Dunheved is a major industrial, and commercial centre to the north. Between March 1942 and March 1986 Dunheved was served by a branch rail line that left the main western line approximately 200 metres west of St Marys station as part of the Ropes Creek branch line that was constructed to serve the munitions works formerly operated by Australian Defence Industries. While the rail infrastructure was left in place for many years after the closure, other than Dunheved Station platform and Ropes Creek Station (within the Ropes Crossing estate), nothing remains of this branch line beyond Christie Street.
