The state government is yet to decide whether to continue funding the Overland train service between Adelaide and Melbourne beyond the end of 2019.
It comes as Member for Lowan Emma Kealy calls for upgrades to Horsham Station as part of the ongoing push to reinstate passenger train services to between the city and Melbourne.
The Overland runs twice weekly between the two capital cities, stopping in Nhill, Dimboola, Horsham, Stawell and Ararat.
In December, the state government committed to providing $3.78 million to help fund the route for 2019, after the South Australian government withdrew its funding for the service.
A Department of Transport spokesman said discussions into the long-term future of public transport services between Melbourne and Adelaide were ongoing.
"We're working to find the best way to provide regular, reliable public transport connections across western Victoria - including looking at the long-term future of the Overland," he said.
The spokesman also said the government was reviewing improving bus services in Stawell and Horsham, including extended operating hours, better coverage and Saturday services.
Emma Kealy said if passenger rail was to return to Horsham, the facilities needed to be brought up to scratch to be ready to receive commuters.
"At the moment there is not a lot of access for trainspotters or passengers," she said.
"I have received complaints from Overland passengers about the limited seating and lack of public toilets. If we let it get run down I don't think we'll get passenger rail back."
Horsham's University for the Third Age group leases the building from Horsham Rural City Council, which in turn leases it from VicTrack.
U3A President Bob McIlvena said he supported new station facilities being built next door, rather than the existing building being renovated.
"The first thing to keep in mind is the station is the same as it was in 1879. It's totally inadequate to act as a place for people to wait for trains or even assemble," he said.
"On occasion we have one of our groups interrupted by an Overland passenger wanting to use one of our private toilets.
"This is our base, and you have 300 people with nowhere to go, so if you're going to consider reopening it for train travel purposes, you've got to find somewhere for us to go.
"I think the cost of rehabilitating the station would far outweigh the cost of a new building. This station is probably best suited for a museum, but the platform is still in a reasonable condition. There is a tonne of vacant space around here."
Mr McIlvena said the organisation had 300 members, having started off with six 31 years ago.
He said it moved to the station 20 years ago, and now holds 32 courses for elderly Horsham residents including exercise, table tennis, language, board games and history.
