From My local newspaper, the Caerphilly Campaign:-
A Proposal to build a new station at Energlyn will be on show this evening at an exhibition, where the public is encouraged to give feedback. The new station, which will be located between Aber and Llanbradach, aims to serve the growing community at Energlyn. Once completed, the scheme will benefit passengers at Energlyn with direct rail services to and from Cardiff for the first time, potentially within two years.
Developed jointly by the Welsh Government, Network Rail, Caerphilly County Borough Council, SEWTA and Arriva Trains Wales, the plan will significantly help ease road congestion and cater for rising rail usage in the area.
The plan proposes that the new station consists of two platforms with step-free access.
