Campaigners hope a changing places toilet at the revamped Dundee train station could be open by the end of the year.
The toilets are specially designed for people with disabilities, with more space than a traditional disabled toilet and a range of specialised equipment, including a hoist for helping people with severe mobility issues.
Disability charity Pamis (Promoting A More Inclusive Society) put pressure on ScotRail to include the changing places facilities after realising they were not in the original plans for the station.
The rail company initially said there was not enough space, but later relented and agreed to an evaluation.
Transport Minister Humza Yousaf agreed the toilets could go ahead last month.
Liberal Democrat councillor Fraser Macpherson said he had been informed by Transport Scotland that the toilets would be ready by the end of the year.
A spokesman for the company told him the works are likely to cost about £85,000 and bosses were confident the toilet would be installed before the end of the year.
Councillor Macpherson said: “It will enhance the improvements at the rail station.”
Pamis said the lack of a changing place toilet would damage Dundee’s reputation as an accessible destination if visitors were forced to cross to the V&A to use the nearest available facilities.
