I came across this report in the South Bourke and Mornington Journal (SBMJ) of November 20, 1919 about Railway returns in the SBMJ circuation district.
South Bourke and Mornington Journal November 20, 1919
As you might expect, Dandenong had the largest passenger traffic volume- £9,739, followed by Warragul, Springvale, Drouin, Pakenham, Clayton and then Koo Wee Rup, with £1,598. Dandenong also had the most parcel traffic, followed by Cranbourne and then Caldermeade, which I find extraordinary, as it is a very small town. Koo Wee Rup had, by far the most goods traffic £4,932 worth, with Tynong coming in second with £2,936 worth of goods traffic. Dandenong also led in livestock traffic, again not a surprise, as the Dandenong market was a major outlet for livestock in the region.
