The last 19 Queensland-based employees of one of the world's largest train companies will finish work today, with its Maryborough manufacturing base closing down after nearly four decades.

Canadian company Bombardier Transport manufactures 33 per cent of the world's trains.

At its peak in the late 1970s and 1980s the company employed about 100 skilled workers at its Maryborough base.

In the past few decades the company has carried out contracts for Queensland Rail, Victorian Transport and West Rail.

Earlier in the year the company cited the increasing costs of manufacturing in Australia for its closure.

Redundancies were handed down in April and August this year, with the remaining workers to finish up today, along with its supply of trains for Western Australia Transport.

Lloyd Cosgrove, 59, has worked at the Maryborough facility for 25 years as a trades assistant, electrical apprentice and full-time train electrician.

"It's quite incredible that for such a long period of time, 38 years, we have built trains here," Mr Cosgrove said

"All Queensland passenger trains have either been built by us or EDI Downer in Maryborough."

He said it was disappointing manufacturing was going offshore and skilled workers from regional parts of the country were being lost.

"There is no local content in this latest huge contract for manufacturing of passenger trains in Queensland, so consequently it's cheaper for them to build them overseas and there is no requirement by the government for them to have any local content," he said.

"We are putting out perfect trains, but we are losing our jobs."

'The loss of skilled employment is a blow for our economy'

Fraser Coast Mayor Gerard O'Connell said it was a sad time for the region and the state.

"It's quite a set of tragic circumstances and it's symbolic and symptomatic of what is happening of manufacturing in Australia.

"The more we outsource ... our contracts, typically they go to cheaper options overseas," Cr O'Connell said.

He said the Wide Bay region was notorious for a lack of jobs and the latest closure has added more pressure to the local economy.

"The loss of skilled employment in an area like ours is a blow for our economy," he said.

"For generations in the city of Maryborough we have developed skilled workers and honed skilled tradespeople, grandfathers, fathers and sons have all worked here."

Three workers from the Maryborough facility have been offered contracts in India to teach workers how to manufacture parts for the trains.

The majority of Queensland trains will now be made in India and China.
