It was while George Mawbey I and his family were living at Dural that the Sydney to Parramatta railway line was opened.
This was the first government-owned, public railway line to be opened in Australia.
It must have been a momentous occasion, making it much easier for them to visit their relatives in Newtown.
The opening took place in 1854, prior to the last three Mawbey children being born, Elizabeth (b.1855), George (b.1860) and Mary (b.1862).
Steam trains plied the track between Parramatta Junction (Granville) and Sydney (the station then being located near Devonshire Street, between the present Central and Redfern stations).
There were six stations along the line, one of them being Newtown where the Mawbey relatives lived.
