, the line was, from the start, used by trains of the Shrewsbury and Chester Railway, later to be incorporated into the Great Western Railway. So important was the line in the 19th and early 20th centuries to passenger, mail and freight traffic between Britain and Ireland that the world's first experimental and operational water troughs were installed at Mochdre, between Colwyn Bay and Llandudno Junction. Their purpose was to enable steam engines (especially on the Irish Mail) to collect water without stopping. Later, considerable stretches of line between Chester and Colwyn Bay were quadrupled to increase line capacity, but these sections have now been reduced to two tracks.

Modern day

In 2018, a £50 million signalling upgrade programme was completed between Shotton and Colwyn Bay. This upgrade saw modular colour lights supervised from the South Wales Rail Operating Centre in Cardiff replacing the manual signal boxes and mixture of semaphore and older colour lights.

The Welsh Government would like the line to be electrified, especially if Crewe becomes a rail hub due to HS2 in 2026. Chancellor George Osborne said in July 2015 that there was a "really strong case" for electrification of the line. The Electrification Task Force said that the Chester to Crewe line was a Tier 2 priority for being electrified in the CP6 period (2019-2024).
