A worldwide search to try to find the best companies to build Brisbane’s tunnels and metro vehicles is about to start.

Brisbane City Council is progressing with its $944 million Brisbane Metro, first announced in 2016, with plans to take the project to the market within weeks.

The council has said it wants a 25-metre-long metro vehicle that can carry 150 people, has Wi-Fi and can run through underground tunnels at the Cultural Centre and Adelaide Street.

Now the council are looking for a company who can build and supply the vehicles.
