Transport Scotland has reportedly confirmed that a Changing Places facility will be installed in Dundee train station by the end of the year.
Campaigners have been pushing for the specialist toilet facility at the refurbished station but were initially met with opposition when planners said there was not enough space.
But pressure from charity Pamis (Promoting A More Inclusive Society) persuaded ScotRail to make the investment in the facility.
Changing Places include specialist mobility equipment such as ceiling hoists, adjustable changing benches and adaptable WCs.
Transport Minister Humza Yousaf gave the green light for the facility in June. It is estimated that it could cost around £85,000 to contract a company in the industry to supply and install the facility.
Changing Places are currently recommended for train stations and other transport hubs but they are not compulsory.
MP Paula Sherriff recently delivered the first reading of a Bill in the House of Commons calling for Changing Places to be made compulsory in certain buildings.
The Ten Minute Rule Bill wants regulations that would place a mandatory duty on large new builds, public complexes and transport hubs to install specialist toilet facilities that include ceiling hoists, adjustable changing benches and adaptable WCs.
