Names and dates

Strawfrank Junction (1872-1972)
Carstairs South Junction (1972-)

Station code: CAJ National Rail ScotRail
Opened on the Caledonian Railway.


This junction is where the West Coast Main Line from the south divides, the western line running to Glasgow Central (and the north) and eastern to Edinburgh Waverley. Carstairs station is just to the north on the Glasgow fork.

This location was known as Strawfrank Junction. It is the southern end of the 1872 curve from [[Dolphinton Junction]. A signal box opened with the junction, a tall box on the west side of the line just north of a road bridge. The box was built 3 storeys high to see over the bridge. This was a double track junction.

The box lasted until preparations for electrification of the West coast Main Line. It was replaced by a temporary panel box at Carstairs station.

The junction name was changed to Carstairs South Junction. The Edinburgh line's connection was turned into a single lead junction, the line doubling to the immediate north of the junction.
