USB chargers, increased luggage spaces, updated buffet area and more comfortable seats are included in the final designs for the VLocity trains which will run on the North-East railway line post the $235 million track upgrade completion.
Six wheelchair spaces with companion seats located closeby, share tables for families or groups travelling together and cycle racks have also been included in the designs released by the Andrews Labor Government.
The design features were guided by discussions between the Transport Department, V/Line and North-East stakeholders including Border Rail Action Group, councils, accessibility advocates and tourism bodies.
They will be the first VLocity trains to run on standard gauge tracks on Victoria's regional network with a "rigorous" testing program also to be carried out before they commence.
"These new trains will provide North-East line passengers with a more comfortable and reliable train journey," Public Transport Minister Melissa Horne said.
"We'll be making these new trains in Dandenong, boosting the economy and supporting hundreds of local jobs in the process."
Train building company Bombardier will begin manufacturing the trains later this year at its facility in Dandenong and guaranteeing 500 local jobs.
Member for Northern Victoria Jaclyn Symes said the release of the final designs was an important milestone.
"We're working hard to deliver this important investment that will improve journeys for everyone travelling on our regional trains to the North East of our state," she said.
"The feedback from local passenger groups, accessibility advocates, local government and tourism representatives has been fantastic, and central to the design process.
"I thank everyone who contributed."
The North-East line VLocity trains are expected to have a top speed of 130km/h when they begin running in the second half of next year.
Three-carriage VLocity trains presently run on other lines in Victoria, but two trains are expected to be coupled together for a total of six carriages on the North-East line to provide around 296 seats.
"This is more than the four carriage Classic Fleet trains which currently service the North-East line," a government spokesperson said.
The North-East line works are being carried out by contractors John Holland Group on behalf of the Australian Rail Track Corporation.
There is presently an 80km/h speed restriction on the line between Albury and Melbourne due to the XPT train derailment at Wallan earlier this year in which a driver and pilot were killed.
