'Commercial Road, Lowestoft in the days when it still had railway lines accessing it for goods from the North Quay and to Lowestoft Harbour Engineers Works which had a long history in the town including an ironworks and concrete depot plus a track across the Station Square/Commercial Road junction to the Harbour Goods Line.
