This junction was directly east of Duddingston station. It was formed in 1884 between the 1831 Edinburgh and Dalkeith Railway and the Edinburgh, Suburban and Southside Junction Railway.
Duddingston signal box (opened with the newer line) was located at the east end of Duddingston station in the 'V' of the junction. This was a double track junction.
The station's goods yard was built on the older line, approached from the east.
Craigmillar Brewery was on the south side of the newer line, served via a headshunt.
Further breweries were to open. North British Brewery (served by reversal from the westbound main line west of the station), Castle Brewery to the south (served from Duddingston Junction) and Craigmillar New Brewery to the south (served from the same junction).
The line east to Niddrie West Junction was quadrupled in 1900. Storage sidings were added on the north side of the junction, approached from the east.
A 'Hitler Siding' opened here in the Second World War.
Duddingston station closed in 1962. The St Leonards route closed in 1968 and the box was dispensed with in 1969.
