about 5.20pm for the next [direct] train coming home."
A Transport for NSW spokesman said extensive consultation over proposed changes was undertaken in 2012. He said the proposed timetable was still being confirmed and customers would be given plenty of warning ahead of its October introduction.
