i was a penrith student.
Well, i live in Cabramatta so i dont know what station you need to get to to use the trains. I think you need to catch a bus to get a train station but than it might be a waster of time.
go to
www.131500.info for ways to get to your destination.
For me, Cabra station is like 3 blocks from my house so its a 10 min walk than take the train. When you get there there is a special *free* service bus for students of UWS which comes every half hour and taeks you to werrington or kingswood campuses. Or if you miss the bus or need the excerecie, you can walk to campus from kingswood station, its like 10 mins if quick or 15 if slow walker. just walk in the direction of the 7-eleven and then you see this park and go to it and follow the concrete path.
But if youre going to UWS on a normal school day, you can always ask the students, theyll be wearing bags and look young.
