The Cambrian Line connects Shrewsbury (where it connects to the Shrewsbury—Chester, Welsh Marches, and Wolverhampton—Shrewsbury lines), westwards with Mid Wales and towns along Cardigan Bay. The line is commonly split into two sections, the section from Shrewsbury to Aberystwyth is sometimes referred to as the Cambrian Main Line, with the Cambrian Coast Line, splitting off from this line at Dovey Junction, heading northwest to Pwllheli. The busiest station in 2017-18 on the main line was Aberystwyth, least being Dovey Junction, and on the coast line the busiest station was Barmouth, with the least being Tygwyn.
