Unions are preparing to rally once again at a local MP's office this week, demanding the state government commit to building new trains in Ballarat.
Alstom workers will protest outside upper house MP Jaala Pulford's office, on Dana Street, on Wednesday at noon.
Ballarat Regional Trades and Labour Council's Brett Edgington said unions vowed to rally every two weeks until there's a resolution - a fortnight ago, they were outside Wendouree MP Juliana Addison's office on Lydiard Street, and there's been positive signs since.
"After the last rally, local members did make contact with union representatives," Mr Edgington said.
"We want to send a strong message - get on with the talks and get us an announcement."
The state government has consistently said it will make a decision when a thorough assessment for Alstom's next generation metropolitan train designs is completed.
Unions say more than 70 jobs at the 102-year-old factory are at risk if a new contract isn't signed before current works conclude.
