This junction was the eastern apex of a triangular junction. Also known as Silvermuir East Junction or Silvermuir Junction East. The other junctions were Cleghorn Junction, to the west, and Silvermuir South Junction, to the south.
The curve opened for the opening of the Douglas Branch (Caledonian Railway) in 1864, an extension of the Lanark branch.
The original signal box was on the north side of the junction.
The box was replaced in 1934, as were all three junction boxes, with a single single box called Lanark Junction. This was set back but within the ^V^ of the junction.
The Silvermuir South Junction to Silvermuir Junction curve closed in 1968.
The Lanark Junction box closed in 1973, replaced by the Motherwell Signalling Centre.
