The Harrington and Lowca Light Railway (commonly known as the Lowca Light Railway or LLR) was a short railway on the coast of Cumberland, which is now part of Cumbria, England. The line was originally an industrial railway, but by the early twentieth century it was carrying passengers in association with the Cleator and Workington Junction Railway (CWJR). This joint venture ended in 1929, and from that year onwards, the line reverted to industrial use. It closed in 1973, having outlived almost all its larger neighbours.
