Aberdeen Railway Station could be expanded by reopening platforms which have lain disused for 40 years.
The proposals have been unveiled as a result of the proposed demolition of Atholl House.
Under the plans, a 463-bed student accommodation block, 192-room hotel and a public square would be built on the site.
Network Rail has outlined plans to bring platforms eight and nine back into use as well as a range of other improvements to the existing facility.
This would allow more trains to come to and from the Granite City and the north-east.
A spokesman for the operator: “We are looking into all the options available to improve the station and make it more passenger-friendly, but some of the options are quite challenging.”
The firm has already consulted with 28 organisations who are supportive of the proposals.
Among them, Transport Scotland, British Transport Police and Nestrans have all backed the scheme.
The city council’s administration has also supported the station revamp.
Finance convener Willie Young said: “The opening of the platforms will get more trains running, which is positive.
“We want more commuter trains similar to what Glasgow and Edinburgh have instead of people going on the road from Stonehaven, Inverurie and Kintore.
“This is why we are also keen to deliver links at Dyce.
“The more people we can get to travel by rail the better it is for our road infrastructure.”
