The line ran from the South Quay at Maryport, and the Maryport passenger station was in front of what is now Jubilee Terrace. The line was extended from Arkleby to Aspatria on 12 April 1841. Bridges on the line were built with little more than a foot (0.3m) lateral clearances between bridge and train; much less than came to be the norm in the UK, and as a consequence unwary passengers have in the past stuck their head out of a window and been killed.
