Completion

The J Sutton Wall reference suggests that the tunnel was completed through Mt. Washinton as early as 1861, and used to transport coal before the Pittsburgh and Castle Shannon took over in 1871. Further documentation would be appreciated. Pustelnik (talk) 00:40, 2 May 2009 (UTC)[reply]

The coal incline connected to the north end of the mine had to be in operation sometime between 1825 and 1861, which would pre-date the Duquesne Incline, Pustelnik (talk) 13:56, 9 May 2009 (UTC)[reply]
