The Grand Junction Railway (GJR) was an early railway company in the United Kingdom, which existed between 1833 and 1846 when it was amalgamated with other railways to form the London and North Western Railway. The line built by the company was the first trunk railway to be completed in England, and arguably the world's first long-distance railway with steam traction. Presently, the lines which comprised the GJR form the central section of the West Coast Main Line.
