Newport A box during construction of the Melbourne road overpass 1960. Interestingly all 4 arms applied from the down track only. Of particular interest is the short arm under the right hand home signal the The 1949 Book of Signals described it thus: "Arm, under the Bridge, Set-back signal from Up"
Line to Road required.
