But nothing will happen before the election.

A group of parents whose children travel from Helensburgh to Heathcote High School or St John Bosco College in Engadine have called on the government to put on school buses.

‘‘Our high school children are currently commuting to our local feeder high schools Heathcote and Bosco by bus, train and foot,’’ said spokeswoman Nicole Geldart, whose son attends Heathcote High School.

‘‘The commute takes one hour and 10 minutes each way. That’s 11 hours and 40 minutes per week. The schools are a 15 to 20-minute drive away, so this commute time is ridiculous.’’

She also said there were concerns about congestion on the platforms and the trains, adding that the provision of buses would alleviate that.

Mr Evans said the government had already been looking into this issue. 

‘‘We have made a representation to the minister about it,’’ Mr Evans said.

‘‘It was looked at previously and it’s going to be reviewed again.’’

He said the same question was raised ‘‘a couple of years ago’’ and Transport for NSW investigated.

No buses were put on because it was decided the train service, which stops less than a kilometre from each school, was suitable.

‘‘We can’t just willy nilly put buses on without going through the process,’’ Mr Evans said.

‘‘It’s a fairly expensive exercise. There is transport there already in the trains but they don’t want them catching trains.

‘‘But Transport for NSW needs to prove that the assets they would be putting in would be utilised.’’

While Mr Evans said the issue was being looked at, no decision could be made before the March 28 election as the government would be entering caretaker mode from Monday.

‘‘It always comes down to whether the buses are well used,’’ he said.

‘‘The problem might be that, if we put two or three buses on, they won’t be full because the kids will choose to go on the train.

‘‘If you’ve got a bus available or you can go on the train with your mates, then you’ll go on the train with your mates.’’
