I came across this the other day. I can tell you that the Railway line never eventuated, but it would have been interesting if it had. Cora Lynn never got a railway station - the closest stations were Tynong and Garfield on the Gippsland line and the Bayles and Catani Railway Stations on the Koo-Wee-Rup to Strezelecki line. This line opened on June 29, 1922 and closed in stages with the Catani station closing in April 1950 and Bayles in February 1959.
Here's what it says:
The Committee also took evidence at Nar Nar Goon and Messrs Reid and Latta were examined in regard to the proposed route. The latter gentleman said that he had been 29 (?) years on 700 acres of land and after that time his land was only now in a fit state to produce crops which would be valuable to him.
