Queensland’s newest fleet of trains, which have been plagued by disability access issues will be examined by a government inquiry.

Hundreds of problems need to be rectified across at least 35 trains, including braking, air-conditioning, ventilation and sightlines for train drivers.

The $4.4 billion trains also failed disability access tests, with the Human Rights Commission refusing the Government an exemption from disability compliance laws.

Premier Anastacia Palaszczuk announced on Monday evening retired District Court Judge Michael Forde would conduct an inquiry into the procurement of the trains, and their failure to comply with disability laws.
