Changing operational procedures and traffic patterns have seen a lot of changes occur to the largest facilities built in the 1960s as part of the standard gauge project.
LEIGHTON / NORTH FREMANTLE. No standard gauge track in Leighton Yard. Changed access to North Fremantle and North Quay terminal remodelled.
ROBB JETTY Eliminated.
KWINANA One facility which has expanded since construction with new sidings and extension to grain terminal.
KEWDALE Most private sidings now gone, parcels shed demolished.
FORRESTFIELD Rationalised, notably with removal of narrow gauge hump yard and storage sidings.
AVON YARD As noted, though much infrastructure still remains.
WEST MERREDIN Track rationalisation, removal of gantry crane and private sidings (except CBH), closure of signal cabin.
WEST KALGOORLIE Intact, though signal cabin closed.
For the record, the Aurizon locos still stored at Avon Yard are AB1502, 1503: DAZ1902; AD1520, 1521.
