SO02150624

Part of the plateway system connecting various ironstone and coal levels on the NE slope of Mynydd Aberd're with Cyfarthfa Ironworks.
(SO02150624-SO01810638).

1884 (OS 6-inch 1st Edn.): A line running from a reversing junction from the branch from Winch Mawr, to an ironstone level west of Ochr-y-mynydd.

1905 (OS 6-inch 2nd Edn.): From the reversing junction the line was cut back to a coal level a short distance to the S. The reversing junction had been eliminated by an extension of the line westwards. This and an deviation at the western end rendered the sections between SO02140617 and SO01950631, and SO01870636 and SO01810638 obsolete.
