Cwmystwyth is to be built in 2021.
Planning showed Cwmystwyth needed to be able to pass passenger trains so given the board
size the only practical option is an island platform as used by Chelwood and Criel-sur-Mer.
The prototype for this is Haven Street station on the Isle of White
I've mocked up the station board using Criel-sur-Mer.
Access to the platform would be direct from the road with the station building on the platform.
The shop might be Rivington Camping and Outdoor Equipment or if an oil depot is preferred Emo Oil.
Alternately Emo Oil might be the 'possible industry'.
