The Cambrian Coast Line, incorporating the former Aberystwyth and Welsh Coast Railway, runs between Pwllheli and Aberystwyth, via Dovey Junction and Machynlleth.
On the seal of the 'Aberystwith [sic] & Welsh Coast Railway Company' of 1861, is depicted a representation of a train crossing what is thought to be the proposed but not built viaduct across the Dovey/Dyfi estuary, between a point on the railway by Ynyslas Farm (now Ynys Tachwedd) (nprn 417597) on the south side and Penhelyg/Penhelig on the northern side. An alternative route was constructed, crossing the River Dyfi by the viaduct (nprn 96104) at Dovey Junction.
