Forrestfield, 30 June 1988: M1852 hauls 4 wheel superphosphate wagons over the hump. As the train passes into the yard, locos AB1533 and G50 head out together to pull QR silver coaches on peak hour commuter trains. In its turn M1851 also heads over the hump while in the background F40 can be heard being readied for its next roster.
