DESPITE a 46 per cent rise in trips on Melbourne's trains in the past four years, the State Government will deliver just one new train this year.

The contract for 18 new trains, signed last year with French train maker Alstom, has recently been posted on the Government's contracts website.

It shows that, despite Premier John Brumby's repeated assurances that new trains are on their way, relief for commuters from severe overcrowding on the city's trains won't occur this year.

"We have got a whole lot of new rolling stock coming online," Mr Brumby said last week when questioned about overcrowding.

But the new contracts with France's Alstom, worth 170 million euros ($A335 million), show the train manufacturer will deliver just one train by December 31.
