There is no railway station in Baulkham Hills. In the past, there was the Rogans Hill line, connecting the suburb to Parramatta. Railway Street near Baulkham Hills Junction is a reminder of this. It was closed down in 1930 due to traffic problems on Windsor Road and large financial losses. Land owned by the rail authority was sold to the Hills Bowling Club in the mid-1970s to build their two front bowling greens. The closest Sydney Metro Northwest stations are Castle Hill, Hills Showground and Norwest.
