These lines received their Act in 1890. The Act was for several line portions to connect existing lines and produce new through routes. The principal route was a double track goods only line south from Jerviston Junction to Shields Colliery Junction serving the area east of Motherwell where the Dalzell Iron and Steel Works and Glasgow Rolling Stock and Plant Works were expanding and the Lanarkshire Steel Works was planned. This core line provided a goods only route connecting the main line to the south with the expanding marshalling yard at Mossend Yard.
A connection was made to the Wishaw Estate Railway which served various collieries near Wishaw and east of Motherwell.

This line is divided into a number of portions.
The first portion of this route used the northern part of the original alignment of the Wishaw and Coltness Railway to Motherwell Junction. From near the Jerviston Viaduct, which was not reused, it ran south east and then south to Coursington Road and the Lanarkshire Steel Works before continuing to Shields Colliery. The latter portion (Shields Colliery to Lanarkshire Steel Works) was the first part built.
This junction was south of Milnwood Junction. Most recently (1993) it provided access to the line to Ravenscraig No 3 Yard used for trips from Mossend Marshalling Yard to deliver limestone to the works and take strip coil away. It had also served the sizeable Clydesdale Steel Works yard, which closed slightly earlier.
This was a double track junction controlled by a signal box on the east side of the junction, just south of the Coursington Road over bridge. Trains approaching from the north could go south west to the Dalzell Steel Works or south east to Lanarkshire Steel Works and on to Shields Colliery Junction. Immediately to the north of the road bridge were sidings for a pumping station (west) ...More details
This signal box was built on the Motherwell New Lines (Caledonian Railway) on the first portion of this line, authorised in 1890 and running from Shields Colliery Junction to north of Lanarkshire Steel Works. This was originally a reversing spur for the works until the line was extended on to Cousington Road Junction Signal Box in 1900 and the Lanarkshire Steel Works box opened.
This was a large junction and west end of a yard which commenced at Shieldmuir Junction to the east.
