These carriage sidings were developed on the west side of Aberdeen Joint, at its south end, access from Denburn South Junction. The sidings date from around the 1908 reconstruction of Aberdeen Joint and these sidings replaced earlier, much shorter, sidings on a similar site.
Entry was controlled by a short lived signal box 'Clayhills Sidings' (1908-1914) which was subsumed by Denburn South Junction box in 1914.
The sidings remain open today. In addition to the carriage sidings there is a train washer, shed and fueling road.
To the west was Clayhills, literally a clay hill with a brick works.
