Ms Martin has written to Michael Matheson the new Cabinet Secretary for Net Zero, Energy and Transport, to discuss extending the network in her constituency.
She wants the rail line from Dyce extended to Ellon.
In December last year, Mr Matheson confirmed to Ms Martin that a “number of interventions” had been identified in the North-east, including the possibility of a new rail line.
Ms Martin, who has campaigned on rail extention issues since she was first elected in 2016, said: “I would like to welcome Mr Matheson to his role as Cabinet Secretary for Net Zero, Energy and Transport.
“I’ve been campaigning for a rail link between Dyce and Ellon for five years, and I know many residents are keen to see it realised.
“As we look towards a green recovery from the impact of the coronavirus pandemic it is important we consider further rail options which would allow more people to commute and leave their cars at home.
“With our national ambition to reach net zero and connectivity being an important issue in the north-east I feel the time has come to ensure we can make the area more accessible with improved transport links.
“The Scottish Government has shown previous commitment to considering this issue and I look forward to meeting with the Cabinet Secretary to discuss future consideration of how we improve transport options here in the north-east.”
