Residents of a Melbourne suburb that has been waiting 125 years for a rail line have just found out they'll have to wait at least another 30.

Doncaster has no rail or tram lines despite plans first being proposed in 1890 and construction actually starting in the 1970s.

Now Infrastructure Victoria has laid down a 30-year strategy for the state and "filtered out" plans for a Doncaster rail line.

"This option has a high cost, and feasibility studies indicate that few people will change to public transport if a heavy rail service were available compared to the existing bus service," Infrastructure Victoria's report says.
