Editing Corris Railway (section)

=== Quarries served ===
The principal reason for the existence of the Corris Railway was to serve the slate quarries of this district. Although usually referred to as quarries, those on the [[Narrow Vein]] were usually underground mine workings, following the course of the vein, while those on the [[Broad Vein]] were more usually opencast quarries. The outliers in the south of the valley were also opencast. This list shows the main quarries that the railway served:

* [[Morben quarry]] - an early quarry that was connected to the CM&RDT by an incline
* [[Ogo Fach Quarry]] - an early quarry connected to the CM&RDT by a short tramway through a tunnel.<ref>{{cite journal |first=Anthony |last=Coulls |author-link=Anthony Coulls |title=The Corris, Machyhlleth and River Dovey Tramroad |journal=Early Railways |volume=3 |year=2006}}</ref>
