This was a two road shed in the south east part of Troon Harbour at the south end of the eastern harbour wall. It probably dated from the 1840s and closed in 1935. Locomotives stabled here were used at Troon Harbour and in the area as far north as Irvine (including Irvine Harbour and the various works there), east to Kilmarnock, and Falkland Yard in the south.
The shipbreakers West of Scotland Shipbreaking Yard (owned by Arnott Young) was developed to the east on an expansion of the eastern harbour wall and locomotives as well as ships were to be scrapped here.
