Images of the future £5.3 million Energlyn and Churchill Park station have gone on display to the public.
The new station will provide the area with direct access to and from Cardiff for the first time.
The Welsh European Funding Office has helped to fund the scheme, which has been developed jointly by the Welsh Government, Network Rail, Caerphilly County Borough Council, South East Wales Transport Authority (SEWTA) and Arriva Trains Wales (ATW).
The new station will be located between Aber and Llanbradach in Caerphilly county borough.
Mark Langman, route director for Network Rail Wales, said: “This proposal is driven by our plans to transform the railway in Wales and, when delivered, will mark a huge improvement for Energlyn and Churchill Park.
“Support from the people of the area is vital to make this possible and we welcome the public in having their say today.
“Caerphilly county borough has seen a steady increase in passenger demand in recent years and the new station will cater for this growth and encourage sustainable travel, whilst also helping to improve the local economy.”
