The final plans to build a £5.2m new station to serve Energlyn and Churchill Park in Caerphilly County Borough will be unveiled today at a public exhibition.
The new station will be located between Aber and Llanbradach.
Network rail says the new station aims to serve a growing community.
When it's finished it will be operated by Arriva Trains Wales.
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).
