At this junction trains from Glasgow to Edinburgh divide from those from Glasgow to Stirling and Perth. It is the junction between the former Edinburgh and Glasgow Railway of 1842 and the Scottish Central Railway of 1848. Both lines are double track.
There was an interchange station here, Upper Greenhill, between 1848 and 1865. A small goods yard was at the very western extremity of the Scottish Central Railway, just west of the station.
This was also the junction for a goods line which ran east on the south side of the Edinburgh and Glasgow Railway. The signal box was located between this line and the main line. The western end of this line and a few sidings remain today, now permanent way sidings.
The goods line ran on south side as far as the east end of Bonnybridge High station serving several brick. From west to east these were: Glenyard Brick Works, Dykehead Firebrick Works, Milnquarter Brick Works, Bonnyside Foundry (Stirlingshire Iron and Stove), Bonnyside Brick Works and Lochview Foundry Siding.
Greenhill Upper box took over several other boxes. Roughcastle Junction, Gartshore Siding, Lenzie Junction in 1971. The box was renamed Greenhill Junction in 1975 when it also took over Greenhill Lower Junction and Greenhill South Signal Box.
The box was relocated into a switchroom to the south of the lines in 1999. It box closed in 2017. It was retained as an emergency panel. Now Edinburgh Signalling Centre controlled.
