Disabled commuters have been left disadvantaged because the Queensland government has continued to run of a fleet of trains that don't meet national standards, an advocacy group believes.
The $4.4 billion fleet of next-generation trains were denied an exemption by the Australian Human Rights Commission after it was discovered the trains have no disabled toilets and limited access for wheelchairs.
Despite that ruling the state Labor government has continued to operate the trains, a decision criticised by advocacy group People with Disability Australia.
"Access to public transport is vital so that people with disability can get to work, study and recreation," spokeswoman Frances Farrant said on Tuesday.
"The decision to use inaccessible trains has been outrageous and ignores the rights of people with disability to use public transport, just like everyone else."
Premier Annastacia Palaszczuk announced on Monday former judge Michael Forde would lead an independent inquiry into the procurement of the flawed trains.
Acquisition of the trains began under Anna Bligh's Labor government when Ms Palaszczuk was transport minister.
A contract was later signed off by Campbell Newman's LNP government, with the first of the Indian-made trains arriving after Labor returned to power in 2015.
Delays and ongoing problems with the rollout of the 75 trains has drawn criticism from both sides of politics.
Almost 60 passengers were trapped underground last month when a fault caused by one of trains damaged power lines, leading to widespread delays.
The incident resulted in another train on the Brisbane airport line breaking down in a tunnel for over an hour, with passengers evacuated via an emergency exit and one needing medical treatment for anxiety.
Canadian company Bombardier is undertaking work to fix the trains at the railyards in Maryborough, northwest of Brisbane.
