The viability of a rail line from Canberra to Eden via Cooma was investigated after the NSW Government funded a $1 million study in 2018. The proposed route would include reinstating the majority of the disused Bombala Line, extending 100km to the coast at the southern end of the line and north 3.5km from Harmen to Canberra Airport. In October 2020, the viability study found the proposal would not be economically viable, given the costs associated with extending the line through challenging terrain to the coast.
